Prior is on the disabled list to start a season for the second straight year thanks to a tender elbow. Cubs manager Dusty Baker said he wanted to give the right-hander some extra time to build up his endurance.
Wood was scheduled to start opening day but was scratched with a sore shoulder and a stiff back. He is now slated for the home opener on Friday.
Prior and Wood, who were All-Stars in 2003, combined for just 14 wins last year due to injuries.
“That was our strength in the first place actually. Going into last season more people talked about our pitching more than anything else,” said Baker, who is coming off guiding the Cubs to their first consecutive winning seasons in 30 years.
“Prior is going to win more than six and Wood is going to win more than eight.”
Known for his emotional antics and live arm, Zambrano tied future Hall of Famer Greg Maddux for the team lead with 16 wins last year.
“For me, mentally I’ll prepare like a normal game, like I was the No. 4 starter,” said Zambrano, who is coming off his first All-Star game appearance. “I just wanted to be focused for the game and not worry about anything else, not think about it being opening day.”
Zambrano was fourth in the NL with a 2.75 ERA in 2004 and ranked among the league leaders in strikeouts with 188 and batting average against (.225).
The Cubs were poised to make a run at the postseason last year as they were leading the NL wild-card race with less than two weeks to play, but they dropped seven of their final nine games. Despite trading Sammy Sosa to Baltimore and allowing Moises Alou to leave via free agency, the Cubs should be able to generate enough offense for their pitching staff.
“I like our attitude. I like our togetherness. I like our skill level, the combination of speed and power,” Baker said.
“We’ve got to get our starting pitching together. We have guys who have been there before in our bullpen. I just like the fact that guys are confident we can play.”
For the first time since their 1998 expansion season, someone other than Randy Johnson will start the opener for the Diamondbacks. Javier Vazquez, who came over in the trade that sent Johnson to the New York Yankees, will be looking to redeem himself following a rough second half last year.
The Diamondbacks, under new manager Bob Melvin, will be introducing a team that fans will hardly recognize following their dismal 111-loss season a year ago.
Only left-fielder Luis Gonzalez remains from last year’s opening day lineup. He will be joined by third baseman Troy Glaus and right fielder Shawn Green to form a potent 3-4-5 spot in the batting order.
“We’re not going to bang our chest and say we should be considered the favorite for the division title,” Melvin said. “But we like the team we have, and we think the more we play together, as the course of the season goes along, barring injuries, we feel like we’re a team that can get better.”
