Julie Kane’s “Particle Physics” at Poetry Daily invokes both baseball and eternity.

(As does Nancy Willard’s Things Invisible to See, which I’ve given as a “you must read this” gift at least twice. And which in turn reminds me of Steve Kluger’s Last Days of Summer, which I once loaned to a baseball-loving minister who told me later she’d enjoyed it enough to give a copy to another friend as a present, and yes, knowing that pleases me mightily.)
