The Boston Red Sox' vaunted pitching depth is getting an early stress test.

Just days after placing Johan Oviedo on the injured list with a right elbow strain, the team announced Wednesday that right-handed reliever Justin Slaten is also headed to the 15-day IL (retroactive to April 5) with a right oblique strain. Slaten last pitched April 4 against the San Diego Padres. It's a tough loss for the Red Sox, as Slaten had been one of the bright spots on a hit-or-miss pitching staff. He had yet to allow a run in 3 1/3 innings out of the bullpen, across four appearances.

In Slaten's place, the Red Sox are calling up left-handed pitcher Tyler Samaniego from Triple-A Worcester. Samaniego, 27, has yet to pitch in the major leagues in his career. He is off to a solid start for the WooSox, with a 3.38 ERA in 5 1/3 innings over three total appearances.

On Oviedo, manager Alex Cora told reporters Wednesday that the righty has a flexor strain and will be shut down for at least six weeks.

The Red Sox are coming off a much-needed 3-2 win over the Milwaukee Brewers on Tuesday night at Fenway Park. They rebounded from a loss in the series opener both at the plate and on the mound. Garrett Crochet allowed two runs over 6 1/3 innings, while relievers Zack Kelly, Garrett Whitlock, and Aroldis Chapman combined for 2 2/3 scoreless innings. They have rarely lacked options for right-handed relief, but it's possible they feel the absence of Slaten at some point, if and when they're in a high-leverage situation late in a close game.

As of this writing on Wednesday, the Red Sox held a 3-0 lead over the Brewers during the fifth inning at Fenway. Sonny Gray got the start for Boston.
