New addition Logan makes impact in Rox 'pen

CINCINNATI -- Left-hander Boone Logan has changed the dynamic of the Rockies' late-innings bullpen, manager Walt Weiss said.

Logan (1-1, 3.75 ERA) gave up two runs in his latest outing, including Joey Votto's ninth-inning homer in a 4-3 loss to the Reds on Friday night. But through Saturday he had nevertheless pitched scoreless ball in 11 of his 14 outings this season. The Rockies have had to work through Rex Brothers' consistency issues, so Logan's role is more important than originally planned.

"Boone has been great for us," Weiss said. "When we signed him, we were looking for another left-hander to pitch late in games with Rex [Brothers]. He's been huge for us. He's changed the dynamic of our bullpen."

Logan had surgery to remove bone chips and correct a bone spur on his left elbow in October, after making 61 appearances last season for the Yankees (5-2, 3.23 ERA). The Rockies were careful with Logan. They slowed down his Spring Training and had him pitch two games with Triple-A Colorado Springs before activating him.

Weiss has been happy with Logan's pitches.

"That would be great if there's another level there," Weiss said, "but if he stays where he is, I'll take that."
