Melancon blew a save and took the loss in Sunday's 6-5 loss to the Diamondbacks, allowing two runs on four hits while striking out one and recording just two outs.
Melancon entered with a one-run lead and retired the first two batters he faced, but he proceeded to allow the next four men to reach base as Arizona plated a pair for a walkoff win. Big things were expected from the veteran after he was acquired during the offseason, and despite this inauspicious start to his run with the Giants, he should bounce back in no time.
