The Rangers' No. 7 prospect homered and drove in six runs, falling a triple shy of the cycle, on Friday as Surprise whipped the Peoria Javelinas, 17-4, for their Arizona Fall League-leading 20th win.
Braves prospect Joey Terdoslavich also went deep and contributed three RBIs as Surprise matched an AFL season high with 21 hits.
Royals top prospect Wil Myers went 5-for-5 with a walk, three runs scored and and two RBIs to raise his average to .384, Rays first-round pick Mikie Mahtook chipped in three hits, including a pair of doubles, and an RBI, while Leury Garcia (Rangers) hit his third Fall League homer and plated three runs.
"The last couple days, I have felt locked in at the plate," said Olt, who extended his hitting streak to nine games and tied Salt River's Nolan Arenado (Rockies) for the league lead with 30 RBIs. "The biggest thing is that I'm not chasing bad pitches. I'm driving the balls I can hit, and that really helps."
Olt got the Saguaros (20-7) on the board early, lacing a two-run double to center field in the first inning off Mets starter Collin McHugh.
"[McHugh] was working me away the whole at-bat," he said. "At 3-1 with a runner in scoring position, I knew he was going to go fastball away to try and nibble at the corner, so I was looking away. I'm always sitting on the fastball and trying to react to anything up in the zone."
Terdoslavich's two-run shot in the third was his third in the AFL and extended the Saguaros' lead to 5-1 before Garcia went deep an inning later.
Garcia and Myers delivered two-run singles in the fifth, the third of six consecutive innings in which Surprise plated at least one run. Olt capped his big afternoon with with a three-run homer in the eighth.
"It was tough to tell whether it was gone," Olt said of his eighth fall homer. "I was trying to get on top of the ball, trusting my hands and reacting when I have to. This is a great experience for me, facing all these good pitchers who can go in and out, up and down.
"We all come to win, and everyone has that mentality. I feel that every time Wil is on base I get the chance to drive him in. He's a special hitter. And Joe is a great hitter from both sides of the plate. He's a tough out."
Rangers left-hander Miguel De Los Santos (4-0) notched his league-leading fourth win after holding the Javelinas to a run on four hits over five innings. He struck out seven, did not walk a batter and threw 74 pitches.
McHugh did not fare nearly as well in his fifth AFL start. The 2008 18th-round Draft pick was charged with five runs on seven hits and a walk over three innings. He struck out six before fellow Mets prospect Robert Carson surrendered three runs over 1 1/3 frames.
Matt Adams (Cardinals), Wilfredo Tovar (Mets) and Jaff Decker (Padres) homered for Peoria (12-15).
