Keith Foulke is a Red Diamond 99 OVR Closer card for the Red Sox, part of the Finest set in MLB The Show's Diamond Dynasty. He throws right-handed. The card was added to Diamond Dynasty in July 2026.

On the mound, Keith Foulke works with a 5-pitch arsenal led by a 94 mph 4-Seam Fastball and a 94 mph Sinker. His pitching ratings include 90 Velocity, 92 Control, and 99 Break. The profile favors a balanced mix of command and movement. Notable quirks include Stopper from a total of 3 quirks.

DiamondOps grades each pitch in Keith Foulke's arsenal: Slider (S), 4-Seam Fastball (S), Sinker (S), Cutter (S), and Circle Change (A). 4 of them grade S-tier, which is what separates a genuine out-pitch mix from a deep-but-flat arsenal. Its strongest tunnel pairing is the 4-Seam Fastball off the Sinker, so the two share a release look. Velocity works against the card here — its 90 mph Sinker is slow enough to cost it in the arsenal score. Arsenal grades are the same at every difficulty — unlike a hitter's OpScore, a pitch mix does not re-weight as you climb.
