The Rangers have purchased the contract of left-hander Sam Freeman from Triple-A Round Rock and designated right-handed reliever Stolmy Pimentel for assignment, executive VP of communications John Blake announced (on Twitter).
The 25-year-old Pimentel has worked to a 3.97 ERA with a 7-to-3 K/BB ratio in his 11 1/3 innings with the Rangers since being claimed off waivers from the Pirates. Despite the lack of punchouts, Pimentel sports a swinging-strike rate of 10.9 percent this season and 12.9 percent in his career — both of which are considerably higher than the league average of about nine percent. He’s also racked up a 48.6 percent ground-ball rate and averaged 92 mph on his heater (though that mark is admittedly down from his 2014 average of 93.3 mph), making him a relatively intriguing bullpen piece for teams looking for middle relief help.
In a small sample of work this season, Pimentel has showed a pronounced platoon split, yielding a .443 OPS to righties but a 1.071 OPS to lefties (again — in just 14 plate appearances). His splits have been less notable throughout his brief, 53 1/2 inning Major League career, however. I’d imagine that Pimentel will generate some interest from other clubs in the 10-day window that Texas has to trade him or attempt to outright him to Triple-A.
