The Padres announced that they designated right-hander Neil Wagner for assignment. The move creates 40-man roster space for Thad Weber, who was claimed off of waivers from the Tigers today. The Padres placed right-hander Jason Marquis on the 15-day disabled list and recalled right-hander Brad Boxberger in related moves.
The Padres claimed Wagner off of waivers from the Athletics at the end May, but haven't promoted him to the MLB level. The 28-year-old has a 5.28 ERA with 8.4 K/9 and 3.3 BB/9 in 58 innings of relief pitching for the Pacific Coast League affiliates of the A's and Padres this year.
