SCOTTSDALE, Ariz. -- The D-backs lost their shutout in the ninth inning of Wednesday's 6-2 win over the Rockies, but that didn't take away from a second straight impressive day turned in by the pitching staff.
De La Rosa did a nice job pitching around an error in the second inning and had a really good tempo.
Other noteworthy things from Wednesday's game:
• Two of the team's three top pitching prospects -- Aaron Blair and Braden Shipley -- tossed two scoreless innings apiece.
The pair were drafted with the club's top two picks in the 2013 First-Year Player Draft.
"I'm sure it was exciting for you guys and the fans to get to see Blair and Shipley," D-backs manager Chip Hale said. "Everyone has been so excited to see what they look like -- young guys in the organization. They really threw the ball well."
• Catching prospect Peter O'Brien rapped out a pair of hits in three at-bats and also played well behind the plate.
"The most important thing for us -- we know he is going to swing the bat and do some damage -- we're really watching that catching," Hale said. "I asked the umpire at one point how he felt with him in front of him and he said he did a good job and was showing him the ball well. He did a good job with the pitchers. This guy has really, really improved behind the plate. He's bilingual, which is great with our staff, he helps out a lot of guys. He's a really, really good teammate."
• Shortstop Walter Ibarra was impressive at the plate, going 3-for-3.
• Third baseman Jake Lamb committed an error at third when he tried to rush what could have been a potential double play.
"He just tried to be too quick," Hale said. "It was a double-play ball. It's something we talk about all the time, to slow the game down."
• Non-roster invitee Jordan Pacheco went 1-for-2 and Hale pointed out that Pacheco's ability to catch as well as play third, second, first and the outfield could make him a valuable utility player for a National League team.
