COL@SF: De La Rosa works out of a bases-loaded jam

SAN FRANCISCO -- Rockies left-handed pitcher Jorge De La Rosa left Friday night's game against the Giants after three innings because of lower-back tightness. The Rockies announced his status as day to day.

On Friday, De La Rosa threw two scoreless frames but began laboring during the third. Angel Pagan doubled and Hunter Pence singled him home to lead off the bottom of the third. After retiring the next two batters, De La Rosa looked to the dugout while facing Michael Morse. Assistant trainer Scott Gehret, pitching coach Jim Wright and manager Walt Weiss visited the mound.

After declaring himself OK after a few warmup pitches, De La Rosa finished the inning, giving up a second run on a Morse single to tie the game at 2. Tommy Kahnle replaced De La Rosa in the bottom of the fourth.

It's the second bout with back problems for De La Rosa (6-5, 4.12 ERA) this season. On May 7, he went six innings and gave up two runs while earning a win over the Rangers in Arlington. But while doing his between-starts running, his back tightened and his next start was moved to May 16. The start against the Rangers was also where he sustained a middle finger bruise that has affected him consistently since.

The Rockies have three starters on the disabled list. Lefty Brett Anderson hasn't pitched since April 12 because of a broken left index finger and righty Tyler Chatwood last pitched on April 28 because of a right forearm strain. Both are on the 60-day DL and on Friday both threw their first full bullpen sessions since their injuries.

Right-handed prospect Eddie Butler made his Major League debut last Friday in a loss to the Dodgers, but within days was placed on the 15-day DL. Butler hopes to be cleared to resume long-toss on Saturday.

Rockies seek turnaround on West Coast swing

ATL@COL: Tulo spins and fires to complete great play

SAN FRANCISCO -- Rockies shortstop Troy Tulowitzki understands as well as anyone that there are many ways to read the standings a month before the All-Star break. They were four games under .500 with losses in 15 of 20 going into Friday night, but also just 3 1/2 games out of the National League Wild Card going into the game against the Giants.

But the Rockies have a chance to bring clarity to their season by the break. Perform well, with this three-game weekend series against the NL West-leading Giants and the two series totaling seven games with the second-place Dodgers, and the Rockies can call themselves contenders.

"The pitching the last two games really helped; if they can give us some good starts, we'll be fine," Tulowitzki said. "The key, obviously, is holding our own on the road. If we can do that and get back to the home dominance, we'll be fine."

But if the Rockies continue to struggle, questions about Tulowitzki's future will come, despite his contract running through 2020.

"No doubt," Tulowitzki said. "Anytime you're on a team you want to focus on, 'Come to the park every day and win games,' it makes your job easier. I've dealt with both sides.

"Obviously, when we're in it and talking about playoffs, it's a lot easier than when you're talking about, 'Are they going to trade certain guys?' Those thoughts make it more difficult to come to the park."

There is no indication that Rockies ownership and management is considering becoming a seller before the July 31 non-waiver Trade Deadline. But to not have to deal with the question, the Rockies need a turnaround, with the likelihood that left fielder Carlos Gonzalez, right fielder Michael Cuddyer and pitchers Brett Anderson and Tyler Chatwood won't return from their long-absence injuries before the break. Third baseman Nolan Arenado and pitching prospect Eddie Butler should return before the break, but some of these key games will be played without them.

Can they save their season with so many players missing?

There may be a better question: Do they even need to be thinking about the big picture?

"I don't think we have to prove to anything but ourselves," said center fielder Drew Stubbs, who has spent his career with contending teams, having played for the Reds and Indians. "Going into this stretch, and when you start heading toward the Trade Deadline, a lot of teams are trying to decide, 'Are we a contender or are we going to build for next year?' This time between now and then is going to determine a lot for us.

"But I think it's imperative for us as players not to worry about any of that stuff. We just need to be productive on the field and try to win games. The other peripheral stuff will be decided by the staff and the front office."

It's not as if the schedule will give the Rockies many breaks. Including Friday, the schedule calls for 29 games in the next 31 days.

"I don't want to say we need to tread water because we still have enough talent here to win baseball games," veteran first baseman Justin Morneau said. "If we do well between now and the All-Star break, we'll start getting guys back and it'll be like making moves at the deadline."

For those returns to matter, the Rockies need frontline production from players forced into action now -- such as pitching callups Christian Bergman and Tyler Matzek, who had impressive debuts; infielders Josh Rutledge, Charlie Culberson and Ryan Wheeler; and outfielder Corey Dickerson.

"Everybody in this locker room deserves to be here and we've got a good group of veterans," Dickerson said. "We're behind two teams, but we play those guys many times and other teams can go into droughts, also. We've got to keep battling."

If the Rockies succeed at the battle, they can finish with the same team they brought into the season, or an improved one rather than one broken down to build for the future.

"You have to ask some of the other guys, but hopefully they are aware -- because if you are, you understand how important each and every day is," Tulowitzki said.

Rockies receive positive reports on injured players

ATL@COL: The Rockies booth announces CarGo's surgery

SAN FRANCISCO -- The tumor removed from the left index finger of Rockies left fielder Carlos Gonzalez on Tuesday was diagnosed as a post-traumatic neuroma, or nerve-related tumor, which is benign. The end of the Rockies' tweet says all laymen need to know: "Aka: good news."

The pathology report on Gonzalez, whose return won't truly be known until after his stitches are removed in a little less than two weeks, was part of a positive day of health news for the Rockies.

Right-handed pitcher Tyler Chatwood (right flexor tendon strain) and lefty Brett Anderson (broken left index finger) each threw a bullpen session Friday, their first since they were placed on the disabled list. In each case, it was 25 pitches, all fastballs, and it went well.

Also, righty Eddie Butler, who made his Major League debut in a loss to the Dodgers last Friday and went on the 15-day disabled list with right shoulder inflammation immediately thereafter, has responded well to strengthening exercises. Butler said he hopes to throw long-toss at 90 feet on Saturday, if cleared to do so.

Third baseman Nolan Arenado, out since May 23 with a broken left middle finger, had an intense running workout Friday. The Rockies will re-evaluate the finger when they return from the current road trip Thursday. If all goes well, he's a candidate for a Minor League rehab assignment.

Rockies reach agreement with third-round Draft pick

2014 Draft: Rockies draft LHP Sam Howard No. 82

SAN FRANCISCO -- The Rockies and Georgia Southern left-handed pitcher Sam Howard, their third-round pick in this year's MLB First-Year Player Draft, reached an agreement on a bonus worth $672,100, MLB.com has learned.

The amount is full slot value for the 82nd overall pick that the club used for Howard.

The Rockies have not confirmed the Howard deal.

The final numbers on the bonus agreement from the Rockies' second-round pick are in, according to SB Nation and confirmed by MLB.com. Phoenix (Arizona) Brophy College Preparatory School right-hander Ryan Castellani signed for $1.1 million, $58,000 below the slot for the 48th overall pick.
