Jeff Sullivan has done a great job with collecting disabled list numbers. You can find his collected information here on the DL (edit-some of the datai is squirrelly and I used it as is. There needs to be some double checking on it). How does the AL East look?
The table above shows the total number of days on the DL spent by players of a specific organization as well as the total number of days spent by players who I deemed as significant losses. Those lists are certainly arguable:
Total Consequence Blue Jays 1431 228 Orioles 1381 109 Rays 987 200 Red Sox 1604 213 Yankees 1753 672
Blue Jays - Jose Bautista (77), Brett Lawrie (34), J.P. Arencibia (43), Brandon Morrow (74)I think the only teams where they may be some argument in whether or not I left out a player of consequence would be the Orioles and Red Sox. I am fairly confidant in those lists those. For the Orioles, Zach Britton and Nolan Reimold are missing. Britton's issues with control and Reimold's history (along with McLouth's emergence) cast doubt on how meaningful those absences really were. I'm not sure Britton's absence is all that much different from the Blue Jays missing Dustin McGowan or the Rays missing Jeff Niemann and Jeremy Hellickson.
Orioles - Nick Markakis (38), Jason Hammel (54), Mark Reynolds (17)
Rays - Evan Longoria (98), B.J. Upton (17), Desmond Jennings (24), Jeff Keppinger (34), Matt Joyce (27)
Red Sox - Jacoby Ellsbury (90), Cody Ross (31), Dustin Pedroia (15), David Ortiz (77)
Yankees - Michael Pineda (183), Brett Gardner (160), Mariano Rivera (153), CC Sabathia (37), Andy Pettite (83), Alex Rodriguez (40), Ivan Nova (17)
For the Red Sox, I decided not to include Carl Crawford, John Lackey, Josh Beckett, Kevin Youkilis, and Felix Doubront. The first four names are big names and the last is a younger player who shows good potential. However, I think there is a good argument to suggest that these players may not have added much to the team. I am still a Carl Crawford believer (though not at that money) and the Yankees think Youkilis is a good player to have around (evidenced by the contract he received for the upcoming year).
Back to the table above, I think there are a couple ways to look at it. One, looking at the overall numbers, the Orioles appear to be not much different from the rest of the division on average (1431 days), so it is difficult to say they suffered extraordinary through DL visits on that point. When you look at the number of days lost to the absence of players of consequence, the Orioles actually appear quite lucky in comparison to the other teams. If you add in Reimold and Britton along with the other teams adding in their arguably marginal talent, you get the follow table for DL days:
The average above is 490 days. Again, nothing seems incredibly unique about the number of days lost to injury for the Orioles. Health alone does not seem to be something the Orioles suffered worse for than the other teams in the division.
Loose Blue Jays 411 Orioles 447 Rays 324 Red Sox 594 Yankees 672
In the end, I think the hope for next year is that somehow two months of play from Chris Tillman, Miguel Gonzalez, Nate McLouth, and Manny Machado will somehow be extrapolated over the course of an entire season. If that happens, it adds about 8 or 9 wins to the team. So, yes, if you believe those four are real and the performances of the others on the team can be repeated as well as the club not suffering more significant injuries than they suffered last year (as opposed to the Rays, Blue Jays, Yankees, and Red Sox who lost top tier elite players over large swaths of the season)...then, yes, the Orioles could repeat their success seen in 2012 for 2013 without fortune smiling on them in one run games.
