WASHINGTON (AP) — The Milwaukee Brewers placed outfielder Jackson Chourio on the 10-day injured list Friday after evaluations of his strained right hamstring revealed more significant issues than expected.

Chourio was injured Tuesday while running the bases on a triple in the fifth inning. The move to the IL was made retroactive to Wednesday.

Milwaukee manager Pat Murphy said the 21-year-old Chourio will likely require more than a minimum stay on the injured list.

“It won’t be anytime soon,” Murphy said before the Brewers’ series opener against Washington. “He was diagnosed a little more severely than we initially thought. To what extent, I’m not exactly sure. Nor are they. We’re just going to have to rehab it.”

Murphy said Chourio will receive a platelet-rich plasma injection.

Chourio is hitting .276 with 17 homers, 67 RBIs and 18 steals for Milwaukee, which entered Friday with the best record in the majors at 64-44. He was replaced on the active roster by outfielder Brandon Lockridge, who the Brewers acquired Thursday from San Diego for pitcher Nestor Cortes, infielder Jorge Quintana and cash.

Lockridge, who hit .216 with five RBIs in 47 games with the Padres this season, was inserted into the leadoff slot Friday against the Nationals. The Brewers won 16-9.

Milwaukee’s other move Thursday was to acquire pitchers Shelby Miller and Jordan Montgomery from the Arizona Diamondbacks for a player to be named or cash. Although Montgomery is recovering from Tommy John surgery and won’t pitch this season, Miller should play a key role in the Brewers’ bullpen once he comes off the injured list.

Miller, 34, last pitched on July 5 and is recovering from a right forearm strain. He is 3-3 with a 1.98 ERA and 10 saves in 37 appearances this season.

“I spoke to him earlier, and he said he feels great,” Brewers President of Baseball Operations Matt Arnold said. “That’s obviously music to our ears. … My guess is we’re going to get him in, get him evaluated and hopefully maybe a quick rehab assignment, and then hopefully he’ll be able to help the big league team very soon.”

Picking up part of Montgomery’s salary enabled the Brewers to acquire Miller without giving up a player.

In other moves, the Brewers designated left-hander Bryan Hudson and right-hander Elvis Peguero for assignment.

Hudson, 28, was 0-1 with a 4.35 ERA in 12 appearances for Milwaukee and 2-1 with a 6.84 ERA in 25 games with Triple-A Nashville this season. He went 6-1 with a 1.73 ERA for Milwaukee last year.

Peguero, 28, went 0-0 with a 4.91 ERA in six games for Milwaukee and 3-2 with a 3.55 ERA in 27 games for Nashville this year. He had a 3.38 ERA in 59 appearances for Milwaukee in 2023 and a 2.98 ERA in 52 games last season.
