Chicago White Sox right-hander Carson Fulmer strained his right hamstring running the bases in the 14th inning Friday night and landed on the 10-day injured list Saturday.
Fulmer ripped a ground ball to third base in his first career at-bat but injured his leg while hustling down the line.
The White Sox went on to defeat the host Philadelphia Phillies, 4-3, in 15 innings.
Fulmer, 25, threw two scoreless innings before the injury. He is 1-1 with a 5.30 ERA and 20 strikeouts in 18 2/3 innings this season, spanning 14 games (one start).
Chicago recalled right-hander Dylan Covey from Triple-A Charlotte in a corresponding move.
Covey, 27, is 1-7 with a 6.99 ERA in 14 appearances (10 starts) with the White Sox this season.
