SYDNEY -- It sounds like while the D-backs' lineup for the first game of the Opening Series on Saturday is still a work in progress, a few spots are locked in.
First baseman Paul Goldschmidt will hit third as expected and the pitcher Wade Miley will hit ninth.
The only other piece D-backs manager Kirk Gibson was willing to reveal was that third baseman Martin Prado was all but certainly going to hit cleanup.
"He's arguably our best pure hitter," Gibson said.
Gibson initially tried hitting Prado in the second spot last year, but did not like the way Prado tried to take the ball to the opposite field every time.
Gibson then moved Prado down in the order, and he began driving the ball more.
Goldschmidt takes in Taronga Zoo
SYDNEY -- D-backs first baseman Paul Goldschmidt and a host of front-office executives visited the Taronga Zoo on Thursday prior to the team's workout.
The group got an up-close look at wallabies, kangaroos and a Tasmanian devil.
"It's a cool place," Goldschmidt said. "It's great to come here and see some different animals than we normally get to."
While Goldschmidt had to break away after a few hours, the rest of the group stayed behind to spend more time with the animals.
Gregorius shrugs off trade rumors
SYDNEY -- More than 7,000 miles away from Arizona, D-backs shortstop Didi Gregorius has not exactly been keeping up on trade rumors.
ESPNNewyork.com reported that the D-backs are making Gregorius available in trade discussions, apparently choosing to go with Chris Owings at short.
"I didn't know anything about trade rumors," Gregorius said after the team's workout on Thursday. "I don't really go look up that stuff. I don't really care. It's not in my hands. It's in the GM's hands. I don't have to worry about that."
D-backs manager Kirk Gibson said both Gregorius and Owings would get a start in the two-game Opening Series against the Dodgers this weekend.
The team has said it would like one or the other to be the starter with Cliff Pennington serving as the backup. However, both could wind up on the roster when the regular season resumes on March 31, because outfielder Cody Ross will open the year on the disabled list.
• The D-backs played a three-inning simulated game on Thursday to get familiar with the field at the Sydney Cricket Ground.
• Back in Arizona, Bronson Arroyo (bulging disc) threw 46 pitches in a simulated game and could still be able to start the season on time, and Brandon McCarthy threw 75-80 pitches in a Minor League game and another 15 in the bullpen.
• The D-backs are hoping to get five innings out of Archie Bradley in Friday's exhibition game against Team Australia. He was roughed up in his last Cactus League start.
"He's had a couple good bullpens since his last outing," Gibson said. "He didn't have a very good outing last time. I know he's looking forward to throwing a good game."
• Several of the players' guests on the trip as well as some support staff have been hit by a stomach flu bug, but Gibson is hoping it doesn't carry over to the team.
• A number of players, led by J.J. Putz, did the Sydney Harbour Bridge climb on Thursday.
