Griffin posted a .894 OPS this spring with 3 home runs in a limited sample against major league pitching. His 2025 minor league line, .333/.415/.527 with 21 home runs and 65 stolen bases across 3 levels, showed zero dropoff as competition improved. That last part matters more than anything else. Prospect performance that holds up through level jumps is signal; prospect performance that declines is noise asking you to wait. Griffin's signal is loud.
The Pirates should start him on Opening Day against the Mets. Not in late April. Not after some artificial seasoning period in Triple-A. Day 1.
The Alternatives Are Not Alternatives
Pittsburgh's internal competition at shortstop includes Nick Gonzales, Jared Triolo, Alika Williams, and Yordany De Los Santos. Gonzales has upside as a utilityman. Triolo can hold a position. Neither one changes the competitive math for a team chasing an NL wild card for the first time since 2015. The Pirates spent this offseason acquiring Brandon Lowe, Ryan O'Hearn, and Marcell Ozuna precisely because they believe 2026 is worth trying to win. Starting Gonzales at short while Griffin rides the bus to Indianapolis contradicts every dollar they just spent.
The counterargument worth taking seriously: Griffin is 20 years old, has roughly 1 month of Double-A experience, and the Pirates are a small-market team that cannot afford to burn control years carelessly. Paul Skenes debuted May 11, 2024, avoided a full service year, and still won Rookie of the Year. The template exists. The Pirates could delay Griffin past April 10 and save a year of arbitration eligibility without costing him ROY hardware. That is a real consideration, and anyone who dismisses it is not reading the CBA carefully enough.
But here is where the service-time math actually flips: if Griffin debuts after April 10, finishes second or better in NL ROY voting, and the Pirates miss the wild card by 2 games, they sacrificed real wins for a financial hedge that did not fully pay off. The 2024 Skenes situation worked because Pittsburgh was not a serious contender. The 2026 Pirates, with Lowe and Ozuna in the lineup, are at least trying to be one. That changes the win probability calculus on every delayed-debut scenario.
What .894 OPS Against MLB Pitching Actually Tells You
Spring training OPS is a flimsy stat. I know this. Sample sizes are tiny, pitchers are working on specific sequences rather than attacking hitters, and the whole environment is closer to a controlled experiment than a real game. Griffin's .208 average with no walks is genuinely worrying as a signal about pitch recognition. I am not going to pretend .894 OPS in March is the same as .894 OPS in September.
What I will say is this: the underlying 2025 data is not a spring sample. It is a full season across 3 competitive levels with an elite speed and power combination that almost nobody in the minors produced. When a 19-year-old does that, you are not waiting for more proof. You are stalling.
The Pirates lead camp in shortstop plate appearances going to Griffin, which means they already know what the answer is. Now they need to say it out loud. Start him April 2 at Citi Field, let Freddy Peralta be his first real test, and trust the process that produced the best prospect line in baseball last year.
Pittsburgh has not made the playoffs since 2015. Holding back the best player in camp will not fix that. Starting him might not either. But only one of those decisions is consistent with the offseason they actually had.
