Parlay: San Francisco Giants VS Arizona Diamondbacks 2025-09-17

Arizona Diamondbacks vs. San Francisco Giants: A Same-Game Parlay Masterclass
By The Sports Oracle with a Side of Sarcasm

1. Parse the Odds: Numbers Don’t Lie (Mostly)
The Arizona Diamondbacks (-116) are slight favorites to beat the San Francisco Giants (+102) in this September 17 clash. Translating that into implied probabilities: Arizona’s 53.7% chance to win vs. San Francisco’s 48.8%. Not exactly a landslide, but the D-Backs have a 51.8% win rate as moneyline favorites this season, while the Giants struggle at 46.8% as underdogs.

The total is set at 9 runs. Both teams have a habit of breaking it—Arizona’s games have gone Over 48% of the time (72/150), and San Francisco’s? A staggering 70/150 Overs. With Arizona’s offense (5.0 R/G, 204 HRs) facing Giants starter Kai-Wei Teng (7.54 ERA, “volcano-level” control), this looks like a recipe for run production.

Key Matchup:
- Arizona’s Zac Gallen (4.84 ERA, 157 Ks) vs. Giants’ Kai-Wei Teng (7.54 ERA, .289 OBA).
Gallen’s a “screen door”—he keeps things contained but isn’t shutting the flood out. Teng, meanwhile, is a leaky fire hydrant. His last start? Four earned runs in four innings. Not exactly “ace” material.

2. Digest the News: Injuries, Lineups, and Why Your Uncle Steve Shouldn’t Pitch
Arizona’s injury report reads like a cast of The Walking Dead: Tyler Locklear (elbow), Lourdes Gurriel Jr. (ACL), and Corbin Burnes (elbow) are all on the IL. Ouch. But their core—Corbin Carroll (.542 SLG, 30 HRs), Geraldo Perdomo (.290 BA, 97 RBI), and Ketel Marte (.376 OBP) are healthy and hungry.

The Giants? They’re fielding a “nearly full deck,” but their offense (.237 BA, 161 HRs) is a flickering candle compared to Arizona’s bonfire. Rafael Devers (31 HRs) and Jung Hoo Lee (.264 BA) will need to conjure magic to keep up.

Plot Twist: San Francisco’s starter, Teng, has an ERA that makes a sieve look competent. He’s allowed 7.54 runs per game this season. For context, that’s like letting your toddler defend a castle against a hurricane.

3. Humorous Spin: Because Baseball Needs More Laughs
Let’s talk about Teng. His ERA is so high, it’s got its own ZIP code. If he were a toaster, the “error” light would be permanently on. Facing Arizona’s offense—led by Carroll, who slugs like he’s paid by the home run—is like handing a toddler a loaded cannon and saying, “Don’t shoot the neighbors.”

Meanwhile, Gallen is the “I’ll try not to embarrass us” starter. His 4.84 ERA isn’t great, but it’s not a cry-for-help either. Think of him as the guy who always shows up to the office party with a half-finished joke. It’s… serviceable.

The Over/Under? Nine runs. With Teng on the mound and Arizona’s bats going nuclear, this game could end 12-10 after the 12th inning. The Giants’ defense might as well be made of Jell-O.

4. Prediction: The Verdict from the Oracle of Odds
Same-Game Parlay Pick: Arizona Diamondbacks Moneyline (-116) + Over 9 Runs (-110).

Why? Because Teng’s ERA is a broken dam, and Arizona’s offense is a flood. Gallen won’t shut the Giants down, but their lineup isn’t potent enough to capitalize. The D-Backs win outright and do so in a high-scoring romp.

Implied Probability Check: Arizona’s moneyline implies a 53.7% chance to win. The Over 9 runs has a 51.3% implied probability (based on -110 odds). Combining both? A parlay with roughly a 27% chance to cash. Not bad for a game that smells like a “run-fest.”

Final Jeer: Bet on Arizona to win and the game to go Over. If you’re a Giants fan, maybe invest in a time machine. Or a better pitching coach.

“The Diamondbacks aren’t just favored—they’re the only team not named ‘Kai-Wei Teng’s Worst Starts.’”
