What is 1st Half – Over/Under in Basketball?
This is a totals bet where you predict whether the combined points scored by both teams in the first half (1st and 2nd quarters) will be Over or Under a line set by the bookmaker.
Overtime does not count since the bet only covers the first half.
For example:
- Lakers vs Warriors – 1st Half Total Line: 112.5 points
- Over 112.5 → If both teams score 113 or more points combined in the first half, you win.
- Under 112.5 → If both teams score 112 or fewer points in the first half, you win.
Key Factors to Analyse
When betting 1st Half Over/Under, focus on early-game scoring trends rather than full-time stats:
- Team Tempo (Pace of Play)
- Teams that play at a fast tempo (like Golden State Warriors or Sacramento Kings) often rack up points early.
- Slower-paced teams (like Miami Heat) may lean toward Unders in the 1st half.
- 1st Half Scoring Averages
- Check how many points a team scores and concedes in the first half.
- Example: Boston Celtics average 58.3 points scored and 51.7 conceded in 1st halves → High-scoring 1st halves.
- Home vs Away Performance
- Some teams start stronger at home and slower on the road.
- Example: The Denver Nuggets tend to have explosive 1st halves at home due to altitude advantage.
- Defensive Intensity Early
- Defensive teams (e.g., Milwaukee Bucks) often limit opponents early, leading to lower 1st-half totals.
- Fatigue & Scheduling
- If a team played the night before (back-to-back), defenses may slack in the 1st half → leaning Over.
- But if a coach rests key players early, it can lower scoring → leaning Under.
Example with a Team
Example Match:
Brooklyn Nets vs Indiana Pacers – 1st Half O/U line: 115.5 points
- Nets’ 1st Half Stats: Average 57 points scored and 60 conceded → Total 117 points per 1st half.
- Pacers’ 1st Half Stats: Average 59 points scored and 55 conceded → Total 114 points per 1st half.
Combined average = 115.5 points → Right at the bookmaker’s line.
- If Nets and Pacers both push the pace (fast transition teams), betting Over 115.5 has value.
- If Nets are missing a key scorer (e.g., Cam Thomas), then Under may be smarter.
Betting Tips for 1st Half Over/Under
- Check Recent Trends – Look at the last 5–10 games for 1st half totals, not just full games.
- Target High-Pace Matchups – Two offensive-minded teams = higher chance of Over.
- Consider Defensive Matchups – Elite defensive squads often force an Under in the first half.
- Look at Motivation & Lineups – Star scorers resting, or defensive starters back from injury can swing the outcome.
- Live Betting Option – If the first quarter is much higher/lower scoring than expected, the bookie will adjust 1st-half totals → value can appear live.
Practical Betting Example
- Game: Golden State Warriors vs Sacramento Kings
- Line: 1st Half O/U 118.5
- Analysis:
- Warriors average 60 points in 1st halves, Kings average 61 points.
- Combined = 121 points per half (above the line).
- Both teams rank in top 5 for pace.
- Bet: Over 118.5 → High probability based on stats.
In short: 1st Half O/U betting in basketball works best when you study team tempo, scoring splits, and defensive intensity in the opening quarters.
