The 2nd Inning Cornerstone Evolutions in MLB The Show 25 introduce three dynamic options that can evolve from 80 overall starting points into serious Diamond Dynasty threats. Whether you're chasing XP or squad-building versatility, this trio of legends has something for every playstyle. Let's break them down.
CP Cornerstone Bruce Sutter (Chicago Cubs)
Bruce Sutter kicks off as the go-to relief option in this program. Known for his devastating splitter, Sutter is a dream for players who thrive on mixing speeds and generating whiffs. As he levels up through the Evolution path, you'll end up with an elite finesse reliever. Sounds counterintuitive and for many it is. But those not afraid to put their tunnel and gameplan skills to use will find themselves with a disgusting relief option.

True Overall: 87.58 - #5 CP
Meta Overall: 71.28 - #19 CP
LF Cornerstone J.D. Martinez (Boston Red Sox)
JD Martinez is a pure hitter from the jump. Starting at 80 overall, his Evolution path amplifies his contact, power, and clutch ratings, making him one of the best early Designated Hitter options in Diamond Dynasty. While his defense isn't elite, you won’t care—he’s built to mash.

True Overall: 87.77 - #12 LF
Meta Overall: 86.36 - #6 LF
1B Cornerstone Tony Clark (Detroit Tigers)
Tony Clark enters as the spicy sleeper pick. A switch-hitting first baseman with passable 1B defense, he brings lineup balance and power from both sides of the plate. As he evolves, his pop and plate discipline make him a sneaky power boost for any lineup.

True Overall: 86.94 - #20 1B
Meta Overall: 88.44 - #9 1B
