Excerpt from article: With another three hitless at-bats Saturday, the veteran's average dropped to .105 through seven games with the White Sox. And Guillen's postgame tune changed just a bit. As has been pointed out with closer Bobby Jenks' struggles, these March statistics ultimately mean nothing. Nonetheless, Guillen sees something missing with Teahen. "I'm starting to worry a little bit about Teahen," Guillen said. "I see the same swing. He's not getting anything going for himself. He has to work to try to get better. He's going to get more at-bats. Right now, he's struggling at the plate."
