Phillies vs Padres

It's unclear how long Backhus' elbow has been bothering him, but he hadn't pitched since Saturday. Trevor Richards will assume his spot on the roster and in the bullpen.

Lazar has been out all season with a left oblique strain he suffered during the World Baseball Classic while playing for Team Israel. He is on the 60-day injured list and not eligible to return until late May, so Lazar will make several rehab appearances before the Phillies consider adding him back to their active roster.

Pop has been sidelined by a strained right calf since mid-April, but he's gearing up for his return to the Phillies. The right-hander will presumably need a handful of rehab outing before Philadelphia considers reinstating him from the injured list. Over 7.1 innings on the year, Pop has a 3.68 ERA, 1.09 WHIP and 6:3 K:BB while working mostly in middle relief.

The veteran slugger took Luis Severino deep for a solo shot in the third inning to open the scoring before launching a two-run homer off Tyler Ferguson in the eighth. Harper is locked in right now, racking up seven hits over the last three games including two doubles and three long balls to boost his slash line on the season to .286/.377/.571 with nine home runs, two steals, 22 runs and 23 RBI in 36 contests.

Marquez surrendered seven runs over five innings in his most recent start Friday against the White Sox and will now spend at least the next couple weeks on the IL. Griffin Canning (Achilles) was reinstated from the IL in a corresponding move and will take Marquez's spot in the rotation beginning with Sunday's series finale versus Chicago.

It has not been revealed when or how Cronenworth suffered a concussion. The veteran infielder has had a rough season thus far with an OPS of just .498 and a .077/.200./.077 slash line over the last seven days as of Tuesday. The Padres recalled Sung-Mun Song in a corresponding move.

It has yet to revealed how Campusano fractured his left toe. He had been hitting the ball well to begin the season, but was losing playing time to the better defender in Freddy Fermin. Fermin will likely continue to get more starts with Campusano on the injured list and Rodolfo Duran, who was selected from Triple-A El Paso on Thursday, serving as the backup catcher.

Per Annie Heilbrunn of the San Diego Sports Association, Stammen believes that Pivetta is looking at "weeks, maybe months" of rehab and rest. That kind of timeline indicates that Pivetta will be out of action until the summer, potentially through the All-Star break in mid-July. Matt Waldron (lower body) is slated to take Pivetta's spot in the rotation later this week once the former is activated from the 15-day IL.
