MINNEAPOLIS -- Right-hander Yohan Pino underwent an MRI exam after feeling some elbow discomfort during his start in Game 1 of Saturday's doubleheader, and he was diagnosed with a minor strain of his ulnar collateral ligament.
Pino came up as the club's 26th man on the roster for the twin bill and gave up four runs (one earned) over five innings to get his second career win. He was optioned back to Rochester after the game, but Pino reported that his elbow began to flare up during the third inning, and he will remain in Minnesota to be treated by the club's medical staff at Target Field.
He'll be placed on the Minor League disabled list instead of the Major League disabled list because he was technically sent back to Rochester after his start.
"They think it'll be two to four weeks before he's able to throw here," Twins assistant general manager Rob Antony said. "But as the 26th man, he has to go back. It's a stipulation as part of the Collective Bargaining Agreement he has to be DL'd at Rochester."
Pino was a candidate to return once rosters expand on Sept. 1 but could miss the rest of the season with the injury. Pino, 30, is 2-5 with a 5.07 ERA in 11 starts with the Twins this season. He also went 10-2 with a 2.47 ERA in 16 appearances, including nine starts at Rochester.
"He was tremendous in the Minor Leagues and handled himself up here," Antony said. "He competed and kept us in games."
