SCOTTSDALE, Ariz. — The Rockies breathed a sigh of relief Saturday morning.

Right-handed starter Tyler Chatwood called his hamstring injury “minor” and said he intends to make his first regular-season start Wednesday in Miami against the Marlins.

“I don’t think it’s very bad,” Chatwood said. “They told me it was just a minor strain and a little cramping, and they took me out to try and protect it. I am going to do everything I normally do the day after I pitch. Right now I’m still on track for that first start.”

Chatwood left Friday night’s Cactus League game against the Mariners in the third inning after sprinting out a leadoff triple.

If Chatwood misses any starts, right-hander Jordan Lyles, optioned to Triple-A Colorado Springs on Friday, would be called back up.

No. 1 right-hander Jhoulys Chacin is already on the disabled list until May, so it would have been a big blow to lose Chatwood for any length of time.

When Chatwood pulled up lame at third base Friday night, it looked like it could be a major injury, but trainer Keith Dugger told pitching coach Jim Wright that Chatwood should be fine.

“According to Doogie, all systems are go right now,” Wright said.

As Wright watched Chatwood run the bases Friday, the thought that popped into Wright’s mind was “a double would have been fine. During the season, go for the triple.”

Chatwood, a good hitter and good athlete, said he didn’t receive criticism for legging out an extra base in an exhibition game.

“The ball hit in the gap and when I rounded second (base) I hit a little soft patch of dirt,” he said. “But it’s going to be OK.”

Manager Walt Weiss joked a little about the injury Friday night.

“I told him to take one pitch and then hit a double,” Weiss said. “so then I went out there and told him, ‘I told you to hit a double, not a triple.’ He said, ‘I know, I messed it up.’ “

Weiss said he wasn’t kidding, then added: “He’s a great athlete and he runs really well and it was going to be an easy triple. You never know when these things are going to pop up.”
