2 US Open 🇺🇸 Round of 32 Match Previews:

Popyrin vs Tabilo:
Popyrin just won over Dimitrov, beat Djokovic here two years ago, and won 3-0 over Tabilo in their lone meeting at Roland Garros in 2025.

Despite this, the market prices Tabilo at 61c (-156), and the winning records agree: $32.7k on Tabilo against $7.9k on Popyrin.

Musetti vs Sweeny:
The Italian is 94c (-1567) over a qualifier, and the graded money has barely shown up.

Story and money, both matches, below 👇

[Gut Check @GutCheckBet]

Dane Sweeny, #123 in the world hit 37 winners in 2.5 sets over Moutet (retired) last round. Musetti is 20-10 on the year, and dropped just eleven games in three sets to Fery.

The graded book is thin: $1.1k of winning-record money on Musetti from one wallet, nothing on Sweeny, and the only losing-record bettor over the bar, down $239k has $3.4k on Musetti at 94c.

Musetti to win 3-0 is currently 66c (-194).

[Gut Check @GutCheckBet]

A wallet down $30.6k holds an $111.6k position on Alcaraz.

3 winning-record wallets hold Faria +6.5 games with nothing opposite. Seven hold Faria +2.5 sets.

Just a few days ago in the first round, winning-record wallets took Safiullin +6.5 games against Alcaraz. He covered. The wallet that led that bet, up $23.7k, is on Faria +6.5 tonight.

Faria vs Alcaraz (US Open) 🇺🇸

Faria took nearly four hours to beat Brooksby in the first round. Alcaraz won in straight sets against Safiullin. The market prices Alcaraz at 92c (-1150).

Everyone is on Alcaraz to win. Pre-match losing wallets have $261.7k on him at 92c.

The winning-record wallets are targeting the game spread, every one of them holds Faria +6.5 at 43c (+133).

The profitable money says close sets 👇

[Gut Check @GutCheckBet]

Alcaraz, #2 seed and the defending champion. He opened with a 6-4, 6-4, 6-4 win in his first match since April.

Faria, ranked No. 72, needed five sets to beat Brooksby on Monday, with a New York crowd against him the whole way.

@edgeAIapp This is not looking promising folks...

Expecting all outer court matches to be cancelled for the day.

Another day of rest probably helps a guy like Buse coming off a long title week.

Giron vs Buse (US Open) 🇺🇸

The last scheduled match of Day 3 at the US Open 👀

Our signal had Buse ML (+120) in that Winston-Salem final two days ago. It hit.

Tonight the profitable bettors pre-match are fading Buse 👀

Giron's case looks much worse....

Three straight losses, all on hard courts (his best surface), and a 3-8 career record at his home slam. He's never made it past the second round in his 11 appearances at the US Open.

The most profitable tennis bettors on Polymarket are backing Giron anyway at 39c (+156).

The best bettor in this market, up $233k holds $11.9k on Giron.

The worst bettor in this market, down $444k has $60k on Buse.

[Gut Check @GutCheckBet]

Ignacio Buse is 22 and just became the youngest Winston-Salem champion ever on Saturday.

He's won two titles this season, and is now the world #30. Buse won over Giron this summer at Queen's in a deciding set breaker (10-8).

He also played five matches last week en route to the title and flew straight to NY.
