His walk rate in 2013 was even against both, he walked at a higher rate against RHP in 2012. His K% was higher against LHP this season and even in 2012. He does have a higher line drive rate against LHP. Personally, I'm not ready to say he's a liability against RHP vs. LHP, but that's just me.
All you really need to do is watch and see Frazier repeatedly chasing breaking pitches in the LH Batters box and hitting weak flies into the OF to know why the HR/FB dropped. He'd be a lot better if he didn't have to face RHP with good breaking balls. He'll be 28 in February. I'm not holding my breath for improvement. He is what he is and if it was my team I'd build it on those assumptions. If he improves and ends up manning 3B for 10 years great, I just wouldn't count on it and I'd plan the team as if that isn't happening.
