MLB 2009 Playoff Shifts

WEEK 6

AMERICAN LEAGUE
The clear-cut winner this week in the AL was the Texas Rangers who not only went 6-0, they swept two division rivals, including pre-season favorite Los Angeles. Division wins obviously make a major impact on a team's chances of winning the division, which obviously is a major factor in making the playoffs. The Rangers went from a 38% chance of making the playoffs to 55.5%.

In AccuScore's pre-season forecast the Toronto Blue Jays were forecasted for a respectable 83 wins which was only good enough for 4th in the AL East. But with the exception of Week 4, the Blue Jays have been in the Top 3 of this list as they continue to have the best record in the American League. The New York Yankees also had a good week going 5-1, including 2 road wins over the Blue Jays. A good week combined with a bad week for Boston helps the Yankees significantly close the gap with the leaders in the division. The Tampa Bay Rays were 4-2 this week, but actually lost a percentage point because their wins (3 over Cleveland at home, 1 at Baltimore) were games they were 'supposed to win.

The losers this week were the Boston Red Sox who were 2-4, which in most weeks would not be devastating, but when the Blue Jays, Yankees and Rays all have good weeks, it leads to a -15 percentage point drop. The Angels, Mariners, and Chicago White Sox are also all licking their wounds after going a combined 5-13 this week.

NATIONAL LEAGUE
The Milwaukee Brewers find themselves at the top of this list in the National League for the second straight week. Going 5-0 will do that for you. The only reason why the Brewers did not improve by 8 or 9 points is the fact that the Cubs also had a solid 4-1 week, which was good enough to improve their chances by 5 percentage points. When the Brewers and Cubs do well, you know this is bad news for the St. Louis Cardinals. A poor 1-4 week not only slashed the Cardinals' chances by nearly 15 percentage points it actually helped the Cincinnati Reds improve by 5 percentage points, who were a modest 3-3. The reason why the Reds improved more going 3-3 than the Cubs did going 4-1 was the Reds won road games. The Cubs went 4-1 in games where they were heavy favorites in all 5 games.

Juan Pierre is playing very well for the Los Angeles Dodgers and the team went 4-2 this week without Manny Ramirez. Even with the suspension the Dodgers are currently averaging the most wins in season simulations in the entire league. The Dodgers' success in the NL West is balanced by the poor performances by the San Diego Padres and Arizona Diamondbacks.

In the NL East, the Florida Marlins capitalized on an easy schedule in the first 2 weeks of the season to rush out to a lead in the division, but they have now come back to earth. Their 1-5 week resulted in the second biggest drop in the NL this week. The Philadelphia Phillies were 5-2 and you might have thought they would have improved their chances by more than 1.7 percent, but 3 of their wins were games they should win (Washington at home) and when faced with a quality opponent, they dropped 2 of 3 at home to the Dodgers.

OTHER TRENDS OF NOTE
Baseball fans should definitely review AccuScore's game-by-game simulations. AccuScore simulates every game one at bat at a time, 10000 times to generate the exact probability each team has of winning. So far this year, the team that won over 50% of simulations has won 57.3% of the time. You may not think that is some great number until you compare it to the percentage of time that Las Vegas odds-makers have correctly picked the winner - just 52.8% of Vegas favorites have won, a full 4.5 points less than AccuScore's simulation based forecasts.
