The Pirates have claimed left-hander Sam Moll off waivers from the Athletics, according to press release. Pittsburgh’s 40-man roster is now at 39 players.

Moll, 25, is a former third-round pick of the Rockies that was traded to Oakland this past August for cash considerations. The A’s designated him for assignment last week when clearing space on their 40-man roster to protect several players from the Rule 5 Draft.

The 2017 season saw Moll make his big league debut in Oakland, though the results weren’t especially pretty. In 6 2/3 frames, the Memphis product was tagged for eight runs on 13 hits (including two homers) and three walks with seven strikeouts.

In 54 1/3 innings between the Triple-A affiliates for the Rockies and the A’s, Moll pitched to a more respectable 3.64 ERA with 7.8 K/9 against 3.1 BB/9. He also registered a promising 50.3 percent ground-ball rate in his 47 1/3 innings with Colorado’s Triple-A affiliate.

He joins Nik Turley as the second southpaw claimed off waivers by the Bucs since the offseason began.
