The Colorado Rockies got a scare on Tuesday when prospect Jon Gray left with abdominal tightness after facing only three batters in a spring training game against the Milwaukee Brewers.

Gray, who was drafted third overall in 2013, was expected to be in Colorado's starting rotation.

The 24-year-old is expected to undergo an MRI.

"He said he was feeling it on certain pitches," Walt Weiss said. "When you hear that you just take him out."

Rob Manfred won't decide on how to discipline Jose Reyes until the Colorado Rockies shortstop's domestic violence case plays out in court.

"It depends on the circumstances of each case," Manfred said. "I can imagine a scenario where you're able to get all the information and put yourself in a position to make a decision.

"On the other hand, I think the single biggest mistake you can make here is to make a decision quickly and then have additional facts come out afterward and undermine the quality of that decision."

Reyes is scheduled for an April 4 trial on a charge that he abused his wife Oct. 31 at a Hawaii resort. Reyes has pleaded not guilty.

Before spring training, Manfred placed Reyes on paid suspension under the domestic violence agreement reached in August.

"Once that process plays out, I think we'll be in a position to have access to all the facts and be in a position to act quickly," Manfred said.

Troy Tulowitzki told USA Today recently that he prefers his new spring training home with the Toronto Blue Jays in Dunedin, Florida, to the 140-acre complex that the Colorado Rockies and the Arizona Diamondbacks share at Salt River Fields at Talking Stick.

"I like this place a lot better than Arizona," Tulowitzki said. "That place was like a country club. Guys got comfortable because it was so nice."

Walt Weiss took issue with the comments on Monday.

In his fourth year as manager of the Rockies, he disputed the notion that the Colorado players have gotten soft because of the amenities at Salt River Fields. Colorado's half of the facility includes six practice fields, modern training and video rooms, a 108-seat theater and an 11,000-square-foot weight room.

"I think that's the furthest thing from the truth," Weiss said. "We have a nice place here and we're proud of it, but our guys are mentally tough and they compete. I have no issue with our guys being soft or country-clubbish. Our guys are the opposite of that.

"It's a great facility. It's beautiful. We talk about gaining a competitive edge because of this facility. A facility doesn't change their mentality. We've got guys who work hard, play hard and compete extremely well."
