The Miami Marlins bolstered their bullpen Friday by acquiring right-handed reliever Aaron Crow from Kansas City for pitchers Brian Flynn and Reid Redman.
Crow was 6-1 with a 4.12 ERA and three saves for the Royals last season, holding all batters to a .240 average and right-handers to a .215 average. But lefties hit .271 off him and he struggled after the All-Star break, going 0-2 with a 6.86 ERA.
Crow is 20-11 with a 3.43 ERA and six saves in 254 career appearances over four seasons. His 20 wins are tied for the second-most among American League relievers since 2011.
The Royals drafted him 12th overall in 2009. Crow made $1.5 million last season and is arbitration-eligible for the second time.
Flynn, a left-hander, was 0-3 with an 8.64 ERA in six career appearances for the Marlins. Redman, a decent prospect, was 7-3 with a 2.00 ERA in two seasons, mostly in the low-level minors.
