I am going to Fenway park for my first time. I am a Brewers fan and they will be in town. Best tickets?

I will be in Boston and may, and my Dad and girlfriend wil lbe meeting me. We are looking to go to a saturday game at fenway. I can get tickets for about $50-60 a piece in the bleachers, 28 rows up. Are these bad? Am I better off scalping them the day of the game? thanks!
