Presley, 28, came to Minnesota last year in the Justin Morneau trade. Over parts of four years of MLB action, he has a .264/.304/.411 line in 821 trips to the plate. Presley has also hit 17 long balls and swiped 20 bags, though the latter figure comes against 15 times in which he's been caught stealing.
Meanwhile, the 36-year-old Valdes was claimed off of waivers in October from the Phillies. Though his 7.46 ERA in 35 innings last year with Philadelphia is unsightly, his 9.5 K/9 and 2.1 BB/9 (to say nothing of a 3.10 SIERA) make things look much better. Indeed, he posted a 2.90 ERA (10.2 K/9, 1.5 BB/9, 0.742 WHIP) in 2012 with the Phils, and had put up similar figures this spring (one earned, one walked, and six struck out in 5 1/3).
