Nobody said betting underdogs was comfortable. But comfortable doesn’t always mean profitable — and that’s exactly the conversation we need to have about the Arizona Diamondbacks at +173 against the Atlanta Braves.
Let’s be honest: Atlanta is a strong club, and the market respects them. That’s precisely why the Braves are favored here and why Arizona is sitting on the other side of the ledger with a number that makes your eyebrows go up. At +173, a $100 bet returns $173 in profit if the D-backs pull it off. That’s not nothing.
Now, before you go all-in, let’s keep this real. Upsets happen in baseball more than in any other major sport. The 162-game grind means that even the best teams in baseball lose to the worst ones — repeatedly, throughout a season. That’s just the nature of the game. No lead is safe, no favorite is guaranteed, and no underdog is truly hopeless on a given day.
The key question when evaluating a moneyline underdog isn’t «will they win?» — it’s «does the price reflect a fair chance?» At +173, the implied probability on Arizona sits at roughly 37%. If you believe the Diamondbacks have a realistic shot better than that — based on pitching matchup, recent form, park factors, or any other edge — then the math is on your side.
Arizona is not a pushover. The Diamondbacks have shown throughout recent seasons that they can compete and surprise. They made it to the World Series in 2023. This is a franchise that knows how to win big games. Does that mean they win tonight? Not necessarily. But does it mean they’re capable of it? Absolutely.
The value here isn’t about blindly backing the underdog. It’s about recognizing that when a competitive team is priced at a number that implies they win fewer than 4 in 10 games, there’s a conversation worth having. Lean plays like this are where patient bettors find their edge over the long run.
Don’t bet what you can’t afford to lose, and never chase. But if you’ve been looking for a spot where the number does some of the heavy lifting for you — this might be your game.
Where the value is
Here’s a clean look at the play before you decide:
- The play: Arizona Diamondbacks Moneyline +173 (via DraftKings, ref. Caliente)
- Why: At +173, the implied win probability for Arizona is ~37% — if you believe the D-backs are more competitive than that against Atlanta on this day, the price carries genuine value for an upset lean.
- Read: This is a lean, not a lock. Baseball is unpredictable by design, and underdog moneylines carry real risk. Size accordingly.
