Graveman (2-2) surrendered six runs on five hits and four walks while striking out three over 3.1 innings in Wednesday's 7-4 loss to the Twins.
He needed 94 pitches (52 strikes) to record just 10 outs in what was his shortest outing of the season, and Graveman saw his ERA rise to 3.95 as a result. He'll try to find his April form in his next start Tuesday at home against the Angels.
