It was the latest tough pill fed to the lefty, who does have a winning record (4-3) that would be far better if his pitching days did not match up with some of the Buccos bullpen's poorer days.
Saturday's game represented the 10th time Locke departed with a lead. He has won four of those.
"I'm OK with that," said Locke, who was surprised to learn how often his leads have not held up. "Those [relievers] have done great all year and when they stumble, it just happens to be me this year.
"But they've won me a ton of games. [Blown leads are] a collective effect, because we're all trying to get to the same place. It'll get scary when we get rolling, the way we should."
