On the mound, Justin Martinez works with a 4-pitch arsenal led by a 99 mph 4-Seam Fastball and a 95 mph Sinker. His pitching ratings include 99 Velocity, 72 Control, and 76 Break. The profile favors a balanced mix of command and movement. Notable quirks include Outlier I.

DiamondOps grades each pitch in Justin Martinez's arsenal: Slider (S), Sinker (S), 4-Seam Fastball (S), and Splitter (A). 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 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, Justin Martinez currently buys for about 27 stubs, with sell orders near 0 stubs. Over the past 7 days the price has held roughly steady. Its quick-sell value of 25 stubs sits at or above the sell price, making it quick-sell viable. DiamondOps suggests waiting for a better entry point.
