South Pasadena athletic director Ralph Punaro confirmed Tigers baseball coach Rob Hertel has resigned. Hertel was at the helm for two seasons, and at season’s end will complete his third year. He was a walk-on coach. “(Hertel) resigned a couple of days ago,” Punaro said. “He’s still coaching and will coach until the end of the season. We’re sorry that it’s happening. Is it a surprise? Somewhat? He made it public to the players last week.” More details to come.
