Schrock went 2-for-6 with an RBI and a run scored in a back-and-forth game that saw the Solar Sox take control with seven runs in the last three innings, including a three-run ninth that broke a 7-7 tie and put it away.
"I'm pretty tired now," Schrock said with a laugh. "It was a great day. We swung the bats great. If you've got 16 hits, you're going to win a lot of ballgames. So it was a really fun day. It's fun running around and it's just awesome being out here."
Schrock, 22, was selected in the 13th round of the 2015 Draft by the Washington Nationals after playing at the University of South Carolina. He was traded to the A's in August in the Marc Rzepczynski deal and has continued his progression through the Minor Leagues.
Schrock, who hit .341 at Class A Advanced Potomac in 2016 while with Washington, made it to Double-A Midland in the Oakland organization. Now he's batting .303 with a .798 OPS in the Fall League, but he knows he has to keep improving if he's to crack the big-league roster down the road.
"I need to go out and play good baseball, baseball that I know how to play," Schrock said. "This is probably the best pitching I've seen on a consistent basis. Pitch recognition is big. I need to lay off some pitches I'm swinging at, some off-speed pitches in the dirt.
"I'm going to continue to play the game hard and improve my defense as much as I can."
Defense wasn't the main theme of Thursday's game, however.
That lead held until the second inning, when the Desert Dogs answered with a three-run frame courtesy of an RBI single by second baseman Tim Locastro (Dodgers) and run-scoring groundouts by center fielder Ramon Laureano (Astros' No. 29) and third baseman Drew Ward (Nationals' No. 10 prospect).
The Desert Dogs took a 7-5 lead in the bottom of the seventh inning, but the Solar Sox closed the game out with a fury.
First baseman Juan Kelly (Blue Jays) and left fielder Dexter Kjerstad (Marlins) each hit solo homers in the top of the eighth to tie the game, and Mesa rallied for three runs in the ninth to win it.
Standout hitters for Mesa included center fielder Yefri Perez (Marlins), who went 3-for-5 with two runs, and A's third baseman Yairo Munoz (No. 7), who was 2-for-4 with a run.
