The Pittsburgh Pirates announced on Monday afternoon that they have claimed left-handed pitcher Sam Moll off of waivers from the Oakland A's.
The 25-year-old Moll made his Major League debut this September with the A's, posting a 10.80 ERA and a 2.40 WHIP over 6.2 innings and 11 appearances. He spent the rest of the 2017 season in Triple-A, split between the A's and the Rockies, where he posted a 3.64 ERA and 1.47 WHIP, with 47 strikeouts in 54.1 innings over 50 appearances. Moll has two options remaining.
Baseball America rated him among the top 30 prospects for the Rockies four times since he was a third round draft pick in 2013.
