I’ve never done a set of preseason predictions based on statistical analyses before, at least not on any real scale. There are so many questions when you start, not the least of which being “Whose stats do I even include??” A quick look at three random teams’ statistics from 2008 shows an average of 33 batters per team, combining for an average of 5,524 at-bats. Some of those players began the season in the minor leagues. Some began the season – or ended it – on completely different teams. Or on the DL.
Because none of these things can be predicted, I realize that trying to project a Major League Baseball season in early February is a bit… er… “ambitious,” let’s say. But I wanted to do it anyway, so I felt the need to establish some ground rules.
The methodology employed was fairly simple. I predicted a 25-Man roster for each team, based on offensive performance, but bearing actuals in mind, as well. For instance, though Jason Kendall ranked #3 on my list of Brewers catchers behind Vinny Rottino and Jesus Salome, I fully realize that he will be the starting catcher in Milwaukee.
The 25-Man rosters included starters and five bench players – including a catcher, two outfielders, and two infielders who could – at the very least – combine to play all infield positions. I then calculated the Runs Created for the roster (starters, bench players, and starting pitchers), based on the players’ statistics from the past three seasons. To create a uniform number of games played, I then broke this into RC27 and multiplied by 162 to get the Projected Runs for the season.
To project Runs Allowed, I broke down the pitching staff (12 pitchers, including five starters and a closer) using statistics from the previous three seasons, and calculated BaseRuns. I then used 1458 (162 games x 9 innings) divided by IP to create a multiplier for the BaseRuns projection, which I then used to project Runs Allowed.
Then, I used the Pythagorean Theorem (with a multiplier of 1.81) to determine an expected W-L%. Simple enough, but there are some issues with my methodology:
1) Because I am multiplying all statistics for minor leaguers, rate statistics will remain largely unchanged. For instance, if a player had 100 hits in 300 at-bats at the AAA level, he was a .333 hitter. In multiplying both hits and at-bats, he becomes 75/225 – still a .333 hitter.
2) Players are not currently weighted as starters and backups. At present, I am only weighting by average number of games over the past three seasons, adjusted for level. For instance, J.R. Towles is listed as the Astros’ starting catcher, but only receives 211 AB in 65 games. Quintero, his backup on my list, is credited with 230 AB in 75 games. This is also true of starting pitchers and relievers in terms of innings pitched. This is somewhat offset by adjustments on team totals – I used RC27, multiplied by 162, to determine Runs Scored, and multiplied team runs allowed to cover 1458 IP (9*162) to determine Runs Allowed. Teams are now evaluated as a unit. In the future, I would average the number of at-bats per position in the division and do a similar adjustment for individual players.
3) The likelihood of one 25-man roster playing for an entire season is practically nil. Because roster moves are tough to predict, I’m content simply to allow this for now.
4) 25-Man rosters were chosen by me, using a few factors. First, I went with the most offensively-sound possibilities, using my own analysis, with some consideration given to actuals. For instance, despite Jason Kendall’s projections falling third of the four Brewers catchers I projected, I know he will be the Opening Day starter, and so I have slotted him into their roster. I used whatever information I had available, which is incomplete at times. Where Rule 5 draftees are concerned, I did my best to predict who would make the roster, and who would be returned. This is subjective, though a lot of attention was paid to the projections. Additionally, I included at least one left-hander for all bullpens, even if that weakened the bullpen overall.
Since the methodology is consistent from team to team, for now I am content with it. At the end of Spring Training, once rosters are set, I will do a new set of projections with some adjustments to my method.
