Corner infielders

Mark Teahen, 3B/OF, Chicago White Sox

Mark is ready to Teahen off

The ChiSox activated Teahen (finger) from the disabled list today. He's hitting .255 with three homers and 14 RBIs in 137 at-bats this year. The South Siders optioned Dayan Viciedo to Triple-A Charlotte. However, manager Ozzie Guillen said that Teahen won't play at the hot corner every day.

Teahen's minimal offense and Omar Vizquel's relative resurgence are two glaring reasons for that decision. As a left-handed hitter, Teahen could still find himself in the lineup somewhat regularly. He was 12-for-33, with 10 walks, on his rehab assignment.
