Impending free agent right-hander Colby Lewis underwent surgery Friday to repair a torn meniscus in his left knee. Rangers general manager Jon Daniels revealed the news in his season-ending press conference following the team’s exit from the ALDS.

According to T.R. Sullivan of, Daniels said that Lewis had pitched through the injury during the second half of the season. While the 36-year-old finished with a career-high 17 wins, he posted a 4.66 ERA (91 ERA+) and 142/42 K/BB ratio in 204 2/3 innings over 33 starts. He was used out of the bullpen for the ALDS against the Blue Jays.

Daniels confirmed Friday that the Rangers have interest in retaining Lewis for 2016.
