JoJo Romero is a Diamond 93 OVR Relief Pitcher card for the Cardinals, part of the Spotlight set in MLB The Show's Diamond Dynasty. He throws left-handed. The card was added to Diamond Dynasty in June 2026.

On the mound, JoJo Romero works with a 5-pitch arsenal led by a 95 mph Sinker and a 95 mph 4-Seam Fastball. His pitching ratings include 96 Velocity, 75 Control, and 99 Break. The profile favors a movement-heavy arsenal built to miss bats. Notable quirks include Stopper from a total of 3 quirks.

DiamondOps grades each pitch in JoJo Romero's arsenal: Sinker (S), Sweeper (S), 4-Seam Fastball (S), Circle Change (A), and Slurve (B). 3 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 Sinker off the 4-Seam Fastball, so the two share a release look. Its 96 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, JoJo Romero currently buys for about 9,859 stubs, with sell orders near 7,400 stubs. Over the past 7 days the buy price has climbed roughly 7%. Flipping at current buy and sell prices nets roughly 1,471 stubs, about a 20% return. DiamondOps suggests waiting for a better entry point.
