Minutes before first pitch, pitching coach Chris Fetter emerged from the dugout and checked in with manager A.J. Hinch, exchanging the lineup card at home plate. Off in the distance, however, righty reliever Will Vest was warming up in the bullpen.
Manning, 24, missed Wednesday’s start with arm fatigue sustained in warmups. The severity of his injury is unclear, but the Tigers called the decision to scratch him a “precautionary move.” He will be further evaluated after the game.
Five pitches into Vest’s start, the right-hander allowed a leadoff home run to Kansas City Royals catcher MJ Melendez. He threw 19 pitches in the first inning and was replaced by left-hander Daniel Norris for the second inning.
Manning has made 10 starts since Aug. 2, when he returned from the injured list.
He had been on the injured list since mid-April because of right shoulder inflammation and needed two throwing programs and rehab assignments before regaining full health. Fellow young pitchers Casey Mize (Tommy John surgery) and Tarik Skubal (flexor tendon surgery) are out for the season with elbow injuries.
In 2022, Manning has a 3.43 ERA with 19 walks and 48 strikeouts over 63 innings in 12 starts. The Tigers drafted him with the No. 9 overall pick in the 2016 draft. He reached the big leagues for his debut in June 2021 and received 18 starts last season.
He has 30 starts and a 4.79 ERA in his MLB career.
