Machi ejected after disputing balk call in eighth

OAKLAND -- Giants reliever Jean Machi was ejected from Tuesday night's 6-1 loss against the Oakland A's, becoming San Francisco's second player to get tossed this season.

Machi apparently was upset by the balk that plate umpire Angel Hernandez called on him during the eighth inning. The balk advanced Nate Freiman from second to third base, making it easier for him to score on Alberto Callaspo's single.

Machi was ejected after the inning ended on Nick Punto's double-play grounder.

Center fielder Angel Pagan was the other Giants player to be ejected from a game this year, receiving the thumb in an April 21 game at Colorado.
