Yamamoto is starting Game 1 of the NLDS against San Diego on Saturday, Bill Plunkett of The Orange County Register reports.
Yamamoto was originally slated to start Game 2, but he'll flip spots with Jack Flaherty. If the series goes a full five games, Yamamoto is projected to pitch in the decisive contest. He's pitched well in his return from a triceps injury, allowing two or fewer earned runs in three of four starts.
