Guerra (1-0) struck out two in a perfect sixth inning Thursday to pick up his first win of the season in a 7-4 victory over the Phillies. The right-hander has been a solid part of the recent turnaround for the Nats' bullpen, posting a 2.35 ERA, 1.04 WHIP and 12:3 K:BB through 15.1 innings since being claimed off waivers from the Blue Jays. Guerra likely won't see much high-leverage work, limiting his fantasy appeal, but he's capable of providing useful ratios in deep formats.
Guerra was added to the Nationals' major-league roster Tuesday. It wasn't clear that there was a spot available for Guerra when he was picked up off waivers from Toronto on Monday, but the Nationals solved that problem by sending Jeremy Hellickson (shoulder) to the injured list. Guerra was perfectly adequate in his 14 innings for the Blue Jays prior to being designated for assignment, recording a 3.86 ERA.
The Nationals claimed Guerra on outright waivers from the Blue Jays on Monday, Mark Zuckerman of MASN Sports reports. The Nationals cleared a spot for Guerra on the 40-man roster by designating Dan Jennings for assignment. Since Guerra has a minor-league option remaining, he'll likely be assigned to Triple-A Fresno while the Nationals reserve Jennings' active roster spot to Tony Sipp (oblique), who was activated from the 10-day injured list. Over 11 appearances with Toronto this season, Guerra posted a 3.86 ERA and 1.21 WHIP in 14 innings.
Guerra was designated for assignment by the Blue Jays on Saturday. It was previously indicated Guerra was simply optioned to Triple-A Buffalo, but he was actually removed from the 40-man roster. The 33-year-old could still head to Buffalo if he goes unclaimed on waivers.
Guerra was optioned to Triple-A Buffalo on Saturday. He logged four innings in two appearances over a week up with the big club. The move clears a spot for Saturday's starter Ryan Feierabend.
