CHICAGO What should have been a feel-good performance and nice segue into the Subway Series for the Mets turned into something of a demoralizing win Sunday night. after umpires inspected his right hand and deemed him in violation of MLBs rules on sticky substances. Drew Smith and Jake Diekman were summoned to get the final three outs of the Mets 5-2 victory over the Cubs, but Diaz now faces a 10-game suspension during which the team cant replace him on the roster for the sticky substance ejection.

USA TODAY Sports via Reuters Con Well pay the price, but well use this as a teaching moment, manager Carlos Mendoza said. But guys will find a way to get through it. Diaz said he used the same combination of sweat, rosin and dirt that he usually employs on the mound to get a better grip on the ball. He said he was informed by umpiring crew chief Vic Carapazza that the amount of substance on his right hand was in exce s, and by rule he was ejected. Explore More I understood, but at the end of the day I was using sweat, rosin and I put my hand on the dirt, Diaz said. Its tough, because I will let my teammates down for 10 games. That sucks, because coming back from the [injured list], I have been good to help this team to win and now being out 10 more days really sucks. The Mets had two pitchers Max Scherzer and Smith suspended last year for violating the sticky substance rule. Diaz can appeal his suspension, but will face a losing battle given that the judge and jury will be MLB officials using the report from Carapazza and his crew as the overriding evidence.

USA TODAY Sports via Reuters Con We have been through a lot this year and we will find a way to get through it, Mendoza said. Diaz said he believes the umpires were under the a sumption he was using an illegal substance. The right-hander Bojan Bogdanovic Jersey offered to let them smell his hand and conduct other testing, but said by that point a decision had already been reached. But Mendoza said Carapazza told him the i sue was the combination of rosin, sweat and dirt that was a little too much. Mendoza said he never checks hands so was in no position to say one way or another if Diaz was in exce s with his application of the mixture. Smith was thrust into the game on short notice and after getting two outs and allowing a hit was replaced out of fears he would injure himself. Diekman recorded the final out. Edwin Diaz was ejected from the Mets-Cubs game on Sunday. Screengrab I was a little stiff and had trouble warming up a little bit, Smith said. I have been throwing a lot this week I probably could have taken more time out there to warm up to be completely honest. In a test of guts, Luis Severino prevailed and helped the Mets win the series. Severinos six shutout innings were a marked improvement from his Tuesday outing in Texas in which he surrendered six earned runs.
