"I asked [pitching coach] Rick Honeycutt in December, and he told me to be prepared, because you never know what's going to happen," said Haren, who allowed Milwaukee one run in two innings. "I started preparing earlier than usual. I made 35 pitches today, with 15 more in the bullpen afterward. Getting 50 around March 1 is a little ahead of usual."
With Greinke doubtful to make the trip, the Dodgers will be choosing from Clayton Kershaw, Hyun-Jin Ryu and Haren, although all three figure to be in Australia just in case.
"If I had to pitch in Australia for some reason, this allowed me to stay on track," Haren said. "With only three weeks, one day means a lot."
Haren said his first inning was "pretty bad," but the second was "much better. I bet you the next start will be more crisp."
On playing in Australia, Haren had the script down: "It would be the chance of a lifetime. Why don't you guys all tweet that?"
