STOCKING UP: The Phillies traded outfielder-first baseman Carmelo Martinez for two minor-league outfielders the Pirates had mistakenly put on waivers.

"It's nice because it makes me feel like I still have some value," said Martinez, who hit .242 in 71 games at first base and left field. "Three Rivers Stadium is a good ballpark for me. Now I'll get a chance to play."

The Phillies get Wes Chamberlain, 23, who was batting .250 at Class AAA Buffalo, and Julio Peguero, 21, who was hitting .282 for AA Harrisburg.

Pirates General Manager Larry Doughty said he put the two minor-leaguers on waivers when he juggled his 40-man roster but thought he could revoke the waivers if another team claimed them.

"I misinterpreted the rules," he said. "We had to trade them or lose them, because we were going to lose them anyway. The waiver claims forced me to do something a little bigger than I planned to do, but I like the deal."

Chamberlain will join the Phillies now. Peguero will be assigned to AA Reading. The Phillies also will get a player to be named later.

Phillies General Manager Lee Thomas said the Aug. 3 acquisition of Dale Murphy from Atlanta made Martinez "somewhat expendable for us."

Chamberlain was considered the top prospect in the Pirates system before this season. He was the Eastern League player of the year at Harrisburg last year and has six homers and 52 RBI in 123 games at Buffalo.

METS BUSY: The Mets traded a Class A pitcher to the Royals for utility man Pat Tabler (.276). They also called up right-hander Julio Valera from AAA Tidewater and waived catcher Orlando Mercado to the Expos.
