Look at your Roster "team" page. It has pitcher vs. RHB/LHP OPS.

Get familiar with the info on this page...it's a big help. I print this page for my weekly opponent before a home series. I refer to it when I look for pitching match-ups during the game (especially relief moves). I also use this page to help me set up my home lineups...I can easily see which of my hitters has a platoon advantage for each position.

Good luck!
