Wood has not pitched since March 9
Wood, who is recovering from bursitis in his right shoulder, threw 63 pitches over four-plus innings on a back field at the Cubs' HoHoKam Park facility.
Wood was supposed to start Thursday against the A's but his lower back tightened up and the Cubs scratched him from the start.
Pitching coach Larry Rothschild said Wood's simulated game was a success.
"He threw the ball well and added up some pitches, which is good, and got to work on some things," Rothschild said.
Wood, who is scheduled to pitch Tuesday against the Brewers, is also slated to pitch the team's home opener April 8 against Milwaukee at Wrigley Field.
The 27-year-old right-hander has not pitched since March 9, when he left his start against Texas after complaining of tightness in his right shoulder.
The three-time Cy Young Award winner went to a hospital for X-rays, which were negative. He plans to return to the mound next Tuesday or Wednesday and still expects to be ready to pitch Opening Day on April 4 in Cincinnati.
"It's a matter of one or two more days and I'll feel better. I'm feeling a lot better already," Martinez said at the Mets' complex in Port St. Lucie, Fla. "Right now we just don't want to take any chances on making it worse or being in jeopardy for Opening Day. Opening Day, without a doubt, if I play it careful right now, it's going to be there for me."
The 33-year-old right-hander has had trouble with his shoulder in the past, but his back has never been a problem.
Martinez, who has looked sharp all spring, thinks he might have pushed himself too hard after his last start, a five-inning effort against the Dodgers last Sunday.
His back began bothering him when he worked out Tuesday, and he felt stiffness during his side session Wednesday. But Martinez and the Mets said they are not concerned.
"I'm just being cautious. To me, it's not a big deal. I'm just getting my guys healthy and ready for the season," rookie manager Willie Randolph said.

Carpenter pitched five solid innings, giving up three runs and six hits while striking out eight, and the Cardinals tied the Tigers 4-4 in a game called after nine innings because of rain.
The right-hander was 15-5 with a 3.46 ERA in his comeback season of 2004 after two lost years following shoulder surgery. Then, just weeks before the playoffs, he sustained nerve damage in his right biceps, forcing him to miss the postseason.
"I haven't given it a thought this spring," Carpenter said.
All three runs allowed by Carpenter came on Magglio Ordonez's three-run homer in the third inning. Carpenter said he probably wouldn't have thrown the same high-inside fastball during the regular season.
Cardinals manager Tony La Russa has named Carpenter his Opening Day starter against Houston on April 5.
"I'm excited but I truly believe that anyone on our five-man staff is just as deserving," Carpenter said. "The way we feel this year is the way we felt last year, that we have five pitchers who go out there and give us a shot to win. We have five aces."
Sabathia hurt his right side while warming up for a spring training start earlier this month. On Thursday, he threw 45 pitches off a mound and said he expects to return to the rotation by mid-April.
Until then, reliever Jason Davis will take Sabathia's spot in the rotation, and the club has two relief slots to fill.
The Indians also optioned reliever Kaz Tadano to Triple-A Buffalo. The Japanese right-hander went 1-1 with a 4.65 ERA in 14 games for Cleveland last season.
The Indians also reassigned outfielder-first baseman Andy Abad, utilityman Mike Kinkade, outfielder Jeff Liefer, outfielder John Rodriguez, pitcher Denny Stark, catcher Dusty Wathan and pitcher Chad Zerbe to their minor-league camp.
Cleveland has 32 players on its spring training roster.
Glanville, 34, was 10-for-47 with two RBI in 19 spring training games.
"The timing is that I figure we'll give him a week to see if he can catch on with somebody else," manager Joe Torre said. "He's a guy that is easy to pull for. But with a couple other guys in the mix, offensively he struggled. All the other parts of his game, the experience, are certainly a plus, but we just felt that he was the one we wanted to let go right now."
Glanville, a non-roster invitee to spring training, hit .210 with two homers and 14 RBI in 87 games last season with the Phillies.
"You have to make a decision, it's getting late in camp," Glanville said. "It's kind of a relief just to know the situation."
Glanville hopes to catch on with another team.
"I'm just going to see what happens," he said. "I'm going to kick back and stay ready. I still have some baseball in me."
Oakland manager Ken Macha made it official Thursday.
It will be the first Opening Day start for Zito, the last remaining member of Oakland's Big Three.
Manager Lee Mazzilli made the announcement Thursday.
"He's earned it," Mazzilli told the Baltimore Sun. "He deserves it, too, especially with what he did last year, how he carried himself."
