"It was an awesome feeling to be back on the mound," Velasquez said. "The nerve-wracking part was the atmosphere. You're playing an opponent and before a crowd, and that's just an awesome experience. It's a good way to get back on track and a good note to start off on."
Astros director of player development Fred Nelson was on hand to see Velasquez's first start on June 18, in which he threw five scoreless innings. Velasquez came back Sunday and allowed six hits and two walks in 4 1/3 innings at Connecticut.
"He was really solid," Nelson said. "Not only did he have quality stuff -- fastball, curveball and straight change -- but he had command of them all. I don't know what he was like before [he was injured], but he was better than I had seen down in Florida while going through his rehab."
When he began his pro career in Greeneville in 2010, Velasquez's fastball was settling consistently at 88-90 mph and topping out at 94-95. So far this year, he's sitting at 90-92 and topping out at 96, though he admits adrenaline is a factor.
"It was hard to get over the surgery mentally, but now that it's all done, it's an awesome feeling," he said.
It's an awesome feeling for the Astros, too, who have high hopes for Velasquez.
"I think a lot of times when we talk about injuries, it's out of sight, out of mind," Nelson said. "You learn to live with those people not being around. They're around, but they're not competing. Rosters are set and you have plugged the holes, and all of a sudden, you look at them and they're healthy. It's like getting another new guy."
Velasquez wants to focus this year on just being healthy, though getting sent to Lexington later in the season would be icing on the cake. He plans to come into next season with some lofty goals, having already cleared some big hurdles.
"So far, I can completely say the surgery was successful and it's all positive," he said.
The Astros will soon get another player back from Tommy John surgery. Taiwanese right-hander Chia-Jen Lo, who was in Major League camp a couple of years ago, is getting some rehab innings for the Gulf Coast League Astros, and could be sent to Double-A Corpus Christi later this year.
