Castillo tumbled over and hung on to the ball, taking at least two bases away from Suzuki.
In the eighth, Castillo robbed Suzuki again, this time on a sinking liner.
"I was really happy to make a good play, actually two good plays, to keep the game close in what could have been big situations," said Castillo.
Though he has been a center fielder most of his career, Castillo seems to be acclimating quickly to right field.
"I'm starting to feel really good out there. I feel like I'm adapting well and feel more comfortable the more games I play," said Castillo.
Is there a big difference between the two positions?
"To me it's been all the same. There hasn't been much of a transition. In center field, I've always felt a little more comfortable just because it's a little more true," said Castillo. "You also feel like you have more room, which is a little different. It's not that different in our park because in our park, you kind of feel like you're playing center field with all the room you have. I feel pretty comfortable out there. I don't see it as all that different."
Since being recalled from Triple-A on May 22, Castillo is hitting .200, producing three singles in 15 at-bats.
"I'm feeling better and better every day. I haven't had the results I want yet, but I'm feeling better and seeing the ball well," he said.
