Astros prospect Derek Fisher more than made his mark on Saturday in a record-breaking California League debut.
Fisher, ranked as the club's No. 11 prospect by MLB.com, racked up a California League-record 12 RBIs for Class A Advanced Lancaster, courtesy of three home runs, including a pair of grand slams.
Fisher, the 37th overall pick in last year's Draft, began his night by clubbing a solo homer in the first inning then followed with a grand slam in the second. As if that wasn't enough, Fisher connected for yet another grand slam just one inning later, giving him three homers in as many at-bats.
