   CLEVELAND: Now that Lonnie Chisenhall has been called up because of an injury to Jack Hannahan, how much will he play?

   ""We're going to find at-bats for Lonnie,'' manager Manny Acta said. ""Right now the way our lineup is, he can make some contributions. He'll play third and some DH, too.'' 

   CHICAGO: The Indians will play the White Sox this afternoon with a diminished lineup after catcher Carlos Santana and shortstop Asdrubal Cabrera were scratched because of injuries sustained Friday night.

   The Tribe already was missing designated hitter Travis Hafner, who suffered a knee injury Wednesday and did not play Thursday or Friday.

Being a little brash and not afraid to speak one’s mind are perfect qualities for a major league baseball closer.

However, Indians closer Chris Perez not only unleashed those qualities on the Miami Marlins Saturday, but also then directed his frustration toward the team’s struggling fan base following his dominating performance in Saturday’s 2-0 victory.

Indians closer Chris Perez was mad.

So mad, he struck out the Marlins side in the ninth inning Saturday- leaving all three batters staring at called third strikes - all with just 10 pitches.

Indians general manager Chris Antonetti met with reporters for 12 and a half minutes Saturday afternoon before the game, touching on a variety of topics.

Here’s the question and answers from the brief session:

Derek Lowe pitched his first shutout in nearly seven years, throwing a six-hitter this afternoon and leading the Indians over the Minnesota Twins 5-0.

Shin-Soo Choo scored after a leadoff double in the third inning, then hit the first of three Indians home runs in the fifth against Jason Marquis (2-3). Asdrubal Cabrera and Carlos Santana also homered to break the game open.

   BOSTON: Josh Tomlin was scratched from tonight's start agsinst the Red Sox with soreness in his right wrist and placed on the 15-day disabled list.

  No detailed diagnosis or explanation of how the injury was sustained is yet available, but Zach McAllister was called up from Columbus to take Tomlin's start and presumably whatever starts he will miss while he's on the DL .

   BOSTON: VInnie Pestano became a record-breaking pitcher for the Indiians Thursday night.

   With BaseballReference.com's help, research shows that Pestano is the first Tribe pitcher since 1918 to strike out at least one batter in his first 16 appearances of the season.
