Sandy Rosario should be used to this by now.
The right-handed pitcher was claimed off waivers for the third time already this offseason, as the Cubs acquired the 27-year-old from the Red Sox. The move means the Cubs' 40-man roster is full, but with a couple months left in the offseason, that will likely change again.

Rosario signed with the Marlins as a free agent out of the Dominican Republic in 2004 and has appeared for the big-league club in FloridaMiami each of the past three seasons, sporting a 15.26 ERA and 3.26 WHIP in 10 games (7.2 innings).
He's been a much better pitcher in the minors, however. The 6-foot-1 righty has a 3.48 ERA and 1.32 WHIP in 157 career minor-league games, including 27 starts. He was especially good last season, boasting a 1.99 ERA, 0.98 WHIP and 17 saves in 31 games, 25 of which came at the Triple-A level.
