Your Beginner’s Guide to Sunday’s National Bank Open Tennis Bets (August 9)

Everything you need to know about today’s top picks—explained simply!

Why This Tournament Matters Right Now

Think of this like the "final exams" before the US Open.
The ATP (men) and WTA (women) tours are in the middle of their North American hard-court swing. This week features 1000-level events in Montreal (women) and Toronto (men)—the biggest tournaments outside of Grand Slams and the season finale.

What makes these events special:

Major ranking points on the line
Elite fields — almost all top players show up
Perfect US Open prep — same surface, similar conditions
Best "form guide" — reveals who’s hot, who’s hurt, who’s ready

What to Expect This Week

Today’s Three Best Bets (Sunday, August 9)

1. Tallon Griekspoor vs. Daniel Merida Aguilar

Bet: Griekspoor Moneyline (-125) — 1.5 units

Why Griekspoor?

Factor	Griekspoor	Merida Aguilar
Serve	Major weapon	Solid but not dominant
Short Rallies (0–4 shots)	Does "a ton of damage"	Less explosive
Long Rallies	Good	Advantage Merida
Health	"Banged up all year," looked in pain last match	Fresh, 15–8 on the year

The Simple Logic:

If Griekspoor finishes the match, he probably wins. His serve + first-strike tennis > Merida’s grinding style on fast hard courts. The only risk is his body quitting.

2. Joao Fonseca vs. Ben Shelton

Bet: Fonseca Moneyline (+110) — 1.5 units

The Tale of the Tape:

Category	Ben Shelton	Joao Fonseca
Serve	Better — huge weapon	Very good
Overall Game	Power-first, inconsistent lately	Better feel, more variety
Recent Form	"Packed with bad losses"	Rising fast
Head-to-Head	Leads series	Looking to even it up

Why Fonseca at Plus Money?

Shelton isn’t playing his best tennis right now
Fonseca matches Shelton’s power but adds touch, angles, and shot variety
On hard courts, variety > raw power when power isn’t landing

+110 means: Bet $100 to win $110 (plus your $100 back). You’re getting value on the player trending up.

3. Alexandra Eala vs. Belinda Bencic

Bet: Eala Moneyline (+104) — 1.5 units

The Matchup:

Player	Status
Belinda Bencic	"Tremendous player, capable of everything at a high level" — Grand Slam champ, Olympic gold medalist
Alexandra Eala	"Hottest player on the WTA Tour right now" — riding massive momentum, electric crowd support

Why Bet the Underdog?

Momentum is real — Eala is playing with house-money confidence
Aggression + Intensity — her style disrupts rhythm, even for elites like Bencic
Plus-money on a hot hand — +104 is a fair price for a player peaking now

Reality Check: Bencic can win — she’s that good. But at these odds, Eala is the smarter bet.

FAQ: Your Questions Answered

1. What does "ML" or "Moneyline" mean?

Simple: You’re just picking who wins the match. No point spreads, no games handicap.

Negative odds (-125): Bet $125 to win $100 (favorite)

Positive odds (+110): Bet $100 to win $110 (underdog)

2. What’s a "unit"? Should I bet the same amount?

A unit is your standard bet size (e.g., 1 unit = $20, $50, $100 — whatever fits your bankroll).
Never bet more than you can lose. The "1.5 units" is a relative confidence measure, not a dollar instruction.

3. Why are some picks only on the Pro Picks page?

The daily article highlights the top 3 high-conviction plays. The Pro Picks page is the complete portfolio — including lower-leverage plays, Challenger events, and in-day adds. Both count toward the tracked record.

4. What if a player retires hurt (like Griekspoor might)?

Most sportsbooks void moneyline bets if a player retires before completion (check your book’s rules). That’s why the Griekspoor pick has a health caveat — if he withdraws mid-match, you likely get your money back.

5. How do I track if these picks are actually good?

The VSiN Pro Picks page maintains a running record (wins/losses/units +/-) for every analyst. Transparency = accountability. Bookmark it and watch the season unfold.

Final Thought

This is the time of year where contenders separate from pretenders.
Hard courts don’t lie. The players who move well, serve big, and strike first — they’re the ones holding trophies in New York come September.

Stay sharp, bet smart, and enjoy the tennis!
