HOUSTON -- Michael Bourn was positive he was safe at first base. So was Astros manager Brad Mills. Umpire Alfonso Marquez disagreed.
Marquez called Bourn out on an extremely close play at first base in the ninth inning of Houston's 2-1 loss Saturday, after the outfielder hit a grounder to San Diego shortstop Jerry Hairston Jr. Bourn jumped in protest and Marquez ejected him immediately.
"I thought I was safe," Bourn said. "It was bang, bang."
"From what I saw, he looked safe," added Mills. "It happened so fast."
It was difficult to judge from the replays whether Bourn was safe or not.
Bourn was leading off the bottom of the ninth with Houston trailing by a run.
"Everything's been going wrong for us," said Bourn, speaking calmly in the Astros' clubhouse. "That could have changed the game. I lost my temper."
There could be further repercussions because it appeared that Bourn may have bumped Marquez.
"I think I did," Bourn said. "I wasn't trying to. He said, 'Don't bump me.' I wasn't trying hit to him."
Did the Houston center fielder expect to be suspended?
"I might, I don't know," he said. "That's up to Major League Baseball. I know I'll probably get a fine."
Bourn was asked if he thought he got his money's worth out of the ejection.
"Probably not," he said. "I left too early."
Bourn departed almost immediately after being ejected.
Mills said he did not see Bourn bump into Marquez.
"As soon as it happened, I'm fighting to get out of the dugout," Mills said.
Mills added that Marquez told him that Bourn did not beat the ball to first base.
