The Miami Marlins placed shortstop Tim Anderson on the 10-day injured list on Monday due to lower back tightness.

The move is retroactive to Saturday.

After spending the first eight seasons of his major league career with the Chicago White Sox, Anderson has struggled in his first season with Miami. He has hit just .197 with zero home runs and six RBIs in 36 games, striking out 38 times.

Anderson, 30, was a two-time All-Star with Chicago. He finished seventh in American League MVP voting in the COVID-shortened 2020 campaign and won the AL batting title in 2019 when he hit .335.

In another move on Monday, the Marlins activated left-hander A.J. Puk from the 15-day IL. Puk hadn't pitched since April 19 due to left shoulder fatigue, but he logged one-third of an inning during Monday's 6-5 loss to the host Detroit Tigers.

Puk, 29, is 0-4 with a 9.00 ERA this year.
