We were playing under NFHS rules so I said he had 1 foot in so he was ok. Coach said that wasn't the OBR rule, but he understood we weren't playing under those rules. OBR doesn't seem to tell me - or more likely I coudn't find it, where if a fielder has 1 foot in foul territory, then if the P throws a pitch, its an illegal pitch/balk.

The OBR rule says the player must be on fair territory. If one foot is off he's not on.

It's implict in this interpretation from the MLBUM.

2.16 FIRST BASEMAN PLAYING IN FOUL TERRITORY
Official Baseball Rule 4.03 provides that when the ball is put in play at the start of or during a game, all fielders other than the catcher shall be on fair territory. In particular, when holding a runner on first base, the first baseman shall position himself with both feet in fair territory. There is no penalty specified for violation other than the first baseman shall be instructed to keep both feet in fair territory if brought to the attention of the umpire, or-if blatant or recurring violation upon immediate direction of the umpire. If a player, after so directed by the umpire, blatantly refuses to comply, the player is subject to ejection.

It is NOT a balk in OBR. Not ever. Just tell the fielder to get fair.
