The Twins will need to make a corresponding move prior to the game. That move could be sending Justin Morneau to the disabled list, depending on the results of his left wrist examination conducted by Dr. Thomas Varecka of the Twin Cities:
If it doesn't look good for Morneau, he'll be place[d] on the DL. And if he check[s] out OK, they'll have to cut another player.
Butera, 28, has 142 games under his belt as a professional between 2010-2011. In 409 plate appearances, Butera has a career .178 / .220 / .261 with four home runs, two triples, and fifteen doubles. He's batting .279 through fifteen games in Rochester this season.
Butera will be the third catcher behind Joe Mauer and Ryan Doumit, and could be insurance since Mauer took a foul tip off the knee on Sunday.
