Guzman, a switch-hitter, is just 3-for-33 with the Rangers since being acquired from the Washington Nationals on July 30. Manager Ron Washington said he expects Guzman to start on Saturday against left-hander Jon Lester.
"I'm quite sure it's an adjustment," Washington said. "There is a difference in the National League style of attack and the American League. He's seeing pitchers he doesn't know. It could be a lot of things. He might be pressing."
Washington admitted there might be an opportunity for Blanco to start getting more playing time at second base if he shows the manager something. But Washington still likes Guzman, who is a two-time All-Star and was once a premier front-line shortstop for the Twins and Nationals.
"Believe me, Guzman can offer more than what you've seen," Washington said. "Guzman can play. Ya'll haven't seen it yet, but Guzman can play."
