Jeff Lewis and the Historic .800 Single-Tournament Batting Average

Following our feature on Peter Meredith’s no-hitter records, we flip the page back to offensive excellence to honor one of the most blistering, unconscious weeks at the plate in fastpitch history: Jeff Lewis.

Since making his tournament debut in 2017 with the Kegel Black Knights, Lewis has been a steady, dependable presence in the lineup. But during the 2023 ISC World Tournament, he put on a hitting clinic for the ages, setting the all-time record for the highest batting average in a single ISC World Tournament at .800.

A Pure Display of Hitting Mastery

Hitting .800 over 5 games against world-class pitching isn’t just getting hot—it’s nearly impossible. Lewis stepped into the box 16 times in 2023 and delivered a masterclass in barrel control:

• 12 Hits on 15 At-Bats (.800 Batting Average)
• 2 Home Runs & 10 Singles
• 9 RBIs & 5 Runs Scored
• .813 On-Base Percentage | 1.200 Slugging Percentage | 2.013 OPS

Out of 16 plate appearances, Lewis reached base in 13 of them, failing to record a hit in only three at-bats all week long. His 2.013 OPS stands as one of the most efficient offensive tournaments ever recorded.

A Pillar of the Kegel Black Knights

That 2023 performance wasn’t an isolated stroke of luck—it was the peak of an outstanding ISC career. Across eight tournament appearances from 2017 through 2025 with KBK, Lewis has proven himself to be a big-time producer:

• Career Batting Average: .346 (37 Hits in 107 At-Bats)
• Career Plate Appearances: 117 (35 Games Played)
• Career Power & Clutch: 6 Home Runs, 26 RBIs, 7 Walks, and an .825 career OPS.

When the stakes are highest, Jeff Lewis has shown that no pitch is out of reach, leaving an indelible mark on the ISC record books with his untouchable .800 summer in 2023.
