found this on the net and very informative, interesting to say the least.....
WHY BETTING UNDERDOGS IN BASEBALL IS DIFFERENT FROM ANY OTHER SPORT.
There are several different approaches and strategies to handicapping baseball, but the most fundamental and obvious starting point is one that is taken completely for granted. Baseball is quite unique when it comes to betting because the gaps between the best and worst teams are far closer than in any other sport. Let's look at the other major betting sports.
In the NFL this season, the Indianapolis Colts were 14-2 winning 87.5% of their games. The worst team in the NFL this past season was the St. Louis Rams at 1-15, winning just 6.25% of the time.
In the NBA this season, Cleveland is currently 47-14 winning 77% of their games and Lakers are 45-15 winning 75% of their games. The worst team in the NBA is the New Jersey Nets at 6-53 winning 10.2% of the time.
In NCAA Basketball this season, Kansas, Syracuse and Kentucky are all 27-2 with a 93.1% winning percentage. The ?Board? team with the worst record in the country is Marist at 1-28, winning 3.4% of the time.
In NCAA Football, Alabama and Boise State both finished undefeated at 14-0 (100%) while Eastern Michigan and Western Kentucky both finished 0-12 (0%).
Meanwhile, the 2009 baseball season was not that much different than any other baseball season.
The New York Yankees had the best record in the majors last season at 103-59 (63.6%) and the Los Angeles Angels had the second best record at 97-65 (59.9%). The two worst teams in the majors were the Washington Nationals at 59-103 (36.4%) and the Pittsburgh Pirates at 62-99 (38.5%). These records are nowhere close to the best and worst records of any other major betting sport.
So there you have it:
Sport Best Worst
NFL 87.5% 6.25%
NBA 77.0% 10.20%
NCAAB 93.1% 3.40%
NCAAF 100% 0.00%
MLB 63.6% 36.40%
While it seems like an obvious point, it is often overlooked that the worst team in baseball still wins at a percentage well in excess of at least triple the worst team in any sport. Taking it a step further, based on last season's numbers, the worst team in baseball won slightly less than 2 out of every 5 games, while the best team in baseball won slightly more than 3 out of every 5 games. Let's face it, in NCAAB, if you put Kansas up against Marist 100 times this season, Kansas would probably win 99% of the time if not every time. In the NFL, if the Colts played the Rams 10 times, they'd easily win 9. In the NBA, if the Cavs played the Nets 100 times, they?d probably win close to 90% of the time. In college football, if Alabama faced Eastern Michigan or Western Kentucky 100 times, they would win at least 95% of the time if not every time. It's nothing like that in baseball.
In 2009, the worst team in the majors, the Washington Nationals, walked into Yankee Stadium and beat the best team in the majors, the New York Yankees 2 out of 3 times in June and showed a huge profit for the series (more than +5 units). The Houston Astros finished 74-88 (45.7%) but beat the National League Champion Philadelphia Phillies 6 out of 8 times and the team in the NL with the best record, the Los Angeles Dodgers (95-67, 58.6%) 4 out of 7 times. The Pittsburgh Pirates at 38.5% beat the Florida Marlins at (87-75, 53.7%) four out of six times and had a better record against the East Division (18-16) than did the Division Champ St. Louis Cardinals who were 17-16. The Mets were 25 games worse than the Dodgers but had a better record against the Central Division at 23-17 while the Dodgers were 22-19. The Phillies had a 6-12 Interleague record while the Pirates were 8-7. Anyone can beat anyone in baseball!
The point can also be further highlighted by looking at starting pitchers. Let say we?re back in March 2009 and I gave you the choice of Groups A or B below and told you that you had to bet one unit on each pitcher in each start for the 2009 season in the group you choose.
GROUP A:
Tim Lincecum
Zach Greinke
Roy Halladay
Johan Santana
Clayton Kershaw
Chad Billingsley
Ryan Dempster
James Shields
GROUP B:
JD Martin
Braden Looper
Kevin Correia
David Huff
Matt Palmer
Clayton Richard
Barry Zito
Sean West
Most people before last season started would?ve chosen Group A for sure. In fact, if I asked many people today (on March 3, 2010) to choose Group A or B as the better investment last season (after the fact), I still think most people would choose Group A.
Let?s look at the results:
GROUP A
Team Record Profitability 1 unit/gm
Tim Lincecum 19-13 -1.62 units
Zach Greinke 17-16 -5.07 units
Roy Halladay 17-15 -6.73 units
Johan Santana 13-12 -1.71 units
