The Astros trailed 1-0 and were on the verge of getting out of the sixth unscathed, until Gattis' glove made contact with Paulo Orlando's bat.
"I guess [the bat] hit my glove before the ball," said Gattis, who was behind the plate for starting catcher Brian McCann's day off. "It happens. I've got to keep my glove back further. I guess I just reached for the ball a little bit. It's frustrating. I need to give him more space."
Astros starter Mike Fiers nearly worked out of a jam in the sixth after he loaded the bases by walking Mike Moustakas and Brandon Moss and giving up a single to Eric Hosmer. With two outs, Fiers quickly got ahead of Orlando, 0-2. Two pitches later, Orlando fouled a ball off, but went to first on Gattis' interference, allowing Moustakas to score for a 2-0 Royals lead.
In the eighth, the Royals went ahead 3-1 when Salvador Perez scored on a passed ball. Gattis was expecting a slider, but Jandel Gustave threw a fastball, which crossed up Gattis.
"There was a mix up," Gattis said. "Me and Gustave had a mix up, and that was that. I'm frustrated with the way it happened."
