PHOENIX -- Brandon Lyon was trying his best to put Tuesday's rough outing behind him.

"You don't want to look to the past, you want to look to the next day and that's what I'm going to do," he said.

That doesn't mean that Lyon didn't do some serious soul-searching as to why he allowed three runs on four hits in one-third of an inning, turning a 7-3 game into a 7-6 nail-biter.

"I was just falling behind hitters and not throwing enough strikes," he said. "It was a situation where balls weren't going at people, they were getting hits where when you're going good they're being hit at somebody. It's just a matter of going out there and staying aggressive and get back to that point where I'm going right at them and getting ahead."

Three of Lyon's last four outings have not been good, with the lone positive one being on the road. But Lyon says he likes pitching at Chase Field.

"It's just by coincidence that lately I haven't been pitching well at home," he said.

While D-backs manager Bob Melvin remains confident in his closer, he has asked him to make a little adjustment in his pitch selection. Lyon has four pitches, which is rare for a closer, and Melvin said he thinks Lyon has been relying too much on just his fastball and curve and would like him to work in his changeup and slider more.

"That's been addressed," Melvin said.

The three games in which Lyon struggled have been non-save situations. While Lyon admitted to a different feeling in games the team is way ahead or behind, he said the four-run lead Tuesday night didn't fall in that category.

"Last night I still have adrenaline going," he said.
