"Usually what we try to do is try to match these guys up with the teams they've pitched better against," Mattingly said. "We'll look out as far as we can with teams they have good matchups against."
The Dodgers begin a six-game homestand on Friday, with three games against the Padres and then three against the Phillies.
At the start of the season, Kershaw was followed by Chad Billingsley then Chris Capuano. But through the first half of the year Capuano has pitched more like a No. 2 starter than Billingsley. After Sunday's series finale with the D-backs, Capuano was 9-4 with a 2.91 ERA while Billingsley was 4-9 with a 4.30 ERA.
However, Mattingly said the order of the rotation wasn't based on ranking the pitchers.
"The real consistency with him has been inconsistency," Mattingly said of Billingsley. "You don't know what you're going to get, honestly, that's the thing. It's not like he just looks terrible, there are times he looks really good and then it's gone.
"To say that's your No. 2 starter, it's hard to say that honestly. Right now you have to look at [Capuano] as the guy you give the ball to, you get a good outing and he keeps you in the game. You look at him as your No. 2."
