"We may make a bit of an adjustment, just to split up our left handers," Weiss said. "It'll be De La Rosa to start, we'll stay in line that way, but we may change it up a little bit the rest of the rotation. Split up the lefties, split up the young guys, that type of thing."
Regardless of how it all shakes out, Weiss and the Rockies simply hope the rotation builds off the momentum it has generated recently.
Highlighted by Tyler Chatwood's eight-inning complete game on Saturday, the Rockies rotation has posted a 2.35 ERA in the past seven games before Sunday's first-half finale against the Dodgers.
In the last seven games, the Rockies rotation has thrown 38 1/3 innings while allowing 10 runs and holding opponents to a .204 batting average.
"I'm encouraged by the way we played and the way we competed and the way our pitchers -- our starters in particular -- have performed," Weiss said.
