Mark Buehrle: Wore 56 his entire career; 56 is available on the Jays.
Jose Reyes: Wore 7 his entire career; 7 is available on the Jays.
Josh Johnson: Wore 55 his entire career; 55 is available on the Jays.
Melky Cabrera: Wore 53 since 2009 with the Yankees, Braves, Royals and Giants. 53 is available on the Jays.
John Buck: Wore 14 since 2006 in KC, Toronto and Miami; 14 is available on the Jays.
Maicer Izturis: Wore 6 in Angels from 2005-2009 then changed to 13 from 2010-2012. 13 is taken by Lawrie but 6 is available on the Jays.
Emilio Bonifacio: Wore 1 since 2009 in Florida/Miami; 1 is available on the Jays. Also wore 4,6, and 7 when in Washington.
Bobby Wilson: Wore 46 from 2008-2012 but Evan held that number last season. Crawford is not a staple in the Jays pen yet so i assume Wilson my get 46 back.
Esmil Rogers: Wore 48 from 2010-2012 in Colorado but wore 32 last season for the Indians. Happ currently wears 48 but 32 is available on the Jays.
Jeremy Jeffress: Wore 41 with the Brewers and Royals. Sierra wore 41 last season; both guys are not expected to be on the 25 man roster so the number maybe up for grabs if whoever gets called up first.
