Diamondbacks Make BIG Gamble with Zero Lefties in Their Opening Day Bullpen

The Arizona Diamondbacks are heading into the 2026 season with a bold and potentially disastrous decision: not a single left-handed pitcher in their bullpen. We break down the full relief corps, what went into this all right-handed approach, and why it could seriously backfire against key matchups throughout the season.

We also roll out our full D-backs season predictions, including team MVP, offensive leaders, potential All-Stars, and where we see Arizona landing in the standings by year’s end. Plus, we dive into the questionable 9-9-9 challenges making the rounds across MLB and explain why Presidente delivered the best beer can design we’ve ever seen.
