Nothing like an early morning shot of The Rocket to get your day going. Just ask Astros pitcher Brett Oberholtzer, who joined his fellow pitchers and the team's catchers in getting to hear from seven-time Cy Young Award winner Roger Clemens when he made his first appearance at Astros camp on Wednesday. "The energy filled the clubhouse, and it woke us and got us going if the coffee didn't," Oberholtzer said. "It was a great morning." The day was only beginning for Clemens, who's in his second year as special assistant to the general manager. Clemens arrived at Osceola County Stadium on Wednesday for a two-day stay in which he addressed the team and talked individually with pitchers after they threw in the bullpen. "I love it because when I was young, I was fortunate to have some veteran players around that I wasn't afraid to ask pointed questions," Clemens said. "I paid attention to detail and enjoyed watching. If I can fire them up and get them all excited and still give them a little reality ..." Clemens, who plans another stint at camp next month at some point and plans to throw a round of batting practice, said the team's young pitchers need to step up this year, a point he made when he addressed the team. "It was pretty straightforward," he said. "We talked about the expectations that there's more than a handful of guys that have an opportunity, and they need to take a big step forward. Spring Training, everybody's all giddy right now, and then you start the season and everybody gets punched in the face, and it's not a lot of fun. I think they're taking the kid gloves off them a little bit and asking a lot of them to step up." Clemens, 51, took some time to work with young pitchers like Jarred Cosart and Josh Fields, and veterans like Jerome Williams and Lucas Harrell, who spent an extensive amount of time on the mound with Clemens.
