Who has faith in the Yankees? Despite anything you've heard, New Yorkers themselves have faith aplenty, and a howling, raucous faith it has become. It seems just the other day that Yankee Stadium crowds were booing Mickey Mantle; now the most spring-legged of them break out of the stands to run the last leg with Mickey on game-winning homers. The crowds were coming, too—69,000 for a 1959 major league record on Sunday—and the cheers welling up over the Stadium, any Yankee fan would tell you, were just a hint of things to come. Detroit fans disagreed. Since the arrival of Manager Jimmie Dykes, the once toothless Tigers, not too long ago scrabbling for seventh with the Yankees, have won 32 of their last 48 and were giving the Yankees Tiger tracks to follow to the top.
