The San Diego Padres recalled right-hander Reiss Knehr from Triple-A El Paso on Sunday and optioned right-handed knuckleballer Matt Waldron one day after he made his major league debut.
Knehr, 26, returns to the Padres after posting a 12.27 ERA in three relief outings earlier this season. He is 1-2 with a 5.24 ERA in 20 career outings (six starts) with the Padres over the past three seasons.
Waldron, 26, gave up two runs on four hits over 4â…” innings of his MLB debut Saturday against the Washington Nationals in a game San Diego lost 2-0.
Waldron was making a spot start for Michael Wacha, who was given additional rest to deal with shoulder fatigue.
