Roger Clemens is having fun preparing for his Saturday start for the Sugar Land (Texas) Skeeters, an independent team in the Atlantic League, and the 50-year-old said it might be a one-time appearance.
Clemens said his fastball has been between 84 and 87 miles per hour, and he "might" reach as high as 88 on Saturday.
"I've got aches and pains that I've never had before at this age, and when you ramp it up just a little bit, that's where it goes," Clemens told Ryen Russillo on ESPN Radio on Tuesday. "I'm not looking any further past Saturday."
Whether he makes a second appearance for the Skeeters could depend on how well he pitches Saturday.
"Here's my stance on it. I'm getting more ribbing at home from the boys than anybody, and friends and other guys who are playing ... they're getting a good laugh out of this," Clemens said. "If I don't do well, you can't expect another start for sure. Mufasa isn't ready to give up the kingdom just yet.
"If do well, I might have some bragging rights at home. So we'll see, we get this little one-on-one games when I throw batting practice, so we'll see what happens.
While he has been given a teaching/advisory role with the Houston Astros by owner Jim Crane, it doesn't sound as if Clemens has any designs of working toward a major-league pitching appearance. He's focused on his family, foundation and the role with the Astros.
"Being as active as I am, it keeps me young and like my mother and grandmother said, there's never going to be any grass growing beneath my feet. I'm going to stay moving."

--Mariners right-hander Felix Hernandez is regarded as one of the best pitchers in baseball. That means he'll be most expensive to re-sign when his contract expires at the end of the 2014 season.
But Hernandez was convincing in an interview with Sports Radio KJR on Tuesday in a spot that focused mostly on his recent perfect game. Hernandez said he had only one other no-hitter in his life at age 10.
"Seattle has been unbelievable," he said.
"I think we can win championships here in Seattle," Hernandez said. "...We're going the right direction."
Asked what the chances he'll sign before his contract expires, Hernandez said "You guys will be happy. I promise."
