Martin Miguel Vassallo Argüello (born February 10, 1980 in Temperley, Argentina) is an inactive professional male tennis player from Argentina. His career-high ATP singles ranking is World No. 47, achieved in April 2009 shortly after reaching the semifinals of Acapulco.
He turned pro in 1999. Over the course of his career, he has represented both Argentina and Italy.
At the 2006 French Open, he reached the fourth round of a Grand Slam event for the first time in his career. He entered the tournament as a qualifier and beat Paul Goldstein of the United States in the first round (6–2, 6–0, 6–3), #21 seed Sébastien Grosjean of France in the second round (1–6, 6–4, 4–6, 7–5, 6–2) and Raemon Sluiter of the Netherlands in the third round (2–6, 6–4, 6–3, 3–6, 6–1). In the next round he lost to David Nalbandian.
In late 2007, at the Orange Prokom Open in Sopot, Poland, Argüello was embroiled in a betting scandal after his match against world number four Nikolay Davydenko. The match saw Davydenko retire with the scores at 2–6, 6–3, 2–1. Gamblers betting on the match displayed irregular betting patterns and a total of £3.4m was paid out on it, ten times the normal amount for a match at this level. Eventually, Betfair voided all bets on the match. Neither Argüello nor Davydenko have been formally charged with any offence by the ATP.
