I saw this movie (american) a few years ago but I think it came out during the mid/late '90s or early '00s, rough description is: A high school or college baseball player enters into a long distance relationship with his girlfriend while she travels, shortly after she leaves, the guy is at a bar & meets a hot red head & goes for a drive with her, she talks him into sex & they drive to a baseball field & **** on the back seat, a while later in the movie they sail on a boat & **** on the boat, his girlfriend comes back after a few weeks & he dumps the red head to get back with his girlfriend, the redhead starts causing trouble even going as far as wrecking his baseball career, & the guy & his girl break up, the girl moves in with the redhead without realising she's the one her bofriend slept with, when she find out the redhead causes more trouble & the guy & his girlfriend get back together.
I hope my description is accurate & someone can tell me the name of this movie, thanks, sven
