SCOTTSDALE, Ariz. -- After a pair of impressive performances, D-backs right-hander Rubby De La Rosa struggled with his command in a rocky start against the Mariners.
De La Rosa, who his battling for a spot in the rotation, only gave up three runs in three innings Saturday, but he was fortunate that was all the damage the Mariners did considering he walked four and hit a batter.
"I was rushing a little," De La Rosa said. "It's not a big deal. I tried to do too much, tried to throw perfect pitches. I think that's what made me rush a little bit."
De La Rosa retired the Mariners in order in the first before losing his command in the second.
"The first inning he wasn't [rushing]," D-backs manager Chip Hale said. "After that he definitely was rushing or something was different about it because he didn't throw as many strikes. We're just seeing some chinks in the armor. We're going to have to fix it. It's our job."
