- I'll be using projected numbers for this. These projections were for players prior to the start of the 2012 season. I projected regular season statistics for wOBA and then determined the wRC on those projections.
- I am only doing this exercise for position players.
- I don't have projections for every player that hit the disabled list.
- Speaking of disabled list, the injury data only includes players placed on the disabled list. If a player was never placed on the disabled list, but out for an extended period of time, I won't have his injury information listed. Perhaps I'll have another article once I get the database updated with all injury information (day-to-day injuries).
- Thanks to Jeff Zimmerman for compiling the disabled list information.
- Number three comes into play for injuries after September 1. The rosters expand and some teams leave injured players on the roster.
- Finally, I did this as an experiment. I've had a few people eyeball the data on the Twitters, and had no complaints. It uses projected numbers, so please don't take this as the be-all and end all.
- As pointed out during a previous article on lineups, the Texas Rangers took the mentality "if it aint broke, don't fix it". You can see this with just 75 days of hitters on the disabled lit.
- Rays manager Joe Maddon is still a genius. His team led all of the big leagues in days lost to the DL by hitters with 775. However, thanks to good pitching and a little luck, he was still able to post a .523 winning percentage.
- Although the Minnesota Twins had a total of 53 days on the disabled list for hitters in 2012, the "true" amount of days lost is greater. They simply left injured players on the roster - see Denard Span.
Without getting too technical, I'll quickly explain how I arrived at the numbers. With these two factors, I was able to approximate how much time was lost to the disabled list.
- First, I took my projections prior to the 2012 season and calculated the wRC.
- Secondly, I reviewed the disabled list days to determine the actual number of games missed. Just because a player misses x number of days, he could actually be missing less game time than that (off days, etc).
Troy Tulowitzki sits atop the chart with a projected lost wRC of 72. He's obviously a valuable part of the Colorado Rockies, but it's worth noting that as a team in 2012, the Rockies had 780 wRC - good for fourth overall among major league teams. However, even if Tulo was healthy for an entire season, the Rockies pitching staff was so awful, it wouldn't have mattered.
The same could likely be said for Jacoby Ellsbury
and David Ortiz of the Boston Red Sox. Both players alone combined for 91 lost wRC. However, even if they were healthy, the pitching staff and team in general, had their fair share of problems.
Ryan Howard and Chase Utley would have combined for 77 lost wRC. Considering both players missed a majority of the first half a season, it's easy to see why the team struggled offensively early on, but started to pick up steam during the second half of play.
I have more players for the list, but only included 25 significant players as a "BETA" test. If you want to see another player, just drop me a line.
