CHICAGO (AP) — The Pittsburgh Pirates placed right-handed reliever Isaac Mattson on the 15-day injured list before Tuesday's game against the White Sox with right hip inflammation.

In a corresponding move, the Pirates recalled left-hander Brandon Eisert from Triple-A Indianapolis.

Mattson has no record with a 5.35 ERA in 38 2/3 innings over 38 games this season, his fourth in the majors and third with the Pirates. The 31-year-old Mattson, a product of the University of Pittsburgh, last pitched on Saturday against the Los Angeles Angels and gave up three runs on four hits in a 6-1 loss.

Manager Don Kelly said Mattson “needs some rest and rehab to clear up” his hip condition. The move was retroactive to Sept. 6

Eisert is 0-1 with a 6.23 ERA in nine games over 8 2/3 innings with the Pirates. He started the season with the White Sox, who traded him to Pittsburgh on July 11, along with infielder and 2023 first-round draft pick Jacob Gonzalez for left-hander Jaden Woods and future considerations.

Eisert has a combined record this season of 2-2 with a 6.00 ERA over 36 innings in 34 games.
