DENVER -- The Rockies called up right-hander Rob Scahill from Triple-A Colorado Springs and activated him for Sunday afternoon's game against the Brewers.
Technically, Scahill replaces right-hander Chris Martin, who was sent down to Colorado Springs on Saturday. Righty reliever Wilton Lopez joined the team Saturday, but the Rockies never officially activated him, meaning the club played Saturday's game with 24 players. On Sunday, they sent Lopez back to Colorado Springs and activated Scahill, who joined the team with two days' rest after throwing 36 pitches in an outing on Thursday.
Scahill, 27, is 1-0 with a 4.29 ERA in 29 Major League appearances covering 42 innings. A starter for much of his Minor League career, Scahill converted to the bullpen last year. This season at Colorado Springs, Scahill is 1-1 with a 3.93 ERA in 24 games, with extended appearances lately.
The Rockies should be getting a more versatile pitcher than they've seen the last couple of years. As he converted to relief, the Rockies asked Scahill to limit his pitch mix. Now they're letting him expand.
"I was working on fastball command, secondary command, continuing to work on my changeup, and they let me throw my curveball again, so I got that back," Scahill said. "I'm able to attack people with a four-pitch mix out of the bullpen.
"I always thought the curveball was an OK pitch for me but they wanted me, the last year and a half, to focus on my changeup and my cutter. Lately they've let me throw the curveball again."
In another pending transaction, catcher Michael McKenry was on the active roster Sunday, but he'll be placed on bereavement leave Monday for a family situation. Catcher Jackson Williams, a Giants supplemental first-round pick in 2007 who has hit .262 this season at Colorado Springs, will join the Rockies for the three-game set with the Cardinals starting Monday.
