NEW YORK (AP) _ Baseball trimmed Pirates pitching coach Pete Vuckovich's suspension for bumping an umpire and using ``foul language'' from three games to two on appeal Wednesday.

Vuckovich was originally penalized by Frank Robinson, major league baseball's vice president of on-field operations, for an argument in a game against the New York Mets on June 23.

Vuckovich was ejected by first-base umpire John Hirschbeck for arguing a balk call against right-hander Bronson Arroyo in the Pirates' 9-0 loss at the Mets.

Paul Beeston, baseball's chief operating officer, ruled on the appeal, and Vuckovich will start serving the suspension Thursday.
