It's not like they haven't beaten good teams. Most good teams pad their record against bad teams. They have beaten some (but not many) good teams, but the bigger point is that they don’t have many games against bad teams to pad their record against after the break. And if they just play .500 ball the rest of the way (which won’t be easy) that won’t be good enough for a wild card spot. It depends on how you define a "good" team. I define it as teams currently above .500. St. Luis (x3), Colorado, Arizona (x2), Phillies, Cubs and Atlanta are series they have won against "good" teams. Cubs (x2), Cleveland and Phillies are series they have lost to "good" teams. They split a series with Cleveland as well. They are 7-3 against the Reds. That's 8-4-1 in series against "good" teams. I thank that qualifies as wins against more than "some".
