On the league boards

Why he matters right now

Keider Montero is top-10 in the majors in WHIP

He is 6th in WHIP at 1.03 — 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 7 straight days.

The case in 30 seconds

  • 1.03 6th in WHIP at 1.03 on MLB's season leaderboards MLB season leaderboard (the league's own top-10 board of qualified players, not this site's roster)
  • 3.55 ERA over 147 innings, with 98 strikeouts, 24 starts and a 1.03 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

A top-ten finish is a position on a board, not a verdict on a player. The men just below him on it are not meaningfully worse, and one good week moves several places.
