T.J. Sikkema is a Common 64 OVR Starting Pitcher card for the Free Agents, part of the Live 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, T.J. Sikkema works with a 4-pitch arsenal led by a 91 mph Sinker and a 82 mph Changeup. His pitching ratings include 73 Velocity, 57 Control, and 76 Break. The profile favors a movement-heavy arsenal built to miss bats.

DiamondOps grades each pitch in T.J. Sikkema's arsenal: Slider (S), Sinker (S), 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 Sinker off the Slider, so the two share a release look. Velocity works against the card here — its 73 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, T.J. Sikkema currently buys for about 7 stubs, with sell orders near 0 stubs. Over the past 7 days the price has held roughly steady. Its quick-sell value of 5 stubs sits at or above the sell price, making it quick-sell viable. DiamondOps suggests waiting for a better entry point.

OpScore is DiamondOps' composite rating of a card's in-game performance value. T.J. Sikkema earns an OpScore of 50.5 on Legend difficulty, ranking #2686 among all cards and #548 among Starting Pitchers.
