"K.K.'s hit, obviously, to be able to separate it right there, we needed that," Rays manager Kevin Cash said.
The speedy Rays center fielder finished second in the Major Leagues in triples in 2015 with 12 (Minnesota's Eddie Rosario had 15). Kiermaier got his first triple in the Rays' second game last season and had logged three by May 20, but none was bigger than the one he hit on Friday night.
Kiermaier laced his triple down the right-field line, chasing home Evan Longoria, Steve Pearce and Logan Morrison, who had been on first. Kiermaier has three triples in three career games at Comerica Park.
"It's just so spacious out here -- probably the biggest outfield in all of baseball," Kiermaier said. "I know there are a couple in the National League, but this is definitely the biggest in the American League. It's just all about placement when it comes to triples. ... I'd like to hit more, but it's all about finding gaps for that right-field line."
