Minor league outfielder Matt Lipka received death threats for breaking one of baseball's unwritten rules.

In the ninth inning of a no-hitter, he bunted for a single to break up a no-hitter of his team's 3-0 loss Tuesday to the Hartford Yard Goats, according to a NJ.com report.

Lipka's team, the Trenton Thunder, are a minor league affiliate of the New York Yankees and the organization is investigating social media death threats sent to the 27-year-old Lipka to assure his safety.

Fans of the Hartford Yard Goats, an Eastern League affiliate of the Colorado Rockies, were furious after Lipka opted to bunt to break up the potential no-hitter.

Lipka's successful bunt up the first base line was the only hit of the game for the Thunder. Yard Goats players were unhappy right afterwards and the tension from the bunt led to both benches being cleared.

“It is what it is,” said pitcher Rico Garcia, who threw six no-hit innings and striking out 11, told MILB.com. “(Lipka) was doing what he had to do. And we were really passionate about getting the no-hitter. It is what it is. I can’t really speak for what he was trying to do or what he was trying to accomplish. It’s unfortunate we couldn’t get the no-hitter. Emotions were high after.”
