Cosart (elbow) cleared waivers and elected to become a free agent Monday.

EDGE Analysis

The Padres DFA'd the oft-injured pitcher earlier in the week, and Cosart decided to test the free agent market rather than stick around in San Diego's minor-league system. On top of his injury problems, the 27-year-old owns an unsightly 5.67 ERA, 1.79 WHIP and 53:58 K:BB over the past two seasons (81 innings), so he may have to start on a minor-league deal.

Cosart (elbow) was transferred to the 60-day disabled list Thursday.

EDGE Analysis

The Padres needed to clear a 40-man roster spot for reliever Kyle McGrath to come up to the big leagues, and given that Cosart is out for the year, he was a logical choice to cast off the 40-man. He underwent elbow surgery on July 19 and will now focus on getting ready for the 2018 season.

Cosart underwent arthroscopic surgery on his right elbow this week and will be out for the remainder of the season, Dennis Lin of The San Diego Union-Tribune reports.

EDGE Analysis

Cosart had been rehabbing at the team's spring training complex after being diagnosed with a flexor strain, but the injury appears to have required more of a long-term solution. The righty, who missed the beginning of the season while sidelined with a hamstring injury, finishes the 2017 campaign with a 4.88 ERA over seven appearances (six starts) and an unattractive 15:19 K:BB ratio. He begins the long road to recovery, as Dinelson Lamet takes over his spot in the starting rotation.

Cosart (elbow) received a PRP injection Wednesday and will head to extended spring training to begin his rehab process, AJ Cassavell of MLB.com reports.

EDGE Analysis

The right-hander's first potential return date used to be this Friday, but that clearly is not going to be met due to this development. Cosart was officially diagnosed with a flexor strain, so he will not begin throwing immediately upon his arrival in Arizona. This pushes his timeline well into the future, although no firm return date has been provided at this time. Look for Miguel Diaz and Dinelson Lamet to remain in the rotation while Cosart misses time.

Cosart was placed on the 10-day disabled list Tuesday with a strained right elbow.

EDGE Analysis

It's unclear when this injury cropped up, but it may go to explain why he struggled so much in his most recent start Sunday. The severity is also unknown at this point, although since the DL stint was backdated to Monday, he'll first be eligible to return June 16 when the Padres take on the Brewers. To fill his spot on the roster, Jose Pirela was brought up from Triple-A, although a starter will likely need to be brought up from the minors to make his next scheduled start this weekend in Kansas City.

Cosart (0-2) allowed nine baserunners and three runs over four innings Sunday. He struck out five in a 3-1 loss to the Rockies.

EDGE Analysis

The 27-year-old limited the hard contact against a powerful Rockies lineup, but a parade of singles and walks ended his day before the fifth inning for the third consecutive start. Cosart's terrible control (0.8 K/BB) and inability to go deep into games has made him tough to tolerate even as a deep-league option. That said, the righty draws a favorable matchup at home against the Royals next Saturday, but it would be tough to recommend him as a safe option.

Cosart allowed two runs on three hits while walking five and striking out two over four innings for a no-decision in Monday's 5-2 win over the Cubs.

EDGE Analysis

Cosart was making his first start since taking a liner off his foot May 18, so the Padres weren't pushing him in the 87-pitch outing. Regardless, the 27-year-old right-hander has pitched into the fifth inning just once in his five starts and sports a weak 4.5 K/9, ugly 7.2 BB/9 and shaky 4.50 ERA in 20 innings. Cosart would likely be in the bullpen or in the minors if he was on most other teams than the Padres.

Cosart (foot) was confirmed as the starting pitcher for Monday's game against the Cubs, Bob Scanlan of Fox Sports San Diego reports.

EDGE Analysis

As expected, Cosart will make his scheduled start against the Cubs after taking a liner off his foot during his last start. He'll look to bounce back from his last outing that saw him allow four runs in just 2.2 innings before being pulled. The 26-year-old has compiled a 3.52 ERA in the four games (15.1 innings) he started.

Cosart is day-to-day after X-rays on his foot came back negative Wednesday, Dennis Lin of The San Diego Union-Tribune reports.

EDGE Analysis

Cosart took a liner off his right foot in the second inning Wednesday, and while he was in noticeable pain, the 26-year-old was able to stay in the game. He allowed four runs on four hits and four walks before being pulled just 2.2 innings into the game. It's unclear if Cosart will be able to make his next scheduled start Monday against the Cubs, but that should become clearer in the coming days based on how his foot feels.

Cosart allowed one run on five hits and a walk over five innings Thursday against Milwaukee. He struck out three.

EDGE Analysis

It was a good outing for Cosart, who was just reactivated from the disabled list on Sunday to make his third start of the season. Although he only lasted 72 pitches, the 26-year-old worked effectively with a sharp curveball throughout the contest, and cooled down a hot Milwaukee offense. Cosart showcased a shortened delivery that seemed to have the Brewers' bats off-balance from the outset. His next turn is scheduled for Wednesday -- the same day Trevor Cahill (shoulder) is eligible for a return from the DL -- so it remains to be seen whether Cosart will get another start or be optioned into a long relief role.
