Zack Greinke gave up four runs (three earned) on 11 hits and a walk with six strikeouts over seven innings against the Rockies.
Greinke had a chance to become the NL leader in wins with nine, but he ended up with the no-decision Saturday to remain undefeated at 5-0 in seven starts against divisional foes on the year. Greinke will have another shot at his ninth victory when he takes the mound next Thursday in Cincinnati against the Reds.ANALYST: Michael Pichan
Miguel Castro will open the season in the majors.
Castro flew under the radar in the minors last season, but is making the rare jump from A-Ball to the majors. This is thanks to his (likely) temporary move to the bullpen for the Spring, which enabled his stuff to tick up a bit in shorter outings. He's likely next in line to receive saves should Brett Cecil fail, and the 20-year old is worth keeping an eye on. Analysis: Ben Diamond
