DENVER -- Rockies starter Aaron Cook scattered five hits and two runs over 5 2/3 innings, earning the win in his second rehab outing for Double-A Tulsa in an 8-4 victory against Northwest Arkansas on Saturday night.
The right-hander struck out six and walked two.
Rockies manager Jim Tracy said before Saturday's game against the Dodgers that, if all goes as planned, Cook is expected to start Thursday's makeup game against the Phillies in Denver.
"We're a couple days away from the month of September and 4 1/2 games from a playoff spot, so what you see between the lines goes a long way in dictating playing time or how you're going to set this or that up," Tracy said. "We want to see how he does."
In his first start with Tulsa, Cook allowed three hits and one run in a five-inning outing.
Cook, on the 15-day disabled list with a sprained right big toe, is 4-8 with a 5.34 ERA this season with the Rockies.
Reynolds solidifying place in Rockies' 'pen
DENVER -- In his first stint in the big leagues, Matt Reynolds is finding himself in a multitude of unfamiliar situations. So far, they've suited him just fine.
Reynolds may have solidified his place in the Rockies' bullpen for quite some time with a stellar performance in Wednesday's incredible comeback victory against the Braves.
In just his fourth career big league outing, the southpaw pitched three shutout innings, allowing one hit while walking three while logging 56 pitches.
"Awesome," fellow reliever Joe Beimel said of the rookie's performance. "I don't know if he's thrown a whole lot of innings down there in Triple-A, but he really stepped up and just came in and threw strikes. That's all we needed."
In fact, Reynolds said it was the longest outing he's thrown all season.
"The last time I threw three innings was last year in high Class A," Reynolds said. "I think I went 2 1/3 or 2 2/3 one other time this year, but the role they've got me in here is I can be doing anything."
In 4 2/3 innings with the Rockies, Reynolds has racked up four strikeouts while allowing just one walk and two hits. He was 1-3 with a 2.62 ERA in 50 relief appearances for Triple-A Colorado Springs this season, earning a spot on the Pacific Coast League All-Star team.
Despite his experiences with the Sky Sox, he was able to accomplish another feat on Wednesday, drawing a fifth-inning walk and coming around to score in what Braves manager Bobby Cox called the turning point of the comeback effort.
"I don't know if I so much worked the walk," Reynolds said with a laugh. "But I haven't had an at-bat since junior college, so like six years ago. I'd been on deck a few times. I don't know if I've ever felt more awkward on a baseball field."
Francis, Daley close to simulated game action
DENVER -- Rockies manager Jim Tracy said injured pitchers Matt Daley and Jeff Francis threw successful side sessions on Friday, will throw again on Sunday and could be in line to throw simulated starts on Tuesday in San Francisco.
With Triple-A Colorado Springs' schedule wrapping up Sept. 6, Tracy said he's hopeful the two pitchers would have the opportunity for rehab starts before rejoining the Rockies.
"If we pass the tests tomorrow, we'll move toward Tuesday and tackle that one," Tracy said. "And if we pass that one, we'll move out beyond there to see what we have as far as rehab."
Daley has not pitched for Colorado since June 10 and was transferred from the 15-day disabled list to the 60-day DL with right shoulder inflammation on Aug. 3. Francis, suffering from left bicep soreness, was placed on the 15-day DL on Aug. 14.
Rockies starter Aaron Cook is also scheduled to start for Double-A Tulsa on Saturday. If all goes well for Cook, who scattered three hits and one run over five innings in his first rehab assignment, he would start in Thursday's makeup game against the Phillies.
"He's going to spot start on Thursday and, obviously, we've got a few more games to play between now and his spot start on Thursday," Tracy said. "And the combination of all of it, how we evaluate it, will go a long way in determining how we go from a rotational standpoint as we move into September."
Stewart develops soreness in batting cage
DENVER -- The Rockies held Ian Stewart out of the lineup for the second straight game after the third baseman apparently injured himself while taking some practice swings in the batting cage during Friday night's game against the Dodgers.
"In the middle of the game, he went to the cage to take some swings and took a swing and felt some soreness in his side," Rockies manager Jim Tracy said. "He was treated last night as the game was going on, came back in today and is still sore enough to where he's not able to participate."
Melvin Mora, who started at third base on Friday night -- because of the pitching matchup, not Stewart's injury -- was at third again on Saturday for the Rockies.
Tracy said Stewart was listed as day-to-day.
Stewart has started 100 games for the Rockies this year, all at third base. Saturday will be Mora's 27th start at the position. Stewart is hitting .278 with five doubles, seven homers and 16 RBIs with a .504 slugging percentage since the All-Star break. Mora was 2-for-4 with an RBI on Friday and was hitting .311 at Coors Field this year entering Saturday.
The Rockies' rookie-level team in Casper erupted for 26 runs against Missoula in a 26-3 victory on Friday night. The Ghosts had 27 hits (14 for extra bases), including six homers. All nine starters had at least two hits and three players (center fielder Rafael Ortega, left fielder Corey Dickinson and first baseman Blake McDade) had four hits each. The lopsided win came a night after Casper fell to Helena, 20-8.
