Wow, it took 14 posts (second time through the order if your brain is baseball-wired) for someone to go with the hit joke. Color me impressed.
As for answers, my only new thing to add would be this:
Based on my limited understanding of the somewhat recent fielding update, the year of the player influences fielding circumstances. So if you went with only 19th century hitters, you'd theoretically up the number of errors made by the other team. So left-handed, high average, old dudes?
