Red Sox send Melancon to Triple-A, promote Tazawa
Melancon (0-2), acquired from Houston during the offseason and expected to be Boston's primary setup man, gave up 11 runs in two innings over four appearances. He faced six batters in Tuesday's 18-3 loss to Texas, allowing six runs and four hits, including three homers, while walking two.
Tazawa was promoted on Wednesday. He made four scoreless appearances with Pawtucket this year. He's 2-3 in his career with a 7.31 ERA in nine games with the Red Sox.
