Knehr will start Tuesday against Pittsburgh, Kevin Acee of The San Diego Union-Tribune reports.

EDGE Analysis

Yu Darvish was scratched from his scheduled start due to illness, so Knehr will temporarily fill in as San Diego's starter. The 26-year-old righty has made six major-league starts and holds a 5.24 ERA and 1.40 WHIP through 46.1 innings throughout his MLB career.
