Waldron (forearm) struck out four and allowed two earned runs on two hits and four walks across 2.2 innings Thursday in a rehab start with Triple-A El Paso.
Waldron has now made three rehab starts with El Paso and built up to 59 pitches during Thursday's outing. Though the Padres are seemingly letting Waldron get stretched back out as a starter, he may need to show improved results on the farm in order to get a look in the big-league rotation.
