Teahen got his second inside-the-parker on Thursday night, when he belted a long drive to right-center field against White Sox left-hander Boone Logan. Teahen took a head-first dive across the plate just ahead of the tag.
"When you slide in, it's awesome, because it's such an exciting play that the energy you see in your teammates and fans and everything is just pretty cool," he said.
There was a moment of hesitation on the part of relay man Alexei Ramirez and on the part of Teahen, too.
"[Third-base coach Luis Silverio] was waving me all the way to third so I was going hard, but I slowed up a little at third because I thought, for sure, I'm stopping here. But he sent me and it worked out good," Teahen said.
His first inside job came on May 27, also at Kauffman Stadium, against Twins closer Joe Nathan.
"It was down the left-field line and Delmon Young came over, kind of slid for it, and missed it and didn't really hustle after it," he said. "It's exciting when you see you have a chance to try it."
Teahen took a head-first slide into the plate that time, too, but only because his legs got a bit wobbly along the way.
"I decided to dive because I didn't think my legs were going carry me through it," Teahen said.
He became the first Royal to have two inside-the-park homers in one season since Brian McRae in 1992.
"And it's just the first half," Teahen said, laughing. "I'm on pace for at least four."
He still wouldn't have the team record, though. Willie Wilson had five in 1979.
