"I finally squared up the ball, so I'm definitely making progress and stuff like that," Singleton said. "It's definitely a great feeling. ... At this point, I'm not ready to start the season. Every day's a work in progress, but I'm getting to that point."
Houston manager Bo Porter has praised Singleton for how he's working at-bats despite the lengthy hitless stretch, as evidenced by his eight walks compared to seven strikeouts this spring. Still, Porter was happy to see Singleton put one over the fence on Thursday.
"It was a really good swing, and I've said this: He hadn't really had any hits, but the at-bats have been deep counts," Porter said. "He's putting together quality at-bats, and that's more so what we're looking at. But it was good to see him really get down through a baseball today and put a good swing on it."
