Following most every home run by Mike Olt is a victory by the Surprise Saguaros, although the shock around the Arizona Fall League has undoubtedly worn off.

The Rangers' No. 7 prospect slugged his league-leading 12th homer Saturday afternoon to power the Saguaros to a 6-4, seven-inning victory over the Scottsdale Scorpions.

Surprise (23-9), which clinched the West Division title and a spot in the Championship Game on Wednesday, must win three of its final four games to achieve the highest winning percentage in AFL history. The Mesa Solar Sox (.705) went 31-13 in 1999.

The Saguaros improved to 6-2 in games in which Olt has cleared the outfield fence.

Olt smacked a solo shot, his third in five at-bats after Friday's two-homer, five-RBI game, off starter Aaron Fleet (Giants) in the second inning. The 2010 first-round pick also leads the AFL with 39 RBIs in 23 games, including 17 in his last seven contests.

Christian Colon, the Royals' No. 4 prospect, delivered a two-run double in the fifth to put the Saguaros ahead for good, 4-3. Leonys Martin capped the four-run outburst with a two-run single. Texas' No. 10 prospect went 3-for-3 to raise his average to .286.

Red Sox outfielder Alex Hassan also was 3-for-3 for Scottsdale but was left on deck as the game ended and fell a triple shy of the cycle. He turned on a 2-0 offering from Marlins right-hander Alex Sanabia in the first and launched a three-run homer. Hassan also collected an assist, catching Martin trying to stretch a single into a double to end the Saguaros' rally in the fifth.

Fleet gave up two runs on three hits over two innings, while Sanabia allowed three runs on three hits over four frames.

Bryce Harper, MLB.com's No. 2 overall prospect, went 0-for-3 as his 16-game hitting streak was snapped.
