Vargas picked up three hits and three RBIs on Sunday, and became the first Twins rookie to have at least five multi-RBI games through his first 15 games.
"We love watching him come up to the plate," Twins manager Ron Gardenhire said. "He's a strong kid. He's put together some good at-bats with runners in scoring position. He's even shooting the ball the other way. Whatever it takes. So it's a learning process every day for him, but fortunately for us, he's a big strong kid who doesn't let it get to him."
Vargas has had some issues with strikeouts, but the switch-hitter is working on his plate discipline. He said the return of Joe Mauer has been a big help, as he's been learning from the six-time All-Star.
"They ask me to be more patient at the plate," Vargas said. "I see what they throw to Mauer and that's helped me a lot."
Vargas said the key is to have a plan at the plate, and so far it's working out for the 24-year-old rookie.
"I try just to do the same approach -- look for my pitch," Vargas said. "When I see the pitch that I'm looking for, I try to make contact."
