Tuesday was a bad day to be a Kim for Colorado, unless the Day was Zach.

Byung-Hyun Kim, slotted to be the No. 4 starter, came out of the Rockies' 6-6 tie against the San Francisco Giants at Hi Corbett Field because of a strained right hamstring.

Sun-woo Kim, one of three pitchers considered in the hunt for the No. 5 slot, also suffered a right hamstring strain and, instead of starting today's game against the Arizona Diamondbacks, will pitch in a simulated game with the hope he can build arm strength without aggravating the injury.

Zach Day is the likely pitcher to move up in the rotation:

Day has been the in-house favorite for the fifth starter spot since spring training opened, and though he gave up four runs in five innings Tuesday, he got only one flyball out.

He struck out six and got eight outs on groundballs. It was a solid follow-up to the strong five innings he worked Friday against Arizona.

Day, however sports a 9.75 ERA in 24 spring innings. The eleven walks in that span needs to improve. I'm not sure there's much he can do about the home run every eight innings.
