Pirates director of sports medicine Todd Tomczyk confirmed Wednesday that Cahill was placed on the 10-day injured list over the weekend after aggravating his left calf strain, Kevin Gorman of TribLive.com reports.

EDGE Analysis

The same injury kept Cahill on the shelf for nearly three weeks before he returned to action June 10. He was active for only two days before suffering the setback, and given the recurring nature of his injury, Cahill could be looking at a longer recovery period this time around. Even before Cahill aggravated the calf injury, the Pirates had already pulled the plug on him as a starter and shifted him to a long-relief role, so he'll likely work out of the bullpen once activated.

Cahill was placed on the 10-day injured list Saturday with a left calf injury.

EDGE Analysis

He most recently logged 1.1 scoreless innings while walking three and striking out three Friday in Milwaukee, and he apparently suffered the injury during that appearance. Geoff Hartlieb was recalled to take his place in the bullpen.

Pirates manager Derek Shelton confirmed after Thursday's 6-3 loss to the Dodgers that Cahill will work out of the bullpen for the "immediate future," Jake Crouse of MLB.com reports.

EDGE Analysis

Pittsburgh appears content to proceed with Chase De Jong as its fifth starter for the time being, so the team won't have a rotation spot available for Cahill, who returned from a three-week stay on the injured list earlier Thursday. Shelton said he wouldn't rule Cahill out from rejoining the rotation at some point, but it will likely take an injury or poor performance from another starter before the 33-year-old gets an opportunity.

Cahill (calf) was reinstated from the 10-day injured list Thursday.

EDGE Analysis

Cahill spent just under three weeks on the injured list with a left calf strain, but he's been facing live hitters recently and has built up his pitch count. Manager Derek Shelton has acknowledged that the Pirates may not have a rotation spot available, so the right-hander could be used as a long reliever in the near future.

Cahill (calf) completed another throwing session at PNC Park on Sunday, Jason Mackey of the Pittsburgh Post-Gazette reports.

EDGE Analysis

According to MLB.com, Cahill threw a live batting practice session June 1 that consisted of about 30 pitches, and he's continued to steadily build up his count since then. Though Cahill is getting stretched back out for a potential starting role, Pirates manager Derek Shelton acknowledged that the team may not have a rotation spot available for the 33-year-old once he returns from the 10-day injured list, per Rob Biertempfel of The Athletic. Cahill posted a 6.81 ERA and 1.49 WHIP across eight starts prior to landing on the injured list May 22 with a left calf strain.

Cahill (calf) completed a bullpen session Tuesday, Mike Persak of the Pittsburgh Post-Gazette reports.

EDGE Analysis

Cahill looks to be tracking toward a brief stay on the 10-day injured list due to his strained left calf, but the Pirates aren't expected to activate him when first eligible this weekend. If Chad Kuhl (shoulder) ends up beating Cahill back from the IL, the latter may not have a spot in the rotation waiting for him whenever he's reinstated.

General manager Ben Cherington said Sunday that Cahill (calf) , who was placed on the injured list Saturday, avoided serious injury, 93.7 The Fan Pittsburgh reports.

EDGE Analysis

"We don't think the injury is severe," the general manager noted. "We're going to give him a chance to feel better. Not sure exactly how long it's going to be. Shouldn't be too long." Cherington mentioned Miguel Yajure and Cody Ponce as possibly replacements for Cahill in the rotation.

The Pirates placed Cahill on the 10-day injured list Saturday with a left calf strain, Alex Stumpf of DKPittsburghSports.com reports.

EDGE Analysis

The move, retroactive to May 20, sidelines the righty until at least May 30. Cahill has made a few impressive starts this season, but his overall inconsistency has led to a 6.81 ERA in 35.2 innings.

Cahill exited Wednesday's start against the Cardinals with left calf discomfort, Jason Mackey of the Pittsburgh Post-Gazette reports.

EDGE Analysis

The 33-year-old is considered day-to-day, so it appears he's avoided a serious injury. However, Cahill's availability for his next turn through the rotation remains up in the air.

Cahill was removed from Wednesday's start against the Cardinals with an undisclosed injury, Kevin Gorman of TribLive.com reports.

EDGE Analysis

The 33-year-old issued two walks and hit a batter to load the bases during the second inning before exiting the contest with the athletic trainer. The right hander was charged with four earned runs while recording only three outs. It's unclear if the injury will affect Cahill's next turn through the rotation.
