Tennis parlay today: Our best bets for Day 4 of the Australian Open 2026 (+953 odds)

The opening tennis Grand Slam of the year is underway, with Day 4 of the Australian Open 2026 offering another massive slate of matches throughout the night, and for tennis bettors, this type of volume creates excellent parlay opportunities.

While the public scrambles just to find an edge at Melbourne Park, we have isolated four specific tennis bets where the numbers point to significant value.

For our best parlay on Day 4, we are targeting four games spread plays—three from the Men's draw and one from the Ladies' draw. By combining these edges, we have constructed a tennis parlay that turns high-confidence data into a +953 play, and our spirits are sky high after nailing both our Day 2 parlay at +880 odds and also our Day 3 parlay at +570 odds.

Here is the breakdown of the tennis best bets we've used to craft a parlay today, with picks in order of highest probability.

Tennis parlay - Australian Open 2026

Leg 1: Novak Djokovic -8.5 Games (-140)

Matchup: F. Maestrelli vs. N. Djokovic

Time: Jan 20, 7:00pm (ET)

We open our Day 4 tennis parlay with the ultimate mismatch. Novak Djokovic faces Francesco Maestrelli, and the spread is set at a daunting -8.5 games. While asking a player to cover such a large number usually carries risk, our data suggests this is the safest play on the board.

Our model assigns a massive 73.0% probability to Djokovic covering, generating a staggering 14.7% edge.

The Reasoning: This is among the highest edges we have identified all tournament. Djokovic’s return game is perfectly suited to dismantle an opponent of Maestrelli’s experience level. When looking for the anchor of your best parlay today, this is it—the metrics indicate a blowout is not just likely, but expected.

Leg 2: Carlos Alcaraz -8.5 Games (-150)

Matchup: C. Alcaraz vs. Y. Hanfmann

Time: Jan 20, 10:00pm (ET)

Following Djokovic, we look to another giant of the men's game. Carlos Alcaraz takes on Yannick Hanfmann with an identical spread of -8.5 games. Much like the first leg of today's parlay, the market hasn't priced in the gap in class correctly, creating one of the strongest tennis bets of the slate.

We project Alcaraz covering this spread 72.3% of the time, resulting in a double-digit 12.3% edge.

The Reasoning: Hanfmann plays a heavy game, but Alcaraz’s speed and defense on these courts will force him into errors. We are backing the Spaniard to cruise to a straight-sets victory, making this a high-confidence addition to your parlay today.

Leg 3: Priscilla Hon +5.5 Games (-108)

Matchup: I. Jovic vs. P. Hon

Time: Jan 21, 4:40am (ET)

For the third parlay leg, we pivot to the women's draw for significant underdog value. Australia's Priscilla Hon faces the young American Iva Jovic. While Jovic is the favorite, the 5.5-game cushion for Hon is simply too large given her experience and home-court advantage.

Our simulation gives Hon a 63.6% probability of keeping this close (or winning), offering a robust 11.7% edge at -108 odds.

The Reasoning: Finding a double-digit edge on an underdog spread bet is rare. We don't need Hon to win the match for this leg of the tennis parlay to hit; we just need a competitive performance. The data screams value on the Aussie staying within the number.

Leg 4: Frances Tiafoe -4.5 Games (-110)

Matchup: F. Tiafoe vs. F. Comesana

Time: Jan 21, 4:10am (ET)

We close out the best parlay for Day 4 with Frances Tiafoe. Facing Francisco Comesana, Tiafoe needs to cover a modest 4.5-game spread. On a hard court, Tiafoe’s dynamic athleticism gives him a distinct advantage over the Argentine clay-courter.

Our model sees Tiafoe covering this line 62.2% of the time, creating a 9.9% edge.

The Reasoning: Comesana will struggle with the pace of play Tiafoe dictates. A 4.5-game spread can be covered in a tight three-setter or a comfortable four-setter. With nearly a 10% edge, this is one of the smartest tennis bets available to round out the ticket.
