Alan Magadan vs Richard Mallory Prediction — ATP Davis Cup - World Group II (2026), Sunday, September 20, 2026

Sunday's Alan Magadan vs Richard Mallory prediction looks like the easiest read on the Davis Cup World Group II slate. The market has Magadan at -3333, which prices him as close to a sure thing as tennis gets. The match is set for 12:00 PM ET on Sunday, September 20.

The model is on Magadan's side of the ledger too. But this one is a PASS on the card. That means we are not backing it, at any price, on this rubber. Here is what the numbers actually say, and why the gap between "probably right" and "worth a bet" matters here.

Why the model likes Magadan

Magadan opened the tie on Saturday with a 6-4, 6-1 win over Daniel Phillips in 89 minutes on hard courts. He broke serve five times and only lost his own serve once all match, which is the kind of return pressure that travels well into a second rubber. Phillips helped him out with three double faults in the final game, but the break count on its own says Magadan was doing the heavier lifting.

That result folds into a stronger picture than his results sheet suggests at a glance. In August, Magadan won three straight hard-court matches in Cancun before losing to Coleman Wong. Point-level stats from those wins show he was winning 63 to 76 percent of points on his first serve and 50 to 70 percent on his second across the three matches. That is a real, current, same-surface run of serve control, not a one-off.

The case for Mallory, and why it is not nothing

The model's own risk notes flag exactly why this is not a laydown: Mallory has already shown he can play at a level well above this. He won a title in July, sweeping five matches including a deciding tiebreak in the final, built on aggressive, front-foot tennis. If he reproduces that level and gets after Magadan's second serve early, he can turn Magadan's shakier service games into the kind of quick breaks that flip a match before it settles.

The problem is what happened after that title. Mallory retired from his next tournament match in July, and in his most recent completed hard-court match, an August 16 loss, he won just 33 percent of his second-serve points and hit six double faults across 83 minutes. That is a big gap under Magadan's 50 to 70 percent second-serve numbers from the same span, and it is Mallory's own most recent form line, not something borrowed from his July peak. The title run is real, but it came at a lower-tier wildcard event, and the service numbers since do not confirm it carried forward.

Why it is a PASS and not a bet

To be clear about the label: this is an official PASS. The model is not putting money on Magadan here, and it is not naming Mallory as a live underdog play either. Nothing about the analysis above should be read as a soft or low-conviction lean toward either side. It is simply not a bet the model is making on this rubber, and the reasoning is not being spelled out beyond what is written here.

Part of what makes this one hard to grade cleanly is Mallory's own record. There is no reliable read on his form before last September, and his 2026 log is a mix of two wins in lower-level qualifying, a retirement, a second retirement in July, and a canceled match in August. His actual current match fitness heading into Sunday is not settled, since both players remain in the mix for Sunday doubles as well, which leaves real uncertainty about workload and rest that a raw form line does not capture.

The verdict

Magadan's game and form point the right direction on paper, backed by real same-surface break numbers and a clean opening win. But between Mallory's unresolved recent match log, the retirement history, and the second-serve red flag hanging over an otherwise dangerous ceiling, this stays off the card. PASS.
