Tracy plans night off for Belisle

CINCINNATI -- Matt Belisle, who recorded four key outs Friday night against the Reds, may get the night off on Saturday. He has pitched in four straight games and has 23 appearances on the season.

"I'm having days where I [look at certain members of my bullpen] and I have to say to myself, 'You can't do it -- not under any circumstances,'" Colorado manager Jim Tracy said. "And for me, Matt Belisle is teetering on that today. You look at [all the work he got] in Miami and what he did last night ..."

The Rockies are on pace to surpass 150 bullpen innings pitched by the end of May.

"If I'm going to be able to set my bullpen up and use it the way I want to, we're going to have to get more innings from our starters," Tracy said. "It's that simple."

Cuddyer back in starting lineup vs. Reds

CINCINNATI -- Michael Cuddyer, scratched from the lineup Friday due to a stiff neck, started in right field and batted sixth against the Reds on Saturday night. Colorado manager Jim Tracy said Cuddyer was feeling stiffness Wednesday night in Miami but gutted the game out. On Friday, however, the pain was too much to play through.

"He was involved in batting practice [Friday], but you could tell in his face that he was in quite a bit of discomfort," Tracy said. "We tried to work on him in the clubhouse, but we had to scratch him. He's in a much better place today. He was out taking BP this afternoon, he's got full range of motion, his head's moving around the way it should be -- so we've got him back in there today."

Cuddyer is hitting .276 with four home runs and 27 RBIs in 43 games this season.

Tulo heating up as May heats up

CINCINNATI -- Troy Tulowitzki started slow in the month of May but is heating up toward the end. The shortstop hit just .196 (11-for-56) in 17 games from May 1-20, but in his last four games is hitting .438 (7-for-16) with two home runs, two doubles and seven RBIs.

He went 3-for-4 against the Reds on Friday night for his second three-hit game of the season and his first since April 13. He has five hits in his last two games -- the most he'd had during a two-game stretch this season and the most since Aug. 6-7, 2011, when he had five against Washington.

"I think he's back to his old self," Rockie manager Jim Tracy said. "We've seen in the last few days what our offense is capable of when [Carlos] Gonzalez is doing his thing and Tulowitzki is following up."

Tulowitzki has also doubled in back-to-back games -- this after going going without any doubles through his first 19 games in May. Tulowitzki set a career high with 36 two-baggers in 2011 and has 68 over the last two seasons.

The Rockies, winners of two straight, have scored 24 runs in their last four games.

"Six runs has to be enough [to win games]," Tracy said. "Believe me when I tell you that if you're averaging six runs at the Major League level, that's a lot of runs."

Worth noting

The Rockies, winners of two straight, are seeking their second three-game winning streak of the season and their first since April 17-20, during which they took two games from San Diego and one from Milwaukee.
