MINNEAPOLIS -- Closer Glen Perkins is scheduled to be checked by team doctors on Thursday, as the Twins are concerned about a dip in his velocity and his recent struggles.
Perkins, who missed time earlier this month with a stiff neck, will undergo an MRI on his left arm to examine his forearm, elbow and biceps, general manager Terry Ryan said. The left-hander has a 13.50 ERA in six appearances in September, and he gave up a go-ahead three-run homer to the Tigers in the ninth inning of the Twins' eventual 4-3 win on Tuesday.
"There's nothing I can tell you until he's seen," Ryan said. "They're going to give him a complete look. We'll wait until we hear the complete diagnosis, and then we'll make a call. We don't want to be premature here."
Perkins talked with manager Ron Gardenhire after his blown save on Tuesday and indicated that something is off. Perkins, whose fastball has averaged 93.4 mph this season, was throwing in the low 90s on Wednesday, according to Fangraphs.com.
"Perk came in and said he didn't feel great last night," Gardenhire said. "He's had that thing in the neck. We're going to get him checked out. With the velocity going down like that, it's best to let the doctors tell us where we're at."
With Perkins out, right-hander Jared Burton will serve as closer.
