Richards pitched eight strong innings and, with MLB.com's No. 1 prospect Mike Trout going yard, Arkansas topped Frisco, 4-3, in Monday's 15-inning affair.
Richards, who the Angels selected 17 spots behind Trout with the 42nd overall selection in the 2009 Draft, allowed two runs on 10 hits in his second-longest career outing. Last May, he threw nine innings of one-run ball for Class A Cedar Rapids.
Long after Richards left Monday, Frisco grabbed a temporary 3-2 lead in the top of the 13th inning. But Trout, who went 3-for-6 with a double, retied the score when he homered off of Frisco's sixth pitcher of the game, Justin Miller (0-1). It was Trout's fourth longball of the season. His batting average through 11 games sits at .318.
Trout also had a hand in Arkansas' winning rally two innings later. After Adam Younger smacked a leadoff double, the highly touted outfielder bunted him to third base, and Younger scored three batters later on Luis Jimenez's walk-off single into left field.
