BALTIMORE -- The Rockies reinstated right-hander Rafael Betancourt as closer on Saturday, and optioned righty Manuel Corpas to Triple-A Colorado Springs to clear a spot on the active roster.
Betancourt (2-3, 3.16 ERA, 15 saves in 16 opportunities in 28 appearances entering Saturday) had been out since undergoing an appendectomy the day the team returned from the All-Star break. Betancourt also missed time earlier this season with a right groin strain.
He pitched a scoreless eighth inning with two strikeouts in Saturday's 8-4 loss to the Orioles, his first outing since July 14.
He made one rehab appearance for Triple-A Colorado Springs before rejoining the Rockies. Manager Walt Weiss talked to Betancourt to determine his mental and physical state before making him closer again. Left-hander Rex Brothers, who has 11 saves in 12 chances, will return to the primary setup role.
Betancourt, 38, said the appendectomy presented a challenge.
"It was kind of weird to be back on the mound," said Betancourt, who has gained back roughly four of the 10 pounds he lost after surgery. "It took some time to feel stronger again, but I'm fine now. I'm just happy to be back, especially after it first happened."
Said Weiss, "If there's a closing situation [on Saturday], we're going to give it to Raffy. It gives us some flexibility with Rex. If it's more of a left-handed inning, we can give it to Rex late as opposed to always having to wait for him to pitch at the end of the game."
The bullpen has worked best this season with Brothers and righty Matt Belisle setting up Betancourt, so Weiss wanted to go back to that plan, even though it's possible Brothers could move into the closer role next season. Both Betancourt and Belisle have mutual options for $4.25 million for 2014, and the Rockies haven't said if they will bring both, or either, back.
The Rockies plan to reduce their number of pitchers from 13 to 12 by the time they arrive in Philadelphia on Monday, after the Interleague series against the Orioles.
Corpas (1-2, 4.50 ERA) was the odd man out because Weiss felt the Rockies needed to carry three left-handers -- Brothers, Jeff Francis and Josh Outman, who has put together several strong outings recently.
"It was a tough choice," Weiss said. "Corpie has thrown the ball well. It comes down to numbers, and we like having a couple lefties in our bullpen going into Philly. It wasn't for lack of performance."
Blackmon, Wieters now have two things in common
BALTIMORE -- Rockies outfielder Charlie Blackmon has been reunited with Orioles catcher Matt Wieters in more ways than one.
In Friday night's 6-3 Rockies victory over the Orioles, Blackmon launched a loud home run that landed beyond Oriole Park at Camden Yards and onto Eutaw Street, something that has been accomplished just 73 times since the park opened in 1992.
Wieters, a teammate of Blackmon at Georgia Tech in 2007, is one of the players to hit one onto Eutaw. Each such homer is commemorated with a baseball-shaped plaque embedded into the walkway.
The two have worked out together some in the offseason but don't spend much time together these days because Wieters is married and has a child. But they talked during batting practice on Saturday.
"He said, 'Nice bomb,'" said Blackmon, who had an RBI groundout and scored a run in Saturday's 8-4 loss.
The homer was long and loud, but Blackmon threw up the stop sign when it was compared to something that happens in a video game.
"In the video game you can hit them off the [warehouse] building, on the other side of the street," he said, laughing.
• Right-handers Tyler Chatwood and Roy Oswalt both came out fine after throwing bullpen sessions on Saturday. Chatwood, on the disabled list since Aug. 8 with a right elbow impingement, threw 30-35 pitches but was not allowed to go full-tilt. He'll throw again on Monday with more intensity. Oswalt, out since July 7 with a left hamstring strain, threw around 50 pitches and felt smooth doing so. He'll also throw again Monday.
• Wilin Rosario, who went 2-for-4 with a two-run homer on Friday night as designated hitter, returned to his catching duties on Saturday. He suffered cramps in each hamstring earlier this week and was protected from catching duty Friday. Michael Cuddyer was the designated hitter Saturday night.
Rosario continued his hot hitting with a 2-for-5 night, while Cuddyer was 2-for-4.
