Worth noting

• Left-hander Brett Oberholtzer and righties Chad Qualls, Peter Moylan and Matt Albers all pitched in a "B" game against Astros Minor Leaguers on Wednesday morning. Oberholtzer threw almost 70 pitches and recorded 15 outs, working specifically on getting more consistency with his curveball.

"It's not taking away from anything I do well, like the fastball, changeup and moving the ball and changing speeds," Oberholtzer said. "I got a lot of ground balls today with my fastball and changeup and quite a few strikeouts with the curveball. That's the direction I want to go. I know it's still going to take a little bit of time to get it to where I want it to be, but there's still time."

The other three pitchers, all relievers, threw one inning apiece.

• Williams has been impressed with all of the young arms in camp, as well as the state of young pitching around the league.

"I always joke around, but it's true: If you're in a bullpen in the big leagues not throwing 97 [mph], you're not going to be around. Bigger, faster, stronger, and everybody's throwing harder, and it only pushes me to go harder. I'm a low-90s guy. I want to be up with those guys, but I'm 32, and they're 21."
