When writing about sports scores, standings and standards, here's how AP style treats numbers:
* The Dodgers defeated the Phillies 10-3. (No comma between the team and the score)
* In narrative, spell out nine and under except for yard lines in football and individual and team statistical performances: The ball was on the 5-yard line. Seventh hole. In basketball, 3-point play and 3-point shot.
* In statistical performances, hyphenate as a modifier: He completed 8 of 12 passes. He made 5 of 6 (shots is understood). He was 5-for-12 passing. He had a 3-for-5 day. He was 3-for-5. He went 3-for-5 (batting, shooting, etc., is understood).
