Mets' Steven Matz to miss start with issue in shoulder

SAN FRANICSCO -- The injury jolts keep coming for the New York Mets.

Manager Terry Collins announced that left-hander Steven Matz would have Friday's start skipped against the San Francisco Giants because of shoulder discomfort.

Rookie Seth Lugo instead will start.

The hope is that Matz only misses one rotation turn.

He is coming off an outing in which he allowed only one hit in 7 1/3 scoreless innings against the San Diego Padres on Sunday.

"I was throwing on flat ground and I felt a little twinge in my shoulder," Matz said. "It was bothering me a little bit. And then next day I was throwing and I was still feeling it, so I didn't throw my bullpen, hoping it would get better. I was just kind of taking it day by day. There's some discomfort in there. I think you go through stuff all the time throughout a season, but it didn't respond the way I'd like it to."

Matz said he is not concerned about the issue lingering.

"Not so much," Matz said. "It's just discomfort. I'm really not worried about it."

Matz has been pitching with a bone spur in his pitching elbow that will need to be surgically removed after the season. Manager Terry Collins said he is confident

Matz did not alter his mechanics to compensate for an elbow issue and harm the shoulder. The Mets, like all major league teams, now have access to sophisticated real-time data about their pitchers' mechanics.

"I've been feeling great. I really have been," Matz said about the elbow. "It's disappointing that I really didn't bounce back like I wanted to this past start. But I'm really not too, too worried about it. Hopefully it's just this one [missed start] and just keep going forward."
