Bradley grounded into a double play, but thought he beat the relay throw. He argued with first base umpire Angel Campos and kept exchanging words while leaving the field.
Texas manager Ron Washington came out to discuss the play and left after a few moments. Moments later, Campos signaled an ejection -- it was the fourth time Bradley was ejected this season.
Bradley, who has been bothered by a lower back sprain, sprinted back from the dugout back onto the field and yelled at Campos, and first base coach Gary Pettis stepped between them.
Umpire crew chief Tim McClelland ran down the line from home plate, and Washington came back out to help intercede as Pettis pushed back Bradley.
Bradley eventually left the field as the Oakland crowd booed. The one-time A's outfielder raised both hands while he walked down the tunnel and to the Rangers clubhouse.
