When I was wondering about Matt Stairs before the season, I found that 68% of their starters were righties. I would assume that it's close to the same percentage in the N.L., but I can't say for sure. But if no one else knows - or if you're unwilling to do the work - then it's a good starting point.

68% is a good starting point.

Rule of thumb you can expect a ratio of 3 lefties to every 10 starters or 30 % lefties 70% righties.

Using this method Roberts will play 7 games in 10 but will then pinch hit and pinch run often in the games he doesn't start.
