Joe Nathan picked up his 12th save and struck out a batter in a scoreless ninth inning as the Tigers defeated the A's on Tuesday. The 39-year-old right-hander hasn't allowed a run in 12 of his last 13 appearances, which has allowed him to chisel his ERA down to 3.66 after a rocky start to the year. Nathan ranks third in the American League in saves and has a lower WHIP (1.07) than Greg Holland, Jonathan Papelbon and Kenley Jansen.
