Ryan Sloan is a Red Diamond 99 OVR Starting Pitcher card for the Mariners, part of the Pipeline set in MLB The Show's Diamond Dynasty. He throws right-handed. The card was added to Diamond Dynasty in August 2026.

On the mound, Ryan Sloan works with a 5-pitch arsenal led by a 98 mph 4-Seam Fastball and a 95 mph Sinker. His pitching ratings include 99 Velocity, 99 Control, and 98 Break. The profile favors a balanced mix of command and movement. Notable quirks include Break Outlier from a total of 3 quirks.

DiamondOps grades each pitch in Ryan Sloan's arsenal: 4-Seam Fastball (S), Sweeper (S), Cutter (S), Sinker (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. Its 99 mph Sinker adds a velocity bonus on top. 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, Ryan Sloan currently buys for about 38,880 stubs, with sell orders near 28,800 stubs. Over the past 7 days the buy price has fallen roughly 18%. Flipping at current buy and sell prices nets roughly 6,190 stubs, about a 21% return. DiamondOps suggests waiting for a better entry point.
