DENVER -- The Rockies announced on Saturday that they have agreed to terms with 11 of their picks from the 2010 First-Year Player Draft.

The group of players includes three prospects selected in the first 10 rounds, most notably Chad Bettis (2nd round), a closer out of Texas Tech.

Bettis, who worked as a closer for Team USA and has a fastball that tops off at 98 mph, led the Red Raiders in saves (10) and strikeouts (102) in 85 2/3 innings this year. He is expected to make his professional debut for Class A Short-Season Tri-City.

The Rockies also agreed to terms with Jared Simon (6th round, OF, Tampa), Corey Dickerson (8th, OF, Meridian Community College) and Jordan Ballard (33rd, 1B, Virginia Military Institute).

"It shows you their eagerness to get out there and play," said Rockies vice president of scouting Bill Schmidt.

Mark Tracy, Rockies manager Jim Tracy's son and a 22nd round choice out of Duquesne, also agreed to terms.

Tulowitzki tweaks groin, rests on Saturday

DENVER -- Rockies shortstop Troy Tulowitzki suffered a slight groin strain while sliding on the wet turf at Coors Field during Friday night's 5-3 victory over the Blue Jays.

That discomfort, coupled with another wet day at the yard were enough to lead manager Jim Tracy not to start him Saturday night. Tracy said that Sunday is a "wait-and-see-type thing."

Tracy covered Tulowitzki's absence by moving Clint Barmes from second base to shortstop, dropping center fielder Carlos Gonzalez in the batting order from leadoff to Tulowitzki's third spot, and inserting Jonathan Herrera at second base and in the leadoff spot.

Tulowitzki has a history of pulled muscles. Tracy has exercised caution on days of wet grounds with Tulowitzki throughout the season.

"The wisest thing to do is to bear it in mind," Tracy said. "You ask yourself the question, 'One day or two versus a 15-day disabled list situation?' Anytime you deal with a leg, it's rare that 15 days later a guy is ready to play again. That normally turns in to three weeks to a month."

Spilborghs swinging hot bat for Rockies

DENVER -- Rockies left fielder Ryan Spilborghs was swinging the bat so well on Friday night that he could have gladly made an argument for the game to press on.

The game was called because of weather conditions after six innings, and Spilborghs finished the evening 3-for-3 with two doubles and a home run. He's batting 6-for-7 on the current homestand with three doubles and the home run from Friday.

"He took as good a series of at-bats [Friday] as I've seen him take since I was asked to manage this team," Rockies manager Jim Tracy said. "Not even close."

More notable is Spilborghs' recent success against left-handed pitchers. He's batting .263 (10-for-38) this season and has seven hits in his past 11 at-bats (two doubles, one home run, two walks) against southpaws.

"I haven't been that good against lefties up until recently, but part of that was my mechanics and my swing was longer," said Spilborghs, who hit .230 against lefties last season. "So I worked out some of my mechanics that allowed my swing to be shorter. It doesn't really matter whether you're facing lefties or righties -- if you feel like your swing is in the right spot, and you think your comfort level is up there, I'll throw some quality at-bats up there."

Gonzalez breaks skid with big night

DENVER -- Just as Rockies manager Jim Tracy called Friday night's offensive output one of the best he's seen all season, center fielder Carlos Gonzalez's demeanor after the game was noticeably more cheerful.

Gonzalez, who was 3-for-19 in the club's recent series against Houston, went 2-for-4 with a homer on Friday. Gonzalez, the Rockies' leadoff hitter, ranks first on the club with an RBI in every 6.05 at-bats.

"It's a really good feeling because we've been doing something that we should never do. We never give up," Gonzalez said. "We're not proving it and not scoring runs when we're down. [Friday] night, we did and had a really good game, and hopefully, after this, we're going to continue to do it."

The Rockies still have not scored more than five runs in their previous seven games, but both Gonzalez and his skipper agree that the center fielder's production at the top of the order is a major catalyst when it comes to getting the team going.

"Offensively, there was a much greater focus [Friday]," Tracy said. "There's been a lot of things discussed here over the past few days, or so, and I've said this before -- that as far as the way our offense operates when it does operate very efficiently, the whole is much greater than the sum of the parts."
