Roger Clemens has always liked to show the world who's boss.
The multiple Cy Young award winner and World Series champion is going to try to prove he's still got it this Saturday as he starts his latest baseball stint with the Sugar Land Skeeters.
Before the 50-year-old Clemens committed to the job, though, he was seen showing off his skills in another locale. Baseball America caught him throwing a bullpen at Illinois-Chicago's Les Miller Field last Thursday, although not likely in the performance that had some people saying Clemens can still throw 87 mph.
The Rocket looks laid back in this go-around, but check out the video below to see him popping them in there like he's 15 again.
