LEXINGTON, Ky. - Two days after signing a prorated $28 million contract with the pitching-starved New York Yankees, Roger Clemens wore pinstriped pants and a Yankees cap while throwing from a mound yesterday at the University of Kentucky.

"The arm feels good," Clemens, 44, said after the workout. "Right now, I've just got to get that soreness that every pitcher understands. I've got to get it in my legs and out as quick as possible so that I know I can handle the stress of a major-league game."

The workout took place in the same city where the seven-time Cy Young Award winner began his comeback last year. Then a member of the Houston Astros, Clemens had his first tune-up with the single-A Lexington Legends, for whom his son Koby plays third base.

But as a member of another organization, Clemens couldn't work out at the Astros' facility this time. Instead, the future Hall of Famer threw for more than an hour at Cliff Hagan Stadium, which allowed him to attend Koby's game down the road later in the day.
