Last call

• Right-handed reliever Jairo Asencio, who had trouble acquiring a work visa in the Dominican Republic, finally made his Brewers debut on Sunday. He has a big arm but has found trouble in his career, having been suspended in 2010 after an investigation revealed he signed with the Braves under a false name -- Luis Valdez. In January, Asencio was kicked off his Dominican Winter League team for what the club described in a statement as attitude issues.

Asencio made 30 appearances last season for the Indians and Cubs, positing a 3.07 ERA in 12 games with Chicago. In 2011 at Triple-A Gwinnett, a Braves affiliate, he led the league with 26 saves.

• Roenicke has been encouraged by third baseman Aramis Ramirez's at-bats since the veteran returned from a knee injury. Ramirez has asked to play most of the Brewers' remaining exhibition games.

"I just don't mean the results -- the ball is coming off his bat better," Roenicke said. "He's seeing the ball better, he's having better at-bats, and I'm hoping that will continue on into the season."

• The Brewers borrowed a total of 28 players from Minor League camp for Sunday's split-squad games against the Rockies and Padres, including outfielder Rene Tosoni, whom Roenicke mentioned as particularly impressive in his appearances this spring. The team discussed calling over outfielder Victor Roache, one of Milwaukee's first round Draft picks last year, but he has been dealing with a hamstring strain, Roenicke said.
