Jim Palmer says he is thinking about trying to become a major league pitcher again.

"My arm is much better now than the last year I pitched," Palmer, 45, said Monday in Denver, where he was on a promotional trip for Jockey. "I'm going to start throwing three days a week next week in Baltimore. I'll know what I can do in about three weeks.

"I can always be a broadcaster and I just signed a new three-year deal with Jockey, but nobody has ever come back after being inducted into the Hall of Fame."

Palmer was inducted into the hall this year in recognition of his outstanding 19-year career with the Baltimore Orioles that ended in 1984. In the course of his career, he amassed a 268-152 record, had a 2.86 ERA and struck out 2,212 batters . . .

The Orioles added right-handed pitcher Francisco de la Rosa and outfielder Luis Mercedes to their roster, which now stands at the maximum of 40 players.

Mercedes, 22, won the Eastern League (Class AA) batting title in 1990 with a .334 average for Hagerstown. De la Rosa, 24, was 9-5 in 23 games for Hagerstown and was promoted to AAA Rochester, where he pitched two games.

Baltimore also made a minor league trade, sending Marty Brown (Rochester) to the Cleveland Indians for outfielder Jeff Wetherby (Colorado Springs).
