Return to form?: Maddon said he believes struggling RHP Andy Sonnanstine is going to step up, and he is eager to see if the right-hander can make the necessary adjustments tonight.

Sonnanstine (3-5, 7.66 ERA) gave up a career-high eight runs in three innings in his last start.

"Of course we want him to pitch at a better level than he is," Maddon said. "His ERA is very high, and he's had some difficult moments. We talked about it a couple days ago about him pitching more inside, but we've been looking even deeper, and we think we found some other items that are kind of interesting."
