There's not much to say. The Yankees didn't make any mistakes. Their pitcher just gave up one more key hit than the other guy. One-run losses are the universe's way of saying that some days you get the bear, some days the bear gets you (and as Casey Stengel said, on cloudy days you use a fastball pitcher).
A-Rod made the last out, which will surprise none of his many detractors.
Now the Yankees will have to win two of three games at home, which is, of course, entirely possible.
