An offseason full of trades and free-agent signings on the Major and Minor League levels gave the Rockies pitching depth that is there to seamlessly fill the gaps when the unexpected injury takes a pitcher out of commission.
"[Pitching depth is] exactly the reason we did some of the things we did this winter," manager Jim Tracy said. "We're mindful that pitching at altitude is a little different than pitching in a lot of other places, and so depth is very necessary."
In addition to new acquisitions currently on the Major League club, including Guthrie, Jamie Moyer, and Drew Pomeranz, the Rockies have four new pitchers with Major League experience pitching for the Triple-A Sky Sox in Alex White, Carlos Torres, Guillermo Moscoso, and Tyler Chatwood.
On Saturday, Moscoso, 28, left the Sky Sox to start for the Rockies in place of Guthrie. The right-hander did not have a great Spring Training, posting a 7.36 ERA in four appearances, and his Triple-A season has not been stellar at 1-3 with a 7.91 ERA through his first four starts -- "There haven't been too many moments of brilliance for me to speak about," Tracy said -- but it's his day to pitch, and he has some pedigree with the A's, where he was 8-10 last season with a 3.38 ERA in 23 games, 21 of which were starts.
"This is a real nice test for Guillermo Moscoso," Tracy said. "In this case, you place an awful lot [of faith] on what took place when he was playing competitive games at the Major League level during the course of the regular season with a lot of things on the line. And his numbers last year were impressive, so I'm anxious to see where this goes."
