The ATP Challenger Tour, previously called the ATP Challenger Series, is a series of international men's professional tennis tournaments considered as the second highest level of competition.
The ATP Challenger Tour is administered by the Association of Tennis Professionals. Players who succeed on the ATP Challenger Tour earn sufficient ranking points to become eligible for main draw or qualifying draw entry at ATP World Tour tournaments.
Players on the Challenge Tour are either young players, those who fail to qualify for ATP events, or former ATP winners looking to get back into the big tour.
The 2017 ATP Challenger Tour calendar comprised of around 150 tournaments, with prize money ranging from $50,000 up to $150,000.
A typical WTA over under bet looks like:
| Krajinovic, Filip | Over: 22 | -105 |
| Djere, Laslo | Under: 22 | -115 |
In the example above, betting $105 on "Over 22 games" wins you $100 if the total points of the match is 23 or more. Meanwhile, betting $115 on "Under 22 games" wins you $100 if the total points of the match is 21 or less.
So if the match ends with a score of 6-4, 6-4 (for a total of 20), "Under" bettors win. But if the match ends with a score of 6-4, 4-6, 6-4 (for a total of 30), "Over" bettors win.
If, for some reason, the match ends with a total of 22 points, the bet is called a tie or push and all bets are returned. To avoid this, odds makers add a half point on the totals.
