Martin Perez struck out two over two scoreless innings Monday against the Rockies.
Perez threw 16 out of 27 pitches for strikes. One of his strikeouts caught Troy Tulowitzki looking. It was a very favorable first impression as he attempts to win a rotation spot. Justin Grimm, who is also in the mix for the fifth spot, gave up three runs on four hits and a walk over two innings.
