The problem – if it can even be phrased that way – with getting off to an unexpectedly positive start to the baseball season is that it can lead to some delusions, at least from this chair. If the Washington Nationals are .500 through 36 games – which is what they are after Wednesday’s enthralling 12-inning, 7-6 loss to the Baltimore Orioles – couldn’t they be better than that if they added talent to a roster that has obvious holes?
