ATP tennis betting history, player by player
Explore 12,231 matched results across 542 players from 2022–2026. Every included bet uses a hypothetical one-unit stake. Betting against a player means backing their opponent at the opponent’s recorded odds.
Favourite and underdog describe the named player. Historical returns include winning and losing bets and do not predict future profits. Qualifying, Challenger, ITF, team events, unfinished matches and unresolved records are excluded. The latest included match date can be earlier than the date the archives were checked.
How is player ROI calculated?
ROI is net profit divided by total stakes, expressed as a percentage. At a flat stake of 1u, a win at 2.50 returns 1.50u profit and a loss costs 1u. The table includes both, using the recorded price for the side you select.
What counts as a favourite or underdog?
The favourite has the shorter of the two recorded prices; the underdog has the longer price. Equal prices appear in all matches but neither split. These labels always describe the named player, including when you choose to bet against them.
Are these Il Margine’s published tennis picks?
No. This is a historical research tool showing what backing each player or opponent would have returned. Our published tennis tips and results are tracked separately.
