Betting Baseball Futures by the Numbers

The interpretation of how baseball was to be viewed differently came about with Bill James book “Baseball Abstract”. He and his fellow scribes developed an illuminating way to no longer take a batting and earned run averages at face value, rather look inside the numbers to understand what it really might mean. The term “sabermetric” became part of the language of baseball in the late 1980’s and still is widely renowned in today’s world.

This has lead to other methods of interpreting statistics, opening the door for Baseball Prospectus and Baseball-Reference.com to name a couple. This in-depth type of analysis of numbers has benefited fans and those who love to wager on baseball. For those seeking opportunity to place futures wagers on baseball, being able to see halfway thru the season eliminates some of the guess work that appeared cumbersome back in March.

Today you have a track record to follow and an inkling what might occur in the last 81 games of the baseball season. The oddsmakers do also, and a San Diego preseason wager of Over/Under 74 wins at Sportsbook.com looks safer today then it did before the season started. However, the corrective reading goggles of the halfway point of the season has the Padres as less favorable +110 choice to win the NL West compared back in March when they +600.

One element of James’ work that is as fresh today as it was when he first brought up new topics is the runs scored vs. runs allowed aspect of the game. If you score more runs than your opponent, you cannot lose. If you score a great deal more runs then the opposition, then you might have a dominate team. From the wagering standpoint, the value in this information is which teams are playing to their potential, which are playing above their potential and which are playing below. The last two elements are especially valuable, since if a team or teams continue on the same path, ultimately, they should reach their water mark and play accordingly.

Our goal in making long and short term wagers for baseball is to ensure equal representation of all teams. Since we have the time at the All-Star, we’ll look who at every Major League squad has played thru 81 games or half the schedule. This presents a balanced look at all the teams.

How this exercise works is to multiply the number of runs scored and square it, followed by doing the same with number of runs allowed. We’ll use the New York Yankees as the example.

Yankees runs scored – 436
Yankees runs allowed – 340

436 x 436 = 190096
340 x 340 = 115600

Add the two numbers together and divide the runs scored into the total to achieve a percentage.
190096 + 115600 = 305696
190096 divided by 305696 = .621

Take the number 81 (half the season) and multiply by .621, this gives you a total of 50.3. What this means is the Yankees should have a record of 50-31, based on runs scored and allowed and their actual record was exactly the same, thus right on schedule.

Any difference greater than three games means something is occurring that needs to be understood. Typically, bullpen production or lack of it is the biggest culprit in terms of wins and losses. Below is the complete list showing each team’s actual record and record based on RS/RA methodology and projected season total if they were to play exactly the same way.

American League (actual – projected- possible season record)

AL East
New York Yankees 50-31 - 50-31- 100-62
Boston 49-32 - 47-34 – 94-68
Tampa Bay 48-33 - 51-30 – 102-60
Toronto 41-40 - 44-37 – 82-80
Baltimore 25-56 – 25-56 – 50-112

AL Central
Detroit 45-36 – 41-40 – 82-80
Minnesota 44-37 - 46-35 – 92-70
Chicago WS 43-38 - 41-40 – 82-80
Kansas City 36-45 - 37-44 – 74-88
Cleveland 32-49 - 33-48 – 66-96

AL West
Texas 48-33 - 48-33 - 96-66
L.A. Angels 45-36 - 40-41 – 80-82
Oakland 40-41 - 40-41 – 80-82
Seattle 34-47 - 32-49 – 64-98

AL Observations – The biggest surprise out of the AL East is Tampa Bay projected to win its division. Though most sports books still taking action on division titles have the Rays as the third choice to win AL East, Tampa Bay brings plenty to the party. How they have managed to overachieve thus far is because they have the highest save percentage in the league and concede the lowest on-base percentage in the junior circuit (.305). Another reason Tampa Bay might be around longer than most expected is 25-10 record in games decided by four or more runs, showing their dominance.

The Detroit Tigers bullpen has saved them in the first half of the year, however their pitching as a whole might well send them plummeting in the second half of the season unless they swing a trade for another starter. The Chicago White Sox are the hottest team in baseball with an eight-game winning streak, but have to find a way to replace Jake Peavy who is gone for the year.

The Los Angeles Angels limp into the break having lost eight of last 10. Normally, if a team outperforms its RS/RA numbers, the bullpen is the reason. The overall season numbers for the Halos bullpen is meager, however during their hot June (19-10), the pen actually pitched well. Unless they pick up another bat for the lineup and the entire pitching staff improves, the Texas Rangers could well run away with this very weak division.

National League (actual – projected - possible season record)

NL East
Atlanta 48-33 - 48-33 – 96-66
N.Y. Mets 45-46 - 46-35 – 92-70
Philadelphia 43-38 - 46-35 – 92-70
Florida 38-43 - 43-38 – 86-76
Washington 35-46 -35-46 – 70-92

NL Central
Cincinnati 46-35 - 45-36 -90-72
St. Louis 44-37 - 47-34 -94-68
Milwaukee 37-44 -38-43 - 76-86
Chicago Cubs 35-46 -36-45 – 72-90
Houston 32-39 - 26-55 – 52-110
Pittsburgh 29-52 - 20-61 – 40-122

NL West
San Diego 48-33 - 47-34 – 94-68
L.A. Dodgers 45-36 - 43-38 – 86-76
Colorado 43-38 - 44-37 – 88-74
San Francisco 41-40 – 44-37 - 88-74
Arizona 32-49 – 32-49 – 64-98

NL Observations – The two-time defending NL champion Phillies have outperformed their record, thanks to their ability to rule the NL Central. Philadelphia is 17-8 and +39 in RS/RA against that division (+48 overall). With no Chase Utley likely until September, the Phillies might not have enough hitting or pitching to catch Atlanta. The Florida Marlins numbers suggest they should be better, which is why manager Fredi Gonzalez was shown the door. The Fish are tied for the most blown saves in the NL and their 11-17 record in one run games speaks volumes.

The NL Central appears to be a two team race the rest of the season and how they perform against the other four mediocre clubs should determine the Reds or Cardinals fate. If skipper Tony LaRussa can find ways to score more runs, St. Louis should win division based on numbers.

It’s interesting to note both Houston and Pittsburgh have out-performed (at least on some level) their actual RS/RA figures. Not sure what hiring former Astros star Jeff Bagwell as hitting coach is going to do for team that is 9-28 in games decided by four or more runs. Then there are the Pirates. Consider Pittsburgh has been outscored by 194 runs this season. To put that number into perspective, that is more than fellow last place teams Seattle and Arizona combined (-179 total). The Bucs are a walking play against run line team, losing by 2.2 runs per game and are 4-29 in contests determined by four runs or more.

San Diego is not a fluke, perfectly built for their vast acreage called Petco Park, with more than enough pitching to keep them competitive on the road. Will the lack of offensive production hold up, we’ll find out. Based on first half play, if one team in the NL West could improve, the San Francisco Giants should if they could squeeze more out of their batting order.

Base Hits can lead to Big Profits

While going thru Bill James 2010 “Gold Mine” book, came across statistical information that only baseball nuts would enjoy.

Part of James wisdom is taking something simple and applying it in common sense manner. For example if you score more runs than your opponent you will win 100 percent of the time. Pretty straight forward.

The article went on to talk above the value of base hits. No discussion of home runs, doubles, walks or even on-base percentage, just hitting the ball where the fielder cannot catch it.
Last season if you take away the all games that each team had the same number of hits in a ballgame; the final record was 1,766-433, a winning percentage of .803 for the club with more base hits in a single contest.

The light bulb switch went on in my dome and I started to wonder how this plays out for wagering purposes.

Pulled out all 30 teams’ home games (no reason to road contests since it’s the same) and looked to see what kind of profits are to be found in this fact-finding mission.

The most obvious aspect uncovered is there is a lot of money to be made by correctly determining the team that will have the higher amount of hits.

In the National League, teams with most base knocks are 105-34, 75.5 percent this season (thru 4-27). This generates a profit of +70.05 units. It goes without saying nobody is going to wager on every baseball game every day, still not many systems of any kind are going to yield these sorts of profits looking at each contest. How this ends up being such a money-maker is of the 105 wins, 37 were underdogs, help building the bankroll.

In the American League, the news is even better despite fewer games because of two less teams. Here we have an overall record of 89-25, 78.0 percent, yielding a handsome profit +70.25. Once again a healthy number of underdogs were part of the equation, as 36 of 89 winners were not favored. (Tampa Bay 12-1 when they outhit opposition)

In the interest of disclosure, this sample is just from April and no real way to know if these profits would hold up over a whole season, but based on “Gold Mine’s” findings, no reason to believe they shouldn’t.

Our next step is identifying how one could determine what teams will out-hit their opponents. Let’s start with taking swings at the dish.

Major League clubs that are near or above the median levels of batting average and have three or more games with nine or more hits have to be considered a play on team. When teams have this many base hits consistently, that probably means three players in the line-up are stroking it and as is the case of most hitting streaks, they can go along for about a week seeing the ball really well.

Conversely, when teams are totaling six or fewer hits for a few outings, this might be the time to play against them since they are likely swinging at pitcher’s pitches and being less selective, getting themselves out if you will.

Another factor is once a series of events has occurred, there is likely to be a reaction to them. Much of this is following detail. On April 17, the San Francisco Giants destroyed the Dodgers 9-0. Over the next seven games they total 11 runs and had a stretch of four games in the middle section where they had seven or fewer hits four times. In the last contest of the seven, they were shutout 2-0 by Brad Penny and the Cardinals, but showed signs of breaking out of slump with nine hits.

No question conventional wisdom would have suggested San Francisco would have a difficult time with Roy Halladay in town in next outing, however in the bigger picture, Jonathan Sanchez of the Giants had permitted 11 hits in 19.3 innings and Philadelphia had been outhit in all three games in Arizona. If you saw this entire view, the Giants at +135 home underdog becomes far more attractive and they won 5-1.

Another example of finding value with teams swinging the lumber was Baltimore on Tuesday night. The Orioles have the worst team in the Major’s and their most recent streak had reached five straight losses playing in Boston.

Baltimore started to show signs of coming out of this deep slumber with back to back nine hit games, though they only totaled four runs. After those two games they had 17 players hit their way on base, but lost 7-6 this past Saturday. That was three strong days hitting the baseball and they finally broke into the win column as +140 underdogs with 7-6 triumph, ripping 14 more hits.

It certainly would take a strong cup of courage, but here the O’s stood at 3-16, playing at home where they had not won a game (0-6) this season and were +155 underdogs to the Yankees.
However, weigh these elements. Baltimore was swing hot bats, they wanted to win at home against a tormenting team and despite their starter Kevin Millwood having 0-3 record, he had a 3.38 ERA going in the contest as his teammates had scored eight runs in his four starts in 2010. The Birds were outhit 9-7 by New York, but their increased patience at the dish produced six walks and the O’s were a very rewarding 5-4 winner as large ML pooch.

The other area to consider is the pitchers. This is a more complicated discussion because of the variables.

Hurlers that allow fewer hits than innings pitched and have modest walk totals are good wagers, especially with above average strikeout to walk ratios.

Starting pitchers that keep the hits down and have a history of being successful on the road are a terrific value as underdogs or small favorites. Pitching matchups also lend themselves to winning.

Any sports bettor loves an ace vs. a No. 5 starter, unfortunately that comes at a cost, namely a high money line. If the team’s No. 1 guy is backed by his club smacking the horsehide when he’s on the mound, the run line becomes more attractive option.

Better value can often be found when the No. 2 or 3 starter is facing a worst starting pitcher on the other team and as long as the presumed favorite is in good form and the better pitcher is not slumping, this too can be a smart wager.

There are many other scenarios, but one last important aspect to think about is the bullpen. Everything can be in order, yet a lousy bullpen with gruesome ERA and a vast number of blown saves can turn winners into losers quickly, be cognizant of this material.

To wrap this up, hitting the ball around the yard can lead to more winners than you thought possible. Stay current with the numbers and you can build your bankroll more rapidly.

One final bit of information from James book. When a team outhits the other by nine or more coming into this season, they are 197-0 all time.
