The Blue Jays designated Guerra for assignment Thursday. Guerra lost his spot on the active roster with the Blue Jays bringing fellow reliever Ryan Tepera (elbow) back from the 10-day injured list. Over his nine appearances with Toronto spanning 10 innings, Guerra struck out 12 batters but surrendered six earned runs on nine hits and four walks. If he passes through waivers unclaimed, Guerra is expected to stay in the organization and report to Triple-A Buffalo.
Guerra gave up two runs on a hit and a walk while recording only one out in Sunday's loss to the Rays. In two outings during the weekend series against Tampa, Guerra coughed up five runs on five hits and two walks over 1.1 innings, sending his ERA soaring from 1.35 to 6.75. The veteran right-hander remains in a low-leverage role for the Jays, notching only one hold in eight appearances, and he could be the roster casualty when Ryan Tepera (elbow) completes his rehab assignment.
The Blue Jays selected Guerra's contract and will include him on the Opening Day roster, Hazel Mae of Sportsnet reports. With fellow relievers Ryan Tepera (elbow) and David Phelps (elbow) opening the season on the injured list and non-roster invitees Bud Norris (forearm) and John Axford (elbow) also banged up, Guerra was able to earn a spot in the bullpen to begin the campaign. The veteran right-hander will likely be used primarily in lower-leverage spots.
Guerra gave up a hit and struck out one in a scoreless inning of relief during Wednesday's Grapefruit League game against the Braves. Signed to a minor-league deal in January, Guerra was something of a longshot to break camp in the Jays' bullpen until Ryan Tepera (elbow) and John Axford (elbow) both broke down this week. His major-league experience and solid spring (1.29 ERA, 6:3 K:BB in seven innings) might now put him in the mix for a middle-relief role if the club can find room for him on the 40-man roster.
Guerra signed a minor-league contract with the Blue Jays and will be among 15 non-roster players invited to big-league spring training, John Lott of The Athletic reports. There had been murmurs earlier this month that Guerra and the Blue Jays had agreed to a deal, but Toronto didn't acknowledge the signing until releasing its non-roster invitee list Saturday. The 33-year-old Guerra has 31 saves to his name in the majors, but he's mostly flitted between Triple-A and the big leagues for the better part of the past six years. Even if he earns a promotion to the 40-man roster at some point, Guerra likely wouldn't have much job security in the Toronto bullpen.
