I just watched Ookiku Fuikabutte or Oofuri for short which is a series on baseball. My daughter recommended it. Even her boyfriend likes it. There's also Whistle for soccer, Eyeshield 21 for football (though I haven't seen it), Prince of Tennis (though I think it is like by females more), etc. I agree Hikaru no Go is an good choice. My youngest daughter watched it when she was in her early teens.
As for subtitles, let him know its ok to have to pause it and read them...and that he's not alone if he does.
