The move was apparetly made by Brewers' manager Ron Roenicke because Calgary native Jim Henderson (the Brewers' closer last season) was struggling with his velocity.
So far, Roenicke needs to be highly praised for making the move. Rodriguez has an earned run average of 0.00 in three innings pitched, and has only given up one hit with six strikeouts, zero walks and two saves.
What Rodriguez also brings to the Brewers is a wealth of experience in high pressure situations. He was instrumental in the reliever position as the Anaheim Angels won the 2002 World Series. In 18 2/3 innings pitched, Rodriguez had a sparkling earned run average of 1.93 with 28 strikeouts compared to only five walks.
Since then, Rodriguez has had 306 career saves with the Angels, New York Mets and Milwaukee Brewers.
