Derek Jeter's game-winning single last night was a great piece of hitting.

"Piece of hitting," of course, describes a specific kind of hit. You would not use it to describe one of A-Rod's monster home runs to left center field. Instead, "piece of hitting" connotes artistry and precision, the kinds that come with swinging gracefully at an outside pitch and taking it to the opposite field. (The Yankees squeaked by the pesky Devil Rays, 6-5.)
