Recently acquired reliever Boggs sent to Triple-A

DENVER -- The Rockies sent right-handed reliever Mitchell Boggs to Triple-A Colorado Springs on Saturday to make room for Saturday's starter against the Brewers, Collin McHugh.

Boggs, 29, appeared in just two games with the Rockies after they picked him up in a trade with the Cardinals on July 9 in exchange for an international-signing-bonus slot. He was called up on July 20 after closer Rafael Betancourt went to the disabled list with appendicitis.

Manager Walt Weiss said he chose to send Boggs down rather than infielder Jordan Pacheco or recently recalled outfielder Corey Dickerson due to concerns with outfield depth, since Carlos Gonzalez continues to nurse a right middle finger sprain.

The move leaves the Rockies with seven bullpen arms, but Weiss said the outfield was more of a pressing concern.

"We've been going with the extra pitcher," Weiss said. "But with our outfield situation, we felt like we needed a little more protection there as opposed to pitching right now."

Boggs was a lights-out reliever for the Cardinals last season, boasting a 2.21 ERA in 78 appearances (73 1/3 innings). But he struggled to find success this season, and he was demoted to Triple-A Memphis at the end of May before the Rockies traded for him.

He did not allow a run and gave up one hit over 1 2/3 innings with the Rockies, and Weiss expects Boggs to rejoin the bullpen before season's end.

"More than anything, it was the timing of it," Weiss said. "We like what we see, and we think he's going to be in the mix again for us. We just didn't get to see him a whole lot. It helps that I think he'll go down there, and he'll get some consistent work.

"But it's an arm that we really like. It's a power sinker and a hard slider, and he's got a nice track record up here. He's a guy that's going to be in the mix for us."

Betancourt recovering; no timetable for return

DENVER -- Rockies closer Rafael Betancourt is on the road to recovery from an emergency appendectomy eight days ago.

Betancourt was placed on the 15-day disabled list on July 19, but Rockies manager Walt Weiss isn't sure when he'll be ready to pitch.

"We're just waiting for Rafy to heal up," Weiss said. "He's been sore, and he's trying to get back to full strength.

"But it's going to be a little while -- don't know exactly how long. But he's just trying to get healthy again, get his strength back."

Left-handed reliever Rex Brothers took over closer duties in Betancourt's absence, though he's had few chances to pitch due to the Rockies' recent woes. Brothers has converted both of his save opportunities since Betancourt went down, despite allowing a run in a 4-3 victory over the Cubs on Sunday.

CarGo sits for second straight game with finger injury

DENVER -- Carlos Gonzalez missed his second straight game Saturday as he continued to deal with the pain of a right middle finger sprain that he aggravated in his first at-bat on Thursday night.

Gonzalez said Friday that he expected to play through the pain and discomfort associated with the sprain for the remainder of the season. He was also confident that it was not serious enough to force him to the disabled list.

Rockies manager Walt Weiss once again said he will exercise caution with Gonzalez's injury.

"It's getting a little better," Weiss said. "I just wanted to make sure that when I throw him out there, he's ready to go, and we could ride him for a while -- want to make sure he's healthy enough that we can do that.

Gonzalez's 26 homers are tied for first in the National League, and he also leads in slugging percentage (.597) and total bases (225). Though the Rockies' offense showed it could produce without its usual No. 3 hitter in an 8-3 win over the Brewers on Friday night, Gonzalez leads the team in RBIs (67), hits (112) and runs (71).

Weiss said he doesn't believe Gonzalez ever fully recovered from the initial injury, suffered on July 7 against the D-backs, which caused him to miss two games.

"I think it's been a factor for a while, ever since he hurt it," Weiss said. "I don't know if it's ever going to completely go away the rest of the season, but hopefully, it will get to the point where it feels good enough to go out there, and he can do his thing. Because even when he's not 100 percent, he's talented enough that he can carry our club.

Worth noting

• Pitcher Roy Oswalt said he felt good after throwing 15 pitches off the mound on Friday at about 80 percent power, and he will toss a bullpen on Tuesday at Turner Field, where the Rockies will be for a four-game series against the Braves.

Oswalt, who has an 0-4 record and a 7.64 ERA in four starts for the Rockies, was forced to the 15-day DL on July 8 with a left hamstring strain.
