The Royals defeated the A’s 8-4 on Sunday, finishing a three-game sweep at Kauffman Stadium. Although he had just one at-bat, first baseman Vinnie Pasquantino had a team-high three RBIs as the Royals moved 10 games above .500 at 29-19.

Pasquantino wasn’t in the starting lineup, but with the Royals holding a 4-1 lead in the bottom of the sixth inning, he was called upon to pinch-hit with one out and the bases loaded. Pasquantino delivered his first career triple, a liner down the first-base line as the Royals broke the game open.

On Saturday, Royals manager Matt Quatraro told Pasquantino to button it.

That wasn’t a command to keep quiet. Quatraro thought Pasquantino didn’t need to keep the top two buttons on his jersey unbuttoned.

“I’m no fashion icon, I kind of know that for sure,” Quatraro quipped before Sunday’s game. “But when you look like that, you need somebody to say something to you.”

Pasquantino heeded his manager’s opinion mid-game on Saturday and left just one button undone. He then delivered an RBI single that snapped a zero-for-14 skid. Then came Sunday’s three-run triple, which came with Pasquantino’s jersey buttoned to the top.

“Yeah, I was fully buttoned up today,” Pasquantino said. “I looked like a businessman out there. That’s how I felt. My chain was kind of tucked in. I couldn’t even feel that I had it on today. So I guess we found something that’s working right now. We’ll stick with it.”

Pasquantino is now hitting .667 since the fashion change. (See? A stat for everything.)

“Well, I had both buttons up today,” Pasquantino corrected. “So technically speaking, hitting 1.000 with both buttons. I don’t think that’s gonna last, batting 1.000. But hey, maybe.”

Heck, Pasquantino has a 3.000 slugging percentage and has only hit triples while ditching the buttoned-down look.

When he saw the runners being waved home, Pasquantino decided to go for the triple.

“He runs like a truck,” Salvador Perez quipped. “Sorry Vinnie. Now I need to get one.”

Pasquantino took Perez’s joke as a compliment.

“I’m gonna assume like an 18-wheeler going downhill with no brakes or something,” Pasquantino said. “So thank you, Salvy.”
