Clevinger (triceps) was activated from the injured list ahead of his start Sunday against the Brewers, Kevin Acee of The San Diego Union-Tribune reports.
His most recent big-league start (May 17) was his best start of the season, as he struck out five over five scoreless innings of one-hit ball in Philadelphia. Clevinger's triceps strain didn't sideline him long enough for him to need a rehab start.
