Tyson Ross underwent arthroscopic surgery on his left (non-throwing) shoulder on Wednesday. Ross is expected to be 100 percent in time for spring training. The 26-year-old had a mini-breakout this season, posting a 3.17 ERA, 1.15 WHIP and 119/44 K/BB ratio over 125 innings. He figures to be a popular target in the late rounds of fantasy drafts next year.
