The Seattle Mariners activated veteran infielder Dave Hansen from the 15-day disabled list on Monday. Hansen has been sidelined with tendinitis in his left elbow since July 2. The 36-year-old is batting .194 (6-for-31) in 25 games this year and is a career .262 hitter in 15 major-league seasons with the Dodgers, Cubs, Padres and Mariners. To make room on the active roster, Seattle optioned outfielder Chris Snelling to Triple-A Tacoma. Snelling, 23, appeared in just four games for the Mariners since being recalled in early July and went hitless in five at-bats.
