Yamamoto will start Sunday in Game 2 of the NLDS against San Diego, Jeff Sanders of The San Diego Union-Tribune reports.
Yamamoto allowed eight earned runs over six innings across his two appearances against the Padres during the regular season, though it's been nearly six months since he last faced the division rival. More recently, the 26-year-old righty turned in a 3.38 ERA and 21:5 K:BB over 16 frames following his return from the injured list Sept. 10.
