DENVER -- When manager Walt Weiss took a look at the Rockies' upcoming schedule, he knew he needed to map out a plan for his team's long-term future.
Before the Rockies played the Astros in game six of a grueling stretch of 17 games in as many days, Weiss decided to call right-handed reliever Rob Scahill back up to the big leagues. Scahill, 25, has already appeared in two games this year, and will attempt to extend his streak of 5 1/3 scoreless innings.
Weiss knew he needed to bring on a 13th pitcher to make sure his pitching staff had the endurance for this stretch.
"Our philosophy was before the season started, when in doubt, we need to protect our pitching and this is one of those times," Weiss said. "It's one of those times in the schedule and in the season where our bullpen's been taxed."
The starting pitcher has lasted six innings or fewer in three of the Rockies' last five games, forcing the Rockies' coaching staff to dig deep into its bullpen. Such heavy use of relievers, along with the tall order of games that lies ahead, convinced the first-year manager to make the move Wednesday.
Though Weiss declined to say how long he expects the righty to stay in the big league clubhouse, Scahill has shown promise. In 2012, Scahill pitched 8 2/3 innings over six games and finished his rookie campaign with a 1.04 ERA.
Scahill will likely be used out of the bullpen to face multiple hitters, rather than face just one or two batters in an appearance.
"He's been real good at pitching to the bottom of the [strike] zone, his stuff has never been a question," Weiss said. "Sometimes his command will get away from him, you see the big misses up. We haven't seen that, I think he's taking some major strides. He's always been a great competitor, and now he's got the command to go along with his makeup and his stuff."
