What Does “Over 38.5 | 3rd Quarter – Over/Under” Mean?
In basketball betting, “Over/Under 38.5 – 3rd Quarter” is a quarter-specific total points bet. Instead of betting on the whole game’s score, you’re betting on how many combined points both teams will score in the 3rd quarter only.
- You are betting on whether the total points in the 3rd quarter will be:
- Over 38.5 points (39 points or more), or
- Under 38.5 points (38 points or fewer)
The “.5” (half point) exists to eliminate the possibility of a tie (called a “push”). So your bet either wins or loses — no draws.
How This Works With Teams (Simple Example)
Example 1: Lakers vs Warriors
Imagine this betting line:
Los Angeles Lakers vs Golden State Warriors
3rd Quarter Total: Over/Under 38.5
Let’s say the 3rd quarter ends like this:
- Lakers score: 22 points
- Warriors score: 20 points
- Total = 42 points
Since 42 is greater than 38.5, the Over 38.5 bet wins, and Under 38.5 loses.
But if the quarter ends:
- Lakers: 18
- Warriors: 19
- Total = 37 points
Now the Under 38.5 bet wins.
Why Bookmakers Set These Lines
Bookmakers analyze:
- Team offensive and defensive ratings
- 3rd quarter scoring trends
- Pace of play
- Coaching halftime adjustments
- Player rotations after halftime
The 3rd quarter is especially important because:
- Coaches adjust strategy at halftime
- Starters usually play more minutes early in the 3rd
- Momentum swings often happen after halftime
That’s why this quarter is very popular in live and pregame betting.
