"It shows he's trying to get better," Melvin said. "If he thought there were a few pitches up in the zone, and that doesn't sit well with him, that's a good thing. I'm glad to hear he thought there were some issues with it, but from our perspective, I thought he threw the ball well."
Griffin did well on paper, allowing just one run -- credited to Rockies designated hitter Nolan Arenado, who tagged him for a second-inning solo shot -- on three hits with no walks and one strikeout. All other outs came in the air, though, leaving Griffin believing there is plenty work to be done.
"It could've been lot better if I kept the ball down," he said. "I got a lot of fly balls and like to see more ground balls. Mentally I have to be more focused, but, overall, I was aggressive going after guys, and like that I didn't walk anyone.
"I don't like giving up home runs, but I hate walking people more than giving up home runs. I'd rather have the guy have to beat me than give him a free pass, especially right now. In the season, if it's a certain situation, obviously you want to be smarter about it, but right now I'm just going after guys trying to get ready."
Griffin, most likely pegged for the fourth spot of the A's rotation, threw 48 pitches Sunday and felt good about the progress he was making toward being season-ready. That process, he said, becomes easier with each pitch he throws.
"I felt like I was sharpest in the last inning, making more quality changeups and having a better feel for the curveball," he said. "I just primarily want to get my fastball command going, because that's the most important one."
