Boone Logan had struck out over a third of his batters entering Monday.

PHILADELPHIA -- Rockies left-hander Boone Logan went into Monday afternoon's game against the Phillies having been scored upon in just four of his 17 appearances, with at least one strikeout in 12 appearances.

Logan was striking out 35.7 percent of opposing batters, the third-highest such rate in the National League. The strikeout rate was the highest of any left-hander entering Monday's games.

Logan has been consistent even though his game action hasn't. For example, Logan went from May 9 to May 16 between appearances, then didn't pitch again until May 21.

"It doesn't mean I haven't been warming up to come into games," Logan said. "A lot of times, a game just doesn't pan out. It doesn't fall into place, like an inning is starting with a lefty or we get through an inning. There are a lot of factors. The thing about being a lefty is you've got to wait for lefties to come up, and there are fewer lefties in a lineup, so you're not going to be in there on a regular basis.

"But when I'm getting warmed up, I'm staying loose, even when I doing get into the games. So I stay sharp that way."

Culberson puts spring practice to use at third

COL@ATL: Culberson fields and fires a dart to first

PHILADELPHIA -- During Spring Training, the Rockies asked infielder Charlie Culberson to dust off skills at third base he had not used since 2009, when he was a Class A player in the Giants' system. There was quite a bit of dust then, but now Culberson is playing a clean third in the absence of the injured Nolan Arenado.

Culberson made his third straight start at third on Monday against the Phillies, after going 3-for-10 as the Rockies dropped two of three in Atlanta.

"I played one game at third last year in Colorado Springs, but this year I had an idea I was going to do everything," Culberson said. "The first game I made a couple of throwing errors. From then on, I made one error the rest of Spring Training at third. I had 40, 50, 60 innings over there.

"I knew my role was to play wherever they needed me to play. I worked with Stu [Cole, the Rockies' third-base coach] a lot and with Vinny [Castilla, a special assistant] and picked Nolan's brain a lot, too."

Culberson entered the Atlanta series with a .174 batting average but had contributed late in some games, most notably with a walk-off, pinch-hit homer in the ninth inning on May 3 against the Mets.

Rockies manager Walt Weiss has praised Culberson for staying ready offensively. Weiss, who used Culberson in the outfield last year in a pinch, also believed Culberson's athletic ability would play anywhere, third included.

"He's athletic enough, talented enough, that his skill set is in place to be a good defender, so I wasn't too concerned," Weiss said.

Worth noting

• Rockies left-hander Brett Anderson returned to Denver on Monday to have the pins removed from his left index finger.

He sustained a fracture to the finger on April 12 and has not pitched since. However, the removal of the pins allows him to crank up his rehab. Anderson is eligible to come off the 60-day disabled list June 12.
