Yankees closer Aroldis Chapman felt pain and discomfort in his shoulder for weeks before alerting the team, he told reporters on Sunday.
Chapman was placed on the 10-day disabled list on Sunday due to left rotator cuff inflammation and could miss roughly a month.
"I heard Chapman tell you guys that, and all I can tell you is that he didn't mention anything," GMBrian Cashman said Monday, according to Dan Martin of the NY Post. "We check every day with the trainers to see what they're doing or if anyone is deviating from their routine. That's all you can do."
"If they conceal it, then it becomes veterinary care," Cashman added. "If the patient can't tell you what's wrong, you have to go off symptoms or poor performances and it's nothing but guesswork. We ask all the questions. Maybe it's easier for them to convey to [the media] after the fact."
Chapman has struggled as of late, giving up four runs and six hits in his last two outings. He blew his first save of the 2017 season against the Cubs on May 7 and surrendered three hits and one run in a 5-1 loss to the Astros at Yankee Stadium on Friday.
The closer owns a 3.55 ERA, seven saves, 21 strikeouts and a 1.42 WHIP. Before his appearance against the Cubs, the last time Chapman gave up an earned run was on April 26 versus the Red Sox.
The Yankees recalled right-handed pitcher Chad Green from Triple-A and INF/OF Rob Refsnyder will also be called up prior to the second game of Sunday's doubleheader.
May 14: Chapman had not looked himself since the Boston series. While he was still generating fastball velocity in the 101 miles per hour area, his command was off and simply didn't look comfortable on the mound. Hopefully the rest will get him back to being the dominant reliever he has shown to be.
This is the first test of the Yankees' pitching depth this season. Until now, the pitching staff had been healthy and it experienced success. With Dellin Betances moving into the closer's role, each of the other relievers will also have to step up in an enhanced pressure spot.
This will also be another test for Betances, who struggled at the end of last season in the closer's role. Betances has the tools to succeed as a closer, but when he has been afforded the opportunity in the past he has been inconsistent. At times he has carried over stellar work from his eighth inning role, but unfortunately it has been balanced by severe swings of inadequate performance. It was likely one of the reasons the Yankees paid top dollar for Chapman this offseason.
For the Yankees to stick at the top of the division standings, Betances and the rest of the relievers will have to buckle down and fill the void left by the flame-throwing Chapman.
