Leon Day is a Diamond 89 OVR Starting Pitcher card for the Free Agents, part of the The Negro Leagues set in MLB The Show's Diamond Dynasty. He throws right-handed. As a two-way card, he can be used as both a hitter and a pitcher in the same lineup. He is also eligible at Second Baseman and Center Fielder. The card was added to Diamond Dynasty in April 2026.

On the mound, Leon Day works with a 5-pitch arsenal led by a 96 mph 4-Seam Fastball and a 94 mph Sinker. His pitching ratings include 90 Velocity, 64 Control, and 92 Break. The profile favors a movement-heavy arsenal built to miss bats. Notable quirks include Dead Red, Stopper, and Situational Hitter from a total of 6 quirks.

Leon Day is eligible at 3 positions, and DiamondOps scores each one separately: Second Baseman (81.9), Center Fielder (79.8), and Designated Hitter (79.5) on All-Star. Which slot is best depends on how you play — Second Baseman on All-Star, Designated Hitter on Hall of Fame, and Designated Hitter on Legend. At Second Baseman the card scores 81.9 on All-Star, 86.5 on Hall of Fame, and 87.6 on Legend — it keeps 107% of its All-Star value at the top difficulty, which is unusually durable. Among Starting Pitchers the card ranks #98 on Legend and #190 on All-Star.

DiamondOps grades each pitch in Leon Day's arsenal: 4-Seam Fastball (S), Sinker (S), Curveball (B), Changeup (B), and Slurve (B). 2 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.

On the Diamond Dynasty market, Leon Day currently buys for about 3,974 stubs, with sell orders near 3,500 stubs. Over the past 7 days the price has held roughly steady. Flipping at current buy and sell prices nets roughly 74 stubs, about a 2% return. DiamondOps suggests waiting for a better entry point.

OpScore is DiamondOps' composite rating of a card's in-game performance value. Leon Day earns an OpScore of 89.2 on Legend difficulty, ranking #547 among all cards and #98 among Starting Pitchers.
