Andrelton Simmons suggested tickling as a way to rouse a smile from stone-faced Alex Kirilloff.
But even that extreme measure seems destined to fail, considering even the rookie's first two career home runs Friday weren't enough to elicit a showing of joy.
"No one knows how to really get to him or to make him laugh or smile yet," Twins manager Rocco Baldelli said. "I think our infielders are coming up with ideas."
Nelson Cruz ended up coming up with a solution, as the veteran team leader demanded Kirilloff smile after his first homer that helped the Twins to a 9-1 victory over the AL Central Division-leading Kansas City Royals.
"He just was telling me to lighten up," Kirilloff said, "and smile for the camera."
With a roster loaded with outfielders and infielder Miguel Sano readying to rejoin the team from the injured list, Kirilloff had plenty of motivation to keep his level head and perform Friday in front of another sellout Target Field crowd of 9,982.
The Twins' top prospect was a bit of a surprising absence from the Twins' Opening Day roster, which team president of baseball operations Derek Falvey attributed to shaky timing in his at-bats. So the Twins kept him at the alternate site in St. Paul, not even putting him on road trip taxi squads, so he could find a rhythm in consistent simulation games there.
In his eight MLB games ahead of Friday, Kirilloff was batting .115.
