Why he matters right now

Keider Montero is top-10 in the majors in WHIP

He is 5th in WHIP at 0.99 — placements on MLB's own season boards, which rank every QUALIFIED pitcher in the sport rather than the few dozen this site tracks. Qualified is MLB's own bar, and it is the reason a part-season player with a big number is not on these boards at all.

This has been his headline for 14 straight days.

The case in 30 seconds

  • 0.99 5th in WHIP at 0.99 on MLB's season leaderboards MLB season leaderboard (the league's own top-10 board of qualified players, not this site's roster)
  • 3.24 ERA over 139 innings, with 92 strikeouts, 22 starts and a 0.99 WHIP snapshot pitching board — the union of MLB's top-10 pitching boards, then MLB's 1.0 IP per team game rule applied; not the league's full qualified pool

The honest caveat

The open question is workload. He is at 139 innings over 22 starts; the same rate to the end of the season means roughly 162. Velocity and innings both have to hold, and neither is guaranteed — this page reports what the measurements say, not what a medical staff knows.
