Tulo making gains playing through pain

DENVER -- Believe it or not, playing through pain in his right hip flexor has been good for Rockies shortstop Troy Tulowitzki.

The injury occurred during the season-opening series at Houston, but it hasn't hampered him. Tulowitzki went 4-for-13 (.308) with a double, two RBIs and two runs scored during the just-completed series with the Giants at Coors Field.

"There's kind of an art to giving everything you've got, but doing it properly, not trying to overdo things," said Tulolwitzki, whose five RBIs lead the club. "Sometimes that makes you better, too. You play within yourself, relax and don't make your body do things it can't do."

Just the same, he'd rather not hurt. Tulowitzki said before Friday night's opener of three games with the D-backs that he's hurting a little less.

"Playing a day game [Thursday], I got all the rest after the game and today, so it's slowly improving," Tulowitzki said.

Rox looking to sharpen defensive skills

DENVER -- Before batting practice on Friday, Rockies third basemen Chris Nelson and Jordan Pacheco, along with utility man Jonathan Herrera, took ground balls off the bat of Rockies special assistant Vinny Castilla and making throws to first base. Nelson has made two throwing errors and Pacheco one in the early days of the season.

It's part of manager Jim Tracy's idea of paying attention to playing better defense without turning it into a bigger deal than it is.

Through the first six games, the Rockies have eight errors. It took 12 games to reach eight errors last season.

Two of the errors were charged to left fielder Carlos Gonzalez, who has one National League Gold Glove Award, and shortstop Troy Tulowitzki, who has taken the last two Gold Gloves at his position. Another was by center fielder Dexter Fowler, a player the Rockies believe is worthy of Gold Glove consideration. Two more came from second baseman Marco Scutaro, a trusted veteran.

"I certainly don't think that tearing the dugout apart or tearing the clubhouse apart is a real good way of going about it," Tracy said. "It's really bringing way too much light to something that there's been plenty of light brought to it already.

"As good a ballclub as we'd like to be, and understanding that this is something that's held us back, let's all be mindful of it. And let's just get out there and clean some of that stuff up.

"When you have situations from people where you would least expect it from, it's tough enough for them once it's just happened. Then to really bring it to light and make it a major issue ... Let's just let go of it and move on. We're six games into a 162-game schedule."

Worth noting

• Rockies outfielder Charlie Blackmon began an injury rehab assignment (right big toe) on Friday night -- going 1-for-4 with three strikeouts, as Triple-A Colorado Springs dropped its home opener to Las Vegas, 14-0. • Left-handed reliever Josh Outman (strained right oblique) threw a 25-pitch bullpens session, and left-hander Jorge De La Rosa (recovering from Tommy John elbow surgery) threw a 55-pitch bullpen session at the Rockies' complex in Scottsdale, Ariz.

• Rockies outfield prospect Tim Wheeler, hitting .200 with two doubles and four RBIs at Triple-A Colorado Springs, sustained a right hamate (bone in the wrist area) injury that will require surgery and cost him about a month.
