Bundy became the first pitcher in modern MLB history to give up four home runs without recording an out, according to the Elias Sports Bureau.
In the first inning against the Royals in Baltimore, Bundy faced seven hitters without recording an out. He gave up four home runs, two walks and seven baserunners total, leading to seven runs and an exit after only 12 minutes.
Here's how it unfolded:
Royals left fielder Jon Jay led off with an infield single.
Right fielder Jorge Soler homered to center.
Third baseman Mike Moustakas homered to right.
Catcher Salvador Perez homered to center.
First baseman Lucas Duda walked on four pitches.
Designated hitter Whit Merrifield walked.
And left fielder Alex Gordon homered to right, driving in Duda and Merrifield.
And just like that, Bundy's night was done.
The right-hander has given up 17 earned runs over his past nine innings covering three starts. Even so, Tuesday was an aberration; he had given up only one home run over his first six starts of the season.
All told, the Royals had nine hits in the inning, scored 10 runs and tied a club record with four homers. Bundy (1-5) entered the game with a 3.76 ERA. He finished it with a 5.31 ERA.
The Royals scored five more to win Tuesday's game 15-7.
Bundy had been dealing with a tight groin leading up to the start, and after the loss, said he physically was fine, but "just not executing the pitches I need to right now."
"I was leaving pitches right down the middle and they were hitting them over the fence. I got us in a 7-0 early hole and couldn't climb out of it," Bundy said. "It seemed like ([I'd throw] ball one, strike one and then -- homer. I just have to work ahead of guys and I haven't been able to do that the last 3 starts."
