MIAMI -- Nationals manager Matt Williams announced Tuesday that Ross Detwiler will have a bigger role out of the bullpen, while fellow left-hander Jerry Blevins will be more of a specialist.
Detwiler started the season as just a long reliever, but he has pitched well enough to throw in the late innings. In his last 10 games, the southpaw has a 1.23 ERA, while opponents are hitting .146 against him.
"Det has really come on and pitched well -- right or lefty -- with the exception of last night, when he gave up a couple of hits," Williams said. "You never know what might present itself. It depends on that day and who's available and who's not potentially."
When the Nationals acquired Blevins from the Athletics, he had a reputation of getting lefties and righties out. But so far, right-handed hitters are 23-for-83 (.324) against him, while lefties are 8-for 66 (.121). The emergence of Detwiler has given Blevins a more specialized role.
"If we look at that, we would love to get [Blevins] in some lefty situations," Williams said.
