Kubel entered the game just 1-for-14 in Grapefruit League play, but feels like his swing is starting to come around.
"It felt good to finally hit one hard," Kubel said. "The results aren't there, but I feel like over the last few games, my last four or five at-bats are feeling pretty good. So if it keeps getting better each day before the season starts, I'll be right where I want to be."
Kubel still has a strong shot to make the club as a designated hitter/outfielder, but he has to prove he can contribute offensively after an injury-plagued season last year in which he hit just .216 with five homers and 32 RBIs in 97 games with the D-backs and Indians.
Twins manager Ron Gardenhire is familiar with Kubel, who played with the Twins from 2004-11, and was pleased to see him snap his recent funk with a homer.
"He can click on a baseball -- we know that," Gardenhire said. "It's just a matter of time. We'll see more at-bats and we'll go from there."
