DENVER -- The Rockies used a season-high 22 players in their 13-inning win over the Dodgers on Saturday, so it was no surprise that Rockies manager Jim Tracy deemed some players "off limits" on Sunday.

Chief among them was right-handed pitcher Edgmer Escalona, who was the only relief pitcher who didn't see action on Saturday. Escalona, though, threw 61 pitches in long relief in Friday's opener, and he's thrown 118 overall in the last five days.

"Escalona cannot be touched," Tracy said.

The manager said right-hander Josh Roenicke, who threw 41 pitches over two innings in victory, would be used only if the Rockies were "absolutely down to cinders."

"You maybe reconsider him for a very, very short stint," Tracy said.

Sunday's starter, veteran right-hander Kevin Millwood, is the right pitcher to follow a marathon game, according to Tracy.

"He knows what took place yesterday," Tracy said. "Millwood's standing in [the dugout] knowing, 'Whether I'm good or not, I've got some work to do [on Sunday] because there won't be a lot of help for me early.' I don't have to walk in and tell him that. I guarantee you that. He's already aware of that."

Betancourt in midst of another dominant run

DENVER -- Lost in the fray of the Rockies' 7-6, 13-inning win over the Dodgers on Saturday was a dominant performance from reliever Rafael Betancourt.

The hard-throwing righty followed that up with his second save in Sunday's 5-3 series-clinching victory.

On Saturday, with the game tied in the ninth inning, Betancourt retired the first three hitters he faced with a pair of groundouts and a harmless fly ball.

The clutch outing -- his first appearance in seven days -- was just another chapter in a string of dominant second-half performances from Betancourt, who has not allowed an earned run since July 7, a span of 15 innings. During that stretch he has given up just five hits, with 26 strikeouts against one walk.

It is a similar stretch to last season, when Betancourt gave up just four earned runs in 23 2/3 innings after the July 31 non-waiver Trade Deadline. During that same time period in 2009 -- when he joined the Rockies after seven seasons with the Indians -- he gave up five runs in 21 2/3 innings.

"It's a long season, and you're going to go through bad times, good times," Betancourt said. "That happens. That's what I like to do. If I'm struggling, I like to be able to come back and do what I need to do. I see the results from that, because I never give up. I keep working hard."

Several weeks ago, with Betancourt struggling, Rockies manager Jim Tracy was experimenting with hard-throwing lefty Rex Brothers in the setup role.

"I needed to afford myself the opportunity to massage this guy and get him feeling back to being himself again, and then move him slowly back to that [eighth-inning] area," Tracy said.

Betancourt had no problem with the move.

"This is teamwork," he said. "They took me out of the [setup] spot because I was struggling, and I understand that. They needed to put someone else in there to get people out.

"I have to be able to see what I did wrong, see what I can do to make it better and be able to come back and get my spot."

Betancourt still isn't occupying the setup role, but only because he is temporarily filling in as closer until Huston Street returns from the 15-day disabled list. No matter when he has pitched, the veteran right-hander has been striking out hitters at a high rate. He has punched out 10 in his last 7 1/3 innings.

"I just try to throw strikes," Betancourt said. "It's one of my goals when the season starts. I have many goals ... but the first goal I want to manage is, I need to throw strikes."
