Today, we're diving into matchups where the models are popping up some interesting predictions. Let's break down the key players and pitchers for these first at-bat scenarios.

🤖 2026 Tech Watch: The ABS Impact

One reason we’re feeling even more confident in our "Fair Odds" this season is the MLB ABS Challenge System.

In years past, a brilliant 0-0 paint job could be called a ball simply due to human error—effectively 'burning' a perfectly good bet. In 2026, the MLB ABS Challenge System is cleaning up that 'dirty data.' With an overturn rate over 60%, we’re finally seeing a market where blatant misses are corrected in real-time. This technology rewards accurate arms like Mick Abel (87.5% zone accuracy today) and disciplined hitters who can force a challenge, which is exactly where our model finds its edge.
