"As soon as I did it, I was kind of in shock," Barton said of the injury, which occurred at a friend's apartment in Huntington Beach, Calif., on Sunday night. "I felt my head, looked down and saw a handful of blood."
First baseman Wes Bankston was called up from Triple-A Sacramento and inserted into the lineup for Saturday's game against the Yankees, batting eighth. This is the second time on the big league club for Bankston, who started nine games and batted .294 during a call up earlier this month.
A's manager Bob Geren said he has "mixed feelings" about Barton's injury. Barton said the pool was more shallow than he thought.
"Obviously, the injury could be worse," Geren said. "I'm upset about it a little bit. It seemed to be a careless mistake that hurt the team."
Barton was expected to play in Friday's series opener, but the pain in his neck worsened during batting practice. He said the staples will be removed on Wednesday and he can be ready to play in less than a week.
"I want to play," said Barton, who was batting .224 with three home runs and 25 RBIs in 36 games. "It's my job to play. I have to take responsibility for my actions. It was a freak accident, and I have to deal with it."
