"JFK," "Thirteen Days," "Dances With Wolves," to name a few are not about water or baseball. His most famous part would likely be "Bull Durham" which is arguably the best movie every made about baseball and he was in one of the other good movies about baseball, "Field of Dreams." I can't think of any other "water" movie other than "Waterworld" which gained its notariety over the bloated budget.
He's been in more than a handful of films and yet one of my favorite roles is the rakish vagabond in "Fandango."
If you look at his entire filmography, he's really tackled a wide range of roles including the villain.
I did like his Robin Hood but it was nearly impossible to replace Errol Flynn.
Here's the link to his filmography:

"Open Range" is an excellent Western which is about a baseball player who swims across rivers.
