Matthews (1-1) took the loss against San Diego on Monday, allowing five runs (two earned) on four hits and two walks while striking out one batter over five innings.
Matthews was given a one-run lead in the top of the first inning, but he allowed the Padres to score twice in the bottom of the frame. The rookie hurler allowed three more runs in the third -- those were all unearned, though the error that led to them was committed by Matthews himself. The right-hander added to the miscue with a pair of walks in the inning, which was very uncharacteristic for him given his minuscule 0.6 BB/9 over 97 frames in the minors this season. Matthews' command has been consistently outstanding throughout his time as a pro, so that aspect of his pitching will likely carry over to the majors. However, he made only four appearances at the Triple-A level (and registered a 5.68 ERA over 19 innings) prior to his call-up to the majors, so fantasy managers would probably be wise to tempter expectations as he adjusts to facing big-league hitters.
