A different take: favorite player to wear a specific non-retired number:
#2: I did have irrational like for both Doug Griffin and then Jerry Remy. And a very rational like for Ellsbury. But I'm rooting for Xander to be the best wearer of this number.
#3: A black hole number since the days of Jimmy Foxx. Favorite has to be Mike Lansing...correction, make that David Ross for the 2013 playoffs.
#5: Nomahh. With an honorable mention to the Boomer.
#7: Quite a few notables since the days of Dom Dimaggio: Reggie Smith, JD Drew and brother Stephen, Nick Esasky (tragic), and, of course, Steve Lyons. But Trot was one of those that broke the Curse, so he wins.
#10: Another whole lot of suck in the number once proudly worn by Rick Lancellotti. But the pre-1986 Rich Gedman was pretty awesome until injuries derailed his career.
#11: Close call between Clay Buchholz (for both 2013 and the no-hitter) and Bill Mueller, but Mueller gets the vote for The Single in 2004.
#12: Also worn by Steve Lyons. And Will Cordero. Really, really close call between Mark Bellhorn and Mike Napoli, with the edge to Bellhorn for 2004. Honorable mention to Ellis Burks during his first go-around here.
#13: Only 3 players wore this number before Reid Nichols in 1985, and has since proven to be relatively unlikely (Hanley and Carl Crawford say hello). I'll give it to Alex Cora.
#15: Wow. We had Sparky Lyle wear this number as a rookie. Cecil Cooper before he was traded. George Scott in his encore. Mark "The Original Thanks Dad!" Sullivan. And "Batting second, #15, Craig Grebeck". This one is ultimately close, as Millar should always be known for Drawing the Walk that changed history, but still need to give the honors to Pedroia.
#16: Haywood Sullivan's old number. Since worn by the likes of Kevin Romine and Bob Zupcic. Jim Lonborg gets my vote for bringing us 1967 (a season for which I was too young to notice).
#17: Tie between Manny Delcarmen, Marty Barrett, and Cecil Cooper.
#18: Victorino and Dice-K each had important roles in the 2013 and 2007 playoffs. But Johnny Damon gets my vote.
#19: Yes, Koji threw the final pitch of 2013, but Fred Lynn in 1975 was one of those "you had to be there" moments.
I'll add more if/when I get the time.
