Derek Fisher, a former Gatorade State Player of the Year in Pennsylvania, had a historic night in his debut with Houston Astros affiliate Lancaster of the high-Class A California League.

Fisher, a graduate of Cedar Crest High in Lebanon, Pa., drove in 12 runs to break a 61-year-old league record in a 16-4 victory. Fisher ad three home runs in the first four innings– including a pair of grand slams — and added a three-run double in the seventh. The previous record was held by Stockton’s Robert Rivich with 11 RBI in a 1954 game.

“It’s pretty surreal,” Fisher told MiLB.com. “It’s something that I never would’ve even dreamed of, to be honest with you. I obviously couldn’t have done it without getting up to the dish with the bases loaded twice in three innings.”

Fisher, an outfielder ranked as the 11th-best player in the Astros system by milb.com, was promoted from Class A Quad Cities (Iowa). In 39 games, he hit .305 with six home runs and 24 RBI.

The accomplishment was not lost on Astros GM Jeff Luhnow.

He was the 37th overall pick in the 2014 draft out of the University of Virginia. He opted for college rather than jumping from high schools to the pros after he was drafted in the sixth round of the 2011 draft by the Texas Rangers. He was considered among the top 10 high school prospects in the draft that year after hitting .484 as a senior but signability was a factor, given his commitment to Virginia.
