"My arm was still recovering from my start, and I was able to throw my pen," Scherzer said. "But after that, I lost my range of motion that I had gained by loosening it up."
Scherzer has been dealing with shoulder fatigue since a Sept. 18 start against the Oakland Athletics. The ailment forced him from that appearance after only two innings, and it impacted him Sunday when he pitched against the Minnesota Twins.
Scherzer told reporters that he was pain-free for Sunday’s start, but he aggravated his injury during a side session on Tuesday. On the season the right-hander has posted an ERA of 3.82 over 31 appearances with a league-leading 11.2 strikeouts per nine innings compared to 2.8 walks per nine innings.
The Tigers have announced that Drew Smyly will start in Scherzer’s place Friday in Minnesota. Scherzer’s next turn would come during the club’s regular season finale against the Kansas City Royals, but it’s unknown if the 28-year-old will be available at that time.
