Why he matters right now
Foster Griffin is top-10 in the majors in wins
He is 3rd in wins at 15 — 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 23 straight days.
The case in 30 seconds
- 15 3rd in wins at 15 on MLB's season leaderboards MLB season leaderboard (the league's own top-10 board of qualified players, not this site's roster)
- 3.26 ERA over 160 innings, with 142 strikeouts, 28 starts and a 1.14 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 160 innings over 28 starts; the same rate to the end of the season means roughly 183. Velocity and innings both have to hold, and neither is guaranteed — this page reports what the measurements say, not what a medical staff knows.
