DENVER -- Rockies reliever Rafael Betancourt remained unavailable for Wednesday's series finale against the Braves. But with the day off on Thursday, the Rockies are hoping to have him for the weekend series against the Dodgers.

Betancourt, nursing an abdominal strain, did not pitch on Tuesday.

"It's still sore," he said. "We're going to do the same thing today -- rest, treatment, ice."

The right-hander blew his fourth save of the year on Monday, when he yielded a run against Atlanta, but he also ended up with his fourth win after the Rockies rallied. His strikeout-walk ratio of 9.57-1 (67 strikeouts, seven walks) is the second-best ratio among big league relievers.

"We really want to be proactive with this one," Rockies manager Jim Tracy said. "By staying away today and having the day off tomorrow, we'll have a much better idea on Friday. Hopefully, he's going to come in and be fine."

In other Rockies pitchers injury news, starter Jeff Francis threw long toss on Wednesday morning while reliever Matt Daley threw a bullpen session on Tuesday. Aaron Cook remains scheduled to start for Double-A Tulsa on Saturday and Taylor Buchholz was in Denver for treatment Wednesday.

Iannetta earns starting nod behind plate

DENVER -- Weeks back, Rockies manager Jim Tracy was looking for ways to further incorporate Chris Iannetta into the regular lineup.

With Iannetta's increased success behind and at the plate and the recent slump of fellow catcher Miguel Olivo, Tracy has found a way.

"I don't give out handouts," Tracy said. "You earn it. And he's earned it."

Iannetta, behind the dish for Wednesday's finale against Atlanta, will have started 11 games since Aug. 4.

"Every time I see more, I get more and more excited as to the steps he's taken defensively in upgrading his game," Tracy said. "And I mean that both on the physical and mental side. An incredible amount of improvement." Entering Wednesday, Ianetta had a .343 on-base percentage and .411 slugging percentage since returning from Triple-A Colorado Springs on May 27. Meanwhile, Olivo -- an All-Star Game candidate earlier in the year -- has hit .146 since the break.

"In no way am I taking from one to give to another," Tracy said. "I have the opportunity to utilize both because of the circumstances in front of me. If that is, in fact, the case, I'm going to jump all over that."

Young, Fowler living the dream in Colorado

DENVER -- As roommates coming up through the Rockies' farm system, Eric Young and Dexter Fowler used to stay up late talking about one day playing for the big league club together.

Now, the duo is making the dream a reality.

Since Young was recalled from Triple-A Colorado Springs on Aug. 14, the two have started every game for the Rockies. Their speed and athleticism provide a formidable challenge for opponents at the top of the Colorado order.

"Whenever we can get that kind of production at the top, I think it's going to create opportunities for guys No. 3 and lower to drive in some runs," Young said.

Entering Wednesday, Fowler had 12 hits and four runs in his past nine games, including a key two-out single on Tuesday night. Young, who was 3-for-4 with a stolen base on Tuesday, sparked the Colorado offense with a leadoff double in the 5-2 win.

"I know my job's to get on base and that's all I'm thinking about," Young said. "Whatever I can do to get on base, that's all I'm trying to do."

Worth noting

Rockies manager Jim Tracy said he likes outfielder Carlos Gonzalez in left field at Coors Field more than right field not due to his recent knee injury, but because of the ground Gonzalez can cover. "He's in left now in this ballpark because of the additional ground," Tracy said. "We're trying to defend the field. You saw him in right field on the road because of the symmetry of the ballpark we were playing in. But because there's a little more real estate from that left-field line to that notch out there, there's more ground to cover." Gonzalez has started 21 games in right and 36 games in left field, including Wednesday's. He's also played 51 in center.
