PHOENIX -- The Rockies had rehabbing closer Huston Street start Friday night's game for Triple-A Colorado Springs on a 25-pitch limit. He didn't need nearly that many.

Street used 12 pitches to retire Reno during a perfect first inning, with one strikeout.

It was the first game of a new rehab assignment for Street, who was placed on the disabled list to start the season because of right shoulder inflammation and then suffered a groin strain in his second rehab game for Double-A Tulsa.

In another development, the Rockies placed pitcher Greg Smith on the Colorado Springs disabled list with a left shoulder injury. He was removed from Thursday night's game after throwing 28 pitches. Rockies manager Jim Tracy said he is not sure the specifics of the injury.

De La Rosa expects to return in near future

PHOENIX -- Rockies pitcher Jorge De La Rosa is finally comfortable with a timetable for his return to the mound. It coincides with an even more special timeline.

On Saturday, De La Rosa will throw his first bullpen session since suffering a torn band on a ligament in his left middle finger on April 25. He said he could make his return in about a month.

Earlier this week, De La Rosa went home to Hermosillo, Mexico, to work on obtaining visas so that his infant twin sons, Matias and Bernabe, can come to America.

"It could take three weeks, maybe a month," De La Rosa said. "It could be at the same time [that he returns to the Rockies]."

The Rockies originally said De La Rosa would throw off a mound on Friday, but he played long toss at 200 feet instead and planned a full bullpen session for Saturday.

Since starting the 2009 season 0-6, De La Rosa has gone 19-4.

Tracy thinks Tulo is an All-Star

PHOENIX -- Rockies manager Jim Tracy took time Friday to stump for shortstop Troy Tulowitzki in his candidacy for the starting lineup in the July 13 All-Star Game in Anaheim.

According to the latest ballot update, Tulowitzki was third behind the Phillies' Jimmy Rollins and the Marlins' Hanley Ramirez in voting. Tulowitzki was the only Rockies player in the top five at positions other than the outfield, and no Rockies player was in the top 15 among outfielders.

Rollins is out with a calf injury, so being healthy helps Tulowitzki, who is the best chance for the Rockies to have a player voted a starter by fans since 2003, when Todd Helton was chosen for the second consecutive year. The last Rockies player to start the game was outfielder Matt Holliday, now with the Cardinals, who was named by then-Rockies manager Clint Hurdle to start in 2008.

"I really believe this: with Jimmy Rollins [not] healthy, I believe 'Tulo' should start getting some of the national attention that he justifiably deserves," Tracy said. "This is a very, very special baseball player. There are quite a few credentials that one needs to posses to become one of the big-time foundational players of the club, and it's safe to say that he is that."

Tracy, noting how the Rockies surged to the playoffs in 2009 and have shown signs of being a factor in the National League West this year, said he hopes the attention coming to Tulowitzki and star right-handed pitcher Ubaldo Jimenez will help illuminate some of the other positive developments on the club.

"When you play the kind of baseball that we've played since late last May a year ago," Tracy said. "If I'm over on the East Coast, I'm getting to the point where I'm asking questions, 'Hey, what is it about the Rockies?'"
