White Sox

News: Johnson, whose dramatic home run on the final night of the regular season helped Tampa Bay reach last year's playoffs, has agreed to a minor league contract with the Chicago White Sox. Johnson hit a tying, two-out, two-strike homer off Cory Wade in the ninth inning of regular-season finale against the Yankees, and Evan Longoria's 12th-inning homer won the game and the AL wild-card berth.
Impact: Johnson is a .235 hitter with 53 homers and 188 RBIs in six major league seasons with Oakland and the Rays. He batted .119 with two homers for the Rays last year and was the International League MVP in 2010. In 2005 he batted .275 with 15 homers for the Athletics, who drafted him in 2001.

News: The White Sox have signed Johnson to a minor league contract, the Chicago Tribune reports.
Impact: At age 32, Johnson batted just .119 with two home runs in 91 at-bats last season. Though Johnson has yet to make a much of a splash in the majors, he could bring decent power to the White Sox's lineup if he is moved up at some point in the event of an injury to Paul Konerko or Adam Dunn.
