Over the past 17 games, San Diego relievers have allowed just seven runs over 47 1/3 innings, posting a 1.33 ERA and .189 opponents' batting average. That included a stretch of 24 2/3 consecutive scoreless innings, snapped on July 21 against the Rockies.
In Saturday night's 4-2 loss to the Marlins, lefty Alex Hinshaw gave up just one hit over two innings -- Justin Ruggiano's solo homer in the seventh.

"It's more of a consistent mindset of where they're going to pitch in games, what roles, what innings, and I think that leads to a little bit more consistent performance."
