DENVER -- Left-hander Brett Anderson is expected to return from his fractured left index finger to start Sunday for the Rockies following Tuesday's decision to option Yohan Flande to Triple-A.
After the Rockies replaced Flande with first baseman/outfielder Kyle Parker on the active roster, manager Walt Weiss confirmed that Anderson will rejoin the team Wednesday.
"Brett is going to be back here tomorrow, then we'll make plans from there," Weiss said. "We'll make sure he checks out all right. So far, so good so we can be seeing him shortly."
Although Weiss didn't come out and say it, 'shortly' likely means Sunday as Anderson is expected to close out the three-game series against the Twins.
Flande was scheduled to pitch next Saturday, but the Rockies are expected to give Anderson an extra day of rest, likely bumping Tyler Matzek to Saturday. Matzek will remain on normal rest after starting Monday since the Rockies have an off-day Thursday.
Anderson last pitched Monday for Triple-A Colorado Springs, limiting Round Rock to one earned run, six hits and one walk over 5 2/3 innings. He likely won't be officially activated until the Rockies require his services.
"He's probably not going to throw 100 pitches in his first time out back with us, but we feel like things went real well down there with Brett," Weiss said.
Anderson finished his two rehab starts with a 0.96 ERA, eight strikeouts and two walks over 9 1/3 innings. Before breaking his finger during an at-bat versus the Giants on April 12, Anderson owned a 3.60 ERA with five strikeouts and five walks over 15 innings pitched.
As for Flande, Weiss admitted the team considered keeping him in the Rockies' bullpen, but ultimately decided to leave him in his starting role as an insurance policy in Triple-A.
"He has been somewhat of a pleasant surprise," Weiss said. "To be honest with you, when we sat there in Spring Training, we probably weren't planning on Flande being in our rotation at this part of the season … We talked about the possibility of him fitting in the bullpen in the future but it's tough to turn away starting pitching."
The Rockies were forced to call upon Flande to make his Major League debut on June 25 after Christian Bergman's left hand fracture marked the sixth starting pitcher to require a disabled list stint this season. Flande pitched slightly better than his 7.36 ERA indicated over three starts, but over 14 2/3 innings with the Rockies, Flande gave up 21 hits and four walks with seven strikeouts.
Flande never made it past 5 1/3 innings in any of his starts, and surrendered five earned runs in the fifth inning of his last start with the Rockies on Sunday.
Rox rookie Butler to begin rehab assignment soon
DENVER -- Rockies right-hander Eddie Butler will likely begin his rehab assignment in four or five days despite a blood blister reappearing in Tuesday's 45-pitch simulated game.
The blood blister first sprung up toward the end of Saturday's 35-pitch live batting practice session against Carlos Gonzalez. Considering Butler feels fully healed from the right rotator cuff inflammation that originally sent him to the disabled list on June 9, he isn't going to let this blister stop him.
"[The blood blister] came back today on the second-to-last pitch," Butler said after facing Charlie Culberson Tuesday. "Just going to get it drained … it's going to be a constant thing."
After throwing without any breaks in between Saturday's session, Butler's outing on Tuesday was split into three increments of 15 pitches. He gave up a double and a walk but said he felt great endurance-wise even after running the bases.
Manager Walt Weiss confirmed that a rehab assignment is Butler's next step, but didn't divulge his exact start date.
"Eddie should be going out soon," Weiss said. "He threw today and looked great. We'll make sure he checks out well tomorrow, then make a decision."
Butler made the leap from Double-A Tulsa for his Major League debut on June 6, but he was shut down three days later after experiencing increased soreness in his pitching shoulder. In that outing against the Dodgers, Butler surrendered six earned runs off 10 hits and three walks. He also struck out two across 5 1/3 innings.
• Parker first made his Major League debut with the Rockies on June 16, finishing 0-for-6 in his five-game stint with the team. In 16 games after being sent back down to Triple-A, Parker hit .277 (18-for-65) with 12 runs, nine RBIs and three home runs.
• Bergman threw a 30-pitch live batting practice session Tuesday as he works his way back from his fractured left hand. After being transferred to the 60-day disabled list on June 25, Bergman isn't eligible to return until Aug. 20.
• Right-hander Jordan Lyles (fractured left hand) is scheduled to throw live batting practice Friday following Monday's 45-pitch bullpen session.
