Arizona might have the last laugh in this year's expansion derby after all. The Diamondbacks entered the weekend on the verge of overtaking Tampa Bay for the first time this season in the unofficial battle for best inaugural-season record.

It's quite a feat, considering the Diamondbacks' awful 8-31 start. But last week, Arizona matched its season high with a four-game winning streak and celebrated going 28-32 in a 60-game stretch."We like how our May was better than April, our June was better than May, and our July is better than June," manager Buck Showalter said. "It's real important for these players to continue to understand the long-range process of being consistent."
