Worth noting

• Right-hander Juan Nicasio, who suffered a fractured skull and broken neck when hit in the right temple with a line drive in 2011, said Monday he is open to wearing a padded cap, which is available this season. Major League Baseball has approved a cap produced by isoBlox, and other companies are working on technology to give pitchers protection.

Nicasio said he wants to test out some padded caps in Spring Training games.

"I just want to be comfortable," he said.

• Catcher Jordan Pacheco wore No. 58 when he first appeared in the Majors in 2011 before switching to No. 22 in 2012 and No. 15 last season. But when Rockies catching coach Jerry Weinstein took a job in the team's Minor League system, No. 58 opened again and he grabbed it.

Pitcher Tyler Chatwood gave up No. 32 for new closer LaTroy Hawkins, who is 41 and has seniority, and wore the number for the Rockies in the 2007 World Series. Chatwood will wear No. 27.

• Chatwood quietly underwent surgery to remove bone chips at the end of last season. He said Monday that there are no lingering issues.

"I'm full-go, 100 percent, no problems at all," Chatwood said. "We knew I was going to take a break, see how it felt and go from there. A couple weeks into it, me and [Rockies head athletic trainer Keith Dugger] talked and it was kind of the same feeling, so we went in there and it was a good thing. I had a bone chip, a pretty good-size one. It was causing all the inflammation and fluid."

Chatwood went 8-5 with a 3.15 ERA in 20 starts last season.
