The Rangers finally lost patience with Shawn Tolleson‘s struggles in the closer’s role. On Thursday, the club informed him he was being removed from the closer’s role, Jeff Wilson of the Fort Worth Star-Telegram reports. Sam Dyson will operate as the new closer going forward.

“It wasn’t anything that surprised me,” Tolleson said. The 28-year-old right-hander saved a league-best 11 games but sported an ugly 9.20 ERA with an 11/5 K/BB ratio in 14 2/3 innings. Tolleson’s ERA exploded when he allowed three runs in two-thirds of an inning on Saturday and when he gave up another four runs in two-thirds of an inning on Tuesday.

Dyson, meanwhile, entered Wednesday’s action with a 1.89 ERA and a 13/6 K/BB ratio in 19 innings. The 28-year-old was just as solid last season between the Marlins and the Rangers.

Despite the bullpen woes, the Rangers came into Wednesday afternoon at 22-18, just a game behind the Mariners for first place in the AL West.
