Tyler Mahle's first pitch on Wednesday was a fastball that traveled only 86.6 mph. Nothing to worry about, though — his next three fastballs were clocked at 88, 89 and 90 mph.
"He always starts a little slow when it comes to velocity. I didn't think anything of it right away," catcher Gary Sanchez said. "But I did notice after that inning that his velocity [still] was a little down."
Rocco Baldelli noticed, too. The Twins have been closely watching Mahle since they addressed their shortage of reliable starting pitchers by sending three coveted prospects to Cincinnati two weeks ago for the righthander. He spent two weeks on the injured list in July because of the injury, and though he had allowed only eight hits and four runs in his first 12 innings as a Twin, the shoulder was not yet fully healed.
"Mahle's been battling his shoulder for a couple starts," said reliever Emilio Pagan. "He's a warrior."
But even warriors need velocity on the mound, and Baldelli and pitching coach Pete Maki were quick to notice that Mahle's fastball was still lagging in the 80s in the third inning. And when he began swinging his arms, an apparent attempt to loosen the muscle, Baldelli was quick to act, too.
"You saw him have a couple of movements where he was stretching something in his upper half and putting his arms up in the air, and moving a little bit. That was it," said Baldelli, who removed his starter with a 1-2 count on shortstop Maikel Garcia. "He was probably on the border of coming out of the game sooner than that."
After an initial exam, Mahle, who was not available after the game, was diagnosed with simply "fatigue" in his shoulder, but the 27-year-old righthander will undergo an MRI to make sure there is no structural damage.
"There was nothing acute bothering him. He had some general soreness, but didn't mention anything painful," Baldelli said. "He checked out relatively OK after coming out of the game. That being said, we're going to learn more today and probably in the next couple days."
