PHILADELPHIA — The Phillies made moves to restructure their bullpen Sunday, removing Taijuan Walker from the rotation and recalling right-handed reliever Seth Johnson before their series finale against the Milwaukee Brewers.

Mick Abel will take Walker’s place in the starting rotation Thursday in Toronto. Reliever Jose Ruiz was designated for assignment to clear a roster spot for Johnson.

“I think Tai’s got a chance to make us a lot better coming out of the ‘pen,” manager Rob Thomson said.

Walker has made 10 appearances, including eight starts and two long relief appearances, with a 2-4 record and 3.53 ERA in 43⅓ innings. Thomson will use Walker in one-inning roles.

The 32-year-old Walker has been primarily a starter throughout his 13-year career. He is in the third year of a $72 million, four-year contract.

Abel made his major league debut on May 18, throwing six scoreless innings. The 23-year-old was the No. 15 pick in the 2020 amateur draft.

Johnson, 26, is 2-2 with a 4.91 ERA and 42 strikeouts in 33 innings with Triple-A Lehigh Valley, transitioning from the starting rotation to a relief role. He made one appearance for the Phillies last year, allowing nine earned runs in 2⅓ innings on Sept. 8 against Miami.

Johnson was acquired by the Phillies from Baltimore on July 30, 2024, in a trade for Gregory Soto.

Ruiz had an 8.16 ERA in 14⅓ innings this season, including allowing five runs in one inning of Saturday’s 17-7 loss to the Brewers. The 30-year-old right-hander had a 5-1 record and 3.71 ERA in 52 appearances in 2024.
