Arlington, Texas The players' association filed a grievance Monday seeking to overturn the Anaheim Angels' suspension of left fielder Jose Guillen.
Guillen was suspended without pay for the rest of the season Sunday because of his outburst after being lifted for a pinch runner a day earlier in Anaheim. The suspension would continue into the postseason if the Angels advance that far.
The case will be heard by arbitrator Shyam Das in Oakland on Friday, the day the Angels start a regular-season-ending series against the AL West-leading Athletics.
General manager Bill Stoneman said the team would defend its move, but wouldn't go into details.
"It's something that's going to all be brought out in front of an arbitrator, and that's the appropriate setting," Stoneman said before the start of a four-game series in Texas. "Jose's conduct that followed (being lifted), that's the bulk of it. ... There was stuff seen publicly and stuff that wasn't."
Guillen was hit by a pitch opening the eighth inning of Saturday's 5-3 victory over Oakland. Manager Mike Scioscia sent Alfredo Amezaga in to pinch run.
After he walked off the field as the A's changed pitchers, Guillen tossed his helmet toward the side of the dugout Scioscia was standing in and walked to the opposite side of the dugout. He then slammed his glove against the wall.
Scioscia spoke with Guillen after Sunday night's game, calling the outfielder after finding a note on his desk with a phone number.
"Jose obviously doesn't like being in this situation of not being able to play," Scioscia said Monday. "In the meeting we had (Sunday), Jose understood what happened. I think it sunk in, the magnitude of his actions causing the suspension."
Still, Scioscia said Guillen "didn't initiate any apology."
Guillen was not with the team in Texas, where the Angels entered the series just a game behind the Athletics. Guillen's agent, Adam Katz, has declined comment.
Scioscia said the suspension "wasn't a knee-jerk reaction" and was based on more than just what happened Saturday.
Neither Stoneman or Scioscia wouldn't speculate on what will happen in the hearing, or what the team will do if Guillen is ruled to be reinstated.
Guillen, who signed a $6 million, two-year contract during the offseason, went on a profanity-laced tirade after being beaned in a game at Toronto in May, complaining that his teammates weren't retaliating for him.
Anaheim pitcher Jarrod Washburn was annoyed Guillen went public with his complaint.
