Perhaps Josh Willingham should request more correspondence from the commissioner's office.

After receiving a one-game suspension from Major League Baseball for his "inappropriate conduct" toward umpire Bill Miller over the weekend, Willingham responded Monday night with the best game of any A's hitter this season.

He smacked a three-run homer off C.J. Wilson and drove in five runs to pace the A's 7-2 victory over the Texas Rangers in the opener of a three-game series at Rangers Ballpark.

Willingham was ejected from Saturday's game against Kansas City for arguing a called third strike and then bumping Miller during the exchange. He learned of his suspension Monday afternoon, but because Willingham is appealing the decision, he is eligible to play until his appeal is heard.

"I'm glad he appealed it," said A's starter Trevor Cahill, who improved to 6-0. "That's the guy we've looked to put the ball out of the ballpark once in a while."

The five RBIs are the most by an A's player this season, and Willingham's production was needed because the A's didn't swing the bats as well as the score indicated.

They notched just four hits but benefited from eight walks, including five issued by Wilson (4-2).

After Wilson walked Daric Barton and Conor Jackson with two out in the third, Willingham connected for a three-run shot -- his team-leading sixth homer.
