Mark Buehrle, SP (CHW): Mark Buehrle, who is owned in 31.2% of ESPN leagues, is having his best month of the season. We know that he's capable of being an ace, but we haven't seen it up until this month. He's only 5-6 with a 4.04 ERA this season, but in June he has performed significantly better. This month, he is 3-0, with a 1.89 ERA, 20:6 K:BB ratio and a 0.97 WHIP. It's hard to judge whether Buehrle is a good long-term investment because he was wildly inconsistent last year. For now, ride out his good stretch.
