I don't know whether I appreciate more the whole of Jesse Nathan's thoughts in "Baseball Has Lost Its Poetry" or the remarkable feat of placing a reference to "To His Coy Mistress" in an essay about baseball.Most of all, I get the feeling that a languorous 19th-century invention — baseball — is being forced to fit a 21st-century pace of life. Most days, most places, I already feel rushed, sensing, as Andrew Marvell wrote, “time’s wingèd chariot hurrying near.” Now I have to feel that at the ballpark, too?
