This is one of those rare and near-impossible instances of the Diamondbacks actually being fat and happy.

Arizona still is gloating about coming from five runs down to defeat the Padres, 8-5, on the road Friday night.

That victory, though, was against rookie Ryan Weathers. Now the Diamondbacks face ace Yu Darvish and an angry Padres bunch. Darvish has a 3.16 ERA at Petco Park this season.

I expect Darvish to pitch much better than Weathers did and for San Diego to destroy Diamondbacks starter Taylor Widener, who in his last three starts spanning 12 2/3 innings has given up a staggering 15 earned runs on 18 hits, nine walks and four homers.

Each of the Padres' last five victories have been by 3 runs or more.
