Pittsburgh Pirates

Ryan O'Hearn

RF

O'Hearn had to be helped off the field Friday after tweaking his quad while running to first base, and he's expected to remain on the shelf for roughly 6-to-8 weeks after being diagnosed with a strain. His initial timeline leaves room for him to return during the final weeks of the regular season, but the Pirates could elect to keep him out for the rest of the year depending on where they sit in the race for a postseason berth when he gets close to being fully healthy. Until then, Jacob Gonzalez figures to see more time at first base, and Rafael Flores (concussion) will come off the IL to fill the open roster spot.

Evan Sisk

RP

Sisk has been shelved for the past month with left elbow inflammation, but he's progressed enough to pitch in games again. The southpaw reliever was terrific out of the Pirates bullpen before getting hurt, collecting a 2.23 ERA, 1.18 WHIP and 43:13 K:BB in 36.1 innings.

Oneil Cruz

CF

Cruz is finally trending in the right direction as he continues rehabbing a fractured left hand. The Pirates anticipate the center fielder getting in some live at-bats later this week or early next week before heading out on a rehab assignment shortly thereafter. Cruz is eligible to return from the 60-day injured list Aug. 7, and he could be ready to go on or around that date if all goes well. Jake Mangum has been filling in as the Pirates' everyday center fielder since Cruz went down, but he will revert to fourth-outfielder duties once Cruz is back in the fold.

Chris Devenski

RP

Devenski has been sidelined since early May due to an undisclosed illness, but he's finally been cleared to participate in games. Given the length of his absence, the veteran reliever will likely require a handful of rehab outings before rejoining the Pirates' active roster.

Konnor Griffin

SS

Griffin was given an 8-to-10-week return timeline when he landed on the injured list Tuesday with a torn tendon in his left ring finger, so the Pirates will stash him away on the 60-day IL, ruling him out until at least Sept. 4. The move opens up a spot on the 40-man roster to help make room for Brandon Eisert and Jacob Gonzalez, both of whom were acquired in a trade with the White Sox on Friday.
