Drew Rasmussen has taken over the American League lead in WHIP, posting a mark of 0.92 to move ahead of Cam Schlittler as of Friday, September 11, 2026. The Rays right-hander now sits alone atop the AL pitching efficiency leaderboard — and if you've been watching him work this season, it shouldn't surprise you. Rasmussen has been one of the most composed arms in the rotation, doing exactly what a pitcher with a 0.92 WHIP does: keeping traffic off the bases and giving Tampa Bay a chance to win. With Rasmussen and Schlittler deadlocked at identical marks, the margin separating first and second is essentially zero — which means every batter faced from here matters.

Rasmussen's 2026 WHIP in Context

A 0.92 WHIP is genuinely elite — full stop. To lead the entire American League in that category means Rasmussen is allowing fewer than one baserunner per inning on average across his starts this season. That's the kind of number that holds up deep into September, which is exactly where we are now.

There are no flashy win streaks attached to this milestone — just the quiet, relentless competence that Rays fans at Tropicana Field have come to expect from Rasmussen when he's locked in. This is a pitcher who does his damage in the margins, and those margins have added up to an AL-best number.

What to Watch

  • The gap between Rasmussen and Schlittler is razor thin — 0% margin per the latest data, meaning they're tied to three decimal places — so the lead could flip again with a single shaky inning from either pitcher.
  • With the regular season winding toward its conclusion, Rasmussen's next start will carry added weight for his hold on the AL WHIP crown.
  • A 0.92 WHIP at this stage of the season is a strong indicator of a pitcher operating near the top of his game, and Rasmussen has earned his place in that conversation.

This is the kind of leaderboard position that matters both for individual recognition and for what it signals about a pitcher operating near the top of his game. Keep an eye on Rasmussen's next outing — at this margin, nothing is locked in.
