Sean Murphy upped his season home run total to seven on Sunday with his second two-homer of the season. The Athletics' No. 14 prospect went deep in each of his first two at-bats of Class A Advanced Stockton's 3-2 win over Lake Elsinore. Murphy, the A's third-round pick from the 2016 Draft, has caught fire over the past two games, going a combined 5-for-8 with three homers and four RBIs.
