There has been no major mechanical adjustment, no addition or subtraction from the repertoire, no drastic change in game plans, Brandon McCarthy says.

Why the Diamondbacks right-hander is suddenly having so much success after having had so little earlier this season is a question he can't fully answer. His best guess – or, at least, the one he hopes is right – involves the balancing out of the universe. And he hopes the re-balancing continues.

"I'm hoping it's just kind of law of averages and it's just kind of tipping back in my favor," McCarthy said after throwing seven scoreless innings in the Diamondbacks' 4-3 win over the San Diego Padres on Saturday night.

"I really don't feel like there's been anything different in the last few starts over the first few. Those, I felt good in, just the results weren't there. This all kind of feels the same. I'm glad that everything feels consistent, feels the same. Now I just need to make sure the results stay this way and not the other way."

In his first three starts, McCarthy permitted 17 earned runs in 19 2/3 innings. Those were dark days for the Diamondbacks' rotation, a unit that somehow got trounced in the early innings of nearly every game.

But, in the same way that McCarthy is enjoying a resurgence, so, too, is the rest of the staff.

Starting in the fourth inning on Wednesday night, Diamondbacks pitchers didn't allow a run for 24 consecutive innings, a streak that ended in the ninth inning on Saturday. Two formerly struggling right-handers – McCarthy and Bronson Arroyo – led the way the past two nights, combining for 14 scoreless innings.

Though it might be easy to downplay the staff's performance the past two days since it came not only against the light-hitting Padres but also in the pitcher-friendly Petco Park, it's worth noting that the Diamondbacks couldn't do the same last month against the New York Mets or Chicago Cubs, two teams that entered series with woeful offensive numbers but left having swung the bats well.

"It's just nice to be contributing," McCarthy said. "I know for me and for Bronson, it's a relief when you're not the goat every time out.

"We're not winning or losing games anymore in the first or second inning because we've given up so many. Now, it's just being able to battle for nine innings, and I think we're doing a better job of that."
