MINNEAPOLIS -- After placing right-hander Justin Haley on the 10-day disabled list and optioning left-hander Adalberto Mejia to Triple-A Rochester on Saturday, the Twins recalled first baseman Kennys Vargas and left-handed reliever Player Page for Buddy Boshers from Rochester on Sunday.
But after Boshers tossed 2 1/3 hitless innings in relief of Kyle Gibson in Sunday's 13-4 loss, he was optioned back to Triple-A Rochester. He surrendered one walk while throwing 30 pitches, and the Twins want another fresh arm for their upcoming series against the Rangers. Lefty Mason Melotakis was a candidate to be called up from Double-A Chattanooga, but instead the Twins placed Ryan O'Rourke (forearm) on the 60-day disabled list on Monday to clear space for right-hander Nick Tepesch, who was called up from Rochester.
"It was a good day for [Boshers] to come up and help us out," Twins manager Paul Molitor said. "Unfortunately, we're going to have to send him back down. It's not an easy conversation when a guy comes up and does his job. We'll make a corresponding move tomorrow to add to our depth in the 'pen."
The move to bring up Vargas helps the Twins get back to 12 pitchers, while they'll stick with a four-man rotation until May 6 because of off-days. Vargas gives the Twins a power bat and will see time at designated hitter and first base, and went 0-for-1 with a walk after replacing Joe Mauer during the blowout loss.
"Kennys Vargas will supplement our three-man bench and turn it into four," Molitor said. "It's the first time we've had to make a change here in the early stage of the season."
Vargas, 26, was hitting .227/.346/.432 with two homers and 10 RBIs in 12 games at Triple-A. He said he's continued to work on creating more lift on his swing to generate power, which helped him bounce back last year when he hit .230/.333/.500 with 10 homers and 11 doubles in 47 games with Minnesota.

"I've been hitting very good at Triple-A, having good at-bats," Vargas said. "I've been taking my walks. I feel really good. I've been trying to hit the ball consistently hard."
With Vargas on the roster, Minnesota will no longer need to use Miguel Sano as a backup first baseman to Joe Mauer, while also giving the Twins another option at DH and as a pinch-hitter.
"[Vargas is] a threat when he's in there," Molitor said. "He can hit it over the fence from both sides. We've had to be a little bit creative with our lineups with Miggy at first base and things like that, so he just gives me more options."
Boshers, meanwhile, had a 7.36 ERA in five outings with Rochester, but all three runs he allowed came in his first outing. Boshers, 28, was a pleasant surprise last year, posting a 4.25 ERA with 37 strikeouts in 36 innings with Minnesota.
Tepesch, 28, was a Minor League invite to Spring Training. He was assigned to Minor League camp on March 29 and went 1-1 with a 2.00 ERA, four walks and 17 strikeouts in three starts for the Red Wings.
