Ring was not a member of the 40-man roster, so the Yankees designated outfielder Chad Huffman for assignment.
Ring, 29, is a former first-round draft pick out of the 2002 draft. He last pitched in the big leagues for the Atlanta Braves in 2008. He has spent this entire season in the minor leagues with Triple-A Scranton. There he has done well, going 2-1 with a 1.93 ERA over 42 innings and 52 games.
The Yankees called him up mostly because Boone Logan has been the lone lefty in the pen and they don’t want to burn him out before the playoffs.
Huffman, 25, is an outfielder who the Yankees claimed off the Padres' roster at the beginning of the year. He hit .274 with a .763 OPS and 10 home runs in 104 games with Triple-A Scranton. The rest of the league has 10 days to claim him, or the Yankees can keep him.
