Our Alejandro Tabilo vs Alexei Popyrin prediction for today's 2:00 PM ET US Open second rounder comes with a catch: T Money likes Tabilo on paper, and is not backing him with a bet.
The moneyline sits at -115 on Tabilo, and the twelve month hard court numbers back his side clearly. But Popyrin's game carries one specific tool that lines up with a documented hole in Tabilo's record, and that is enough to keep this off the card as an official PASS.
Why T Money leans Tabilo
Tabilo's opener was the more convincing of the two. He beat Yannick Hanfmann 6-3, 6-2, 6-7(7), 6-3 in the first round, and while Hanfmann's 49 unforced errors did some of the work, Tabilo's own line backs it up: 62% first serves in, 85% of those points won, 56% of second serves won, only four double faults, and a 124-95 edge in total points played. He also put up 30 winners against 20 unforced errors, a positive balance that a bad-day scoreline does not usually produce.
That result fits his longer window. Over the past twelve months on hard courts, against opponents of comparable schedule strength, Tabilo is 21-12 (64%), with an 87% hold rate and 17% of return games won. That includes wins this year over Ben Shelton and Lorenzo Musetti, both higher-tier opponents. Popyrin's twelve month hard court mark over the same kind of schedule is 4-13 (24%), with an 82% hold rate but only 12% of return games won. That gap is the backbone of the pick.
The case against, and why it's a pass
Popyrin's own opener was not nothing. He beat Grigor Dimitrov in four sets, breaking serve six times with 33 winners against 25 unforced errors. Some of that was Dimitrov handing it over with 14 double faults, so the result reads a bit better than the underlying tennis. It is also his only completed match since an August 20 retirement against Hugo Gaston after just 30 minutes, with no reported cause, so there is not much of a post-break sample to lean on either way.
The real reason this stays a pass is stylistic, not recent form. Popyrin's first-strike serve produced a 13.3% ace rate in that Dimitrov match, and that specific shape of server, heavy first-strike, low-margin rallies, is a documented problem for Tabilo. He is 3-4 on hard courts against that archetype, converting break chances at just an 11% clip. A match like that can turn into a handful of break points or a tiebreak or two, and at that point the twelve month gap between these two stops mattering as much as which player gets the flatter service day.
The number that matters
Tabilo is priced at -115. That is not a heavy number, and by itself it would not keep a side off the card. What keeps it off is that the specific path to a Popyrin win, a clean first-strike serving day, is a real and identifiable risk given Tabilo's own history against that kind of server, not a hypothetical one.
Popyrin does have one card worth naming as a counterweight: a Roland Garros title in 2025. That result is 15 months old and came on clay, a different surface from today's hard court, so it can speak to his ceiling as a competitor but it does not carry weight against the current hard court read. It is a secondary data point, not a reason to flip the number.
The verdict
T Money's fundamentals point to Tabilo: better recent hard court form, a stronger twelve month surface split, and wins over tougher opponents along the way. But this is an official PASS, not a bet. Popyrin's first-strike serve is a specific, matched risk against a documented Tabilo weakness, and that is enough to keep the -115 off the card even with the broader numbers in Tabilo's favor.
