Mike Yastrzemski opened his Royals chapter with a jolt, blasting three leadoff homers in 15 games—an MLB milestone that only Rickey Henderson has surpassed for a new team in fewer games. The quick trio puts Yaz in elite company and fuels KC’s late-season pulse, even as his overall batting average sits at .222. Four homers, four doubles and eight walks have yielded a .905 OPS, underscoring value from the top of the lineup as Kansas City eyes a push for meaningful contention.

The Kansas City move, after a Giants swap, hasn’t been spotless—yet the leadoff power and plate discipline keep Yaz squarely on fantasy radar. If he continues to start games with homers, the Royals’ offenses and run production will hinge on his continued atop-order impact. His three-leadoff bombs in 15 games highlight a rare spark that fantasy managers will monitor closely as the season unfolds, especially in formats valuing OBP and plate appearances.
