Twins pitcher Yohan Pino has been diagnosed with a minor strain of his ulnar collateral ligament, MLB.com reports.
Pino, who was optioned to Triple-A after Saturday's doubleheader, will be shut down for two-to-four weeks, and he's likely to miss the remainder of the season. If his season is over, he'll finish with a 5.07 ERA and 50:14 K:BB ratio in 60 1/3 innings over 11 starts in his rookie season.
