LOS ANGELES -- The ripple effect from the D-backs' 12-inning, 8-5 victory on Tuesday night over the Dodgers is that Zack Greinke will now start Thursday in the opener of a four-game series at home against the Washington Nationals.
T.J. McFarland had been the D-backs' likely starter Thursday, but he was needed for the final 1 1/3 innings Tuesday, picking up the victory after retiring all four batters he faced.

Greinke (3-2, 4.10 ERA) will now take the mound on his regular four days of rest after last pitching in Saturday's victory over the Houston Astros. Manager Torey Lovullo had planned on using Monday's off-day to give Greinke an extra day of rest during this turn through the rotation.
"[Pitching coach] Mike Butcher brought up a really good point, and he said this is the time of the year when pitchers want to get pumping and grooving on their schedules every fifth day," Lovullo said. "There is a place and a time for the extra day and when it's part of the schedule, we will give it to them."
Greinke had a long eight-day gap between his first and second start of the season, then had six-day gaps between his next three starts. Thursday will be his fourth consecutive start on regular rest.
Lovullo said that Matt Koch will start Friday against the Nationals, but Saturday's starter is still to be determined. Candidates for that outing include left-hander Troy Scribner and right-handers Taylor Clarke (D-backs' No. 7 prospect, Jake Buchanan and Albert Suarez.

The rotation scramble actually goes back to when Braden Shipley was put on the disabled list Tuesday with elbow tendinitis. Shipley likely would have been asked to give the D-backs length late in the extra-inning victory. McFarland was pressed into that role instead.
Lamb on track in rehab
Jake Lamb, on the disabled list with shoulder inflammation, had an off-day from his rehab schedule Wednesday, but he remains on track to play in a game next week in extended spring training, Lovullo said.
Lamb took swings, fielded ground balls and threw across the infield Tuesday. Wednesday's day off was designed to see how his shoulder responded to the long throws. If Lamb is able to return to his regular schedule of baseball activity, he will see game action.
D-backs' Honorary Bat Girl selected
Mary McGonegle of Gilbert, Ariz., was selected as the D-backs' Honorary Bat Girl for Sunday's Mother's Day game against the Nationals, as each MLB club participates in the annual "Going To Bat Against Breast Cancer" initiative. McGonegle, who is marking her seventh year as a breast cancer survivor, has a brother and sister-in-law who are each battling cancer.
Worth noting
• Shelby Miller, who had Tommy John surgery last year, was fine after a recent bullpen session and is scheduled to start in an extended spring training game Friday.
• Left-hander Robbie Ray, on the DL with an oblique strain, did exercises in the pool as well as some shoulder-strengthening exercises on Wednesday.
