World No. 1 Jannik Sinner has breezed through the Wimbledon field and is featured on the All-England Club’s Order of Play.

Round 3 concludes on Saturday, and I’ve found three plays that should add to your viewing excitement.

Let's dive into the Wimbledon odds with my free picks for July 5.

Wimbledon Day 6 predictions

Jannik Sinner vs Pedro Martinez Under 27.5 games (-130 at DraftKings)

Jannik Sinner has silenced any doubts about his mental state entering Wimbledon. 

He’s blown through the first two rounds unscathed, and I don’t expect journeyman Pedro Martinez to change that.

Martinez has game, but his service return and groundstrokes lack the power to go toe-to-toe against Sinner’s monster serve and relentless east-west punishing groundstrokes.

Sinner decisively beat Martinez in their 2022 meeting on Martinez’s favorite surface (clay). Saturday is a huge third-round mismatch that Sinner should dominate, which puts the Under 27.5 match score firmly in play.

Hailey Baptiste vs Mirra Andreeva Over 21.5 games (-110 at FanDuel)

Hailey Baptiste knows how to frustrate opponents with her power and speed. 

Baptiste may not reach the Round of 16 against No. 7 Mirra Andreeva, but she’s well-equipped to push this match the distance.

Andreeva isn’t the best mover with an inconsistent service game. Because of this, she gets easily frustrated, and that’s when the wheels fall off.

Despite Andreeva’s talent, her wheels tend to flatten under pressure.

Baptiste has the game and tenacity to get into Andreeva’s head, and the American’s recent results suggest a match stretching past 21.5 games.

Daria Kasatkina moneyline (+198 at FanDuel) 

Big-hitting No. 18 Liudmilla Samsonova has breezed through her section without a hiccup, but she has her hands full against No. 16 Daria Kasatkina.

Samsonova is all about rhythm. She plays fast and hits big, and when the 26-year-old is dictating play, she's tough to beat.

Kasatkina is more deliberate, knows how to absorb Samsonova’s pace, and can hurt the Russian enough to win this match.

Saturday’s battle will be a close one, but Kasatkina, a former quarterfinalist, is undervalued.

I’ll take a stab at Kasatkina pulling off the upset.
