The Minnesota Twins have placed pitcher Pablo López on the 15-day injured list due to a strained right hamstring, retroactive to Wednesday. López has shown impressive form this season, holding a 1.62 ERA over three starts with a 1-1 record. In his absence, the Twins have called up right-hander David Festa from Triple-A St. Paul. Festa, who will take the mound against the Detroit Tigers, has struggled a bit in the minors this season with a 5.40 ERA. Last season, he appeared in 14 games for the Twins, earning two wins but struggled with a 4.90 ERA. The team's depth will be tested as they navigate this injury setback.
