Cosart (elbow) was transferred to the 60-day disabled list Thursday. 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. 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. The right-hander's first potential return date was this Friday, but that clearly is not going to happen based on the news. 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. 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, but 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 six hits, three walks and three runs over four innings Sunday, striking out five in a 3-1 loss to the Rockies. 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. 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.
