CHICAGO -- He notched the first of 327 wins with the Cubs, and then his 300th. He struck out his first batter with the Cubs, and also his 3,000th. He won the first of four Cy Young Awards with the Cubs.

Greg Maddux's next start will be for the Los Angeles Dodgers. The 40-year-old pitcher was traded Monday to the National League West contenders for Gold Glove infielder Cesar Izturis, who is expected to take over at shortstop.

In another move, the Cubs dealt infielder Todd Walker to the San Diego Padres for 19-year-old Minor League pitcher Jose Ceda. Walker now is in first place in the West Division, and could be playing some third base for the Padres.

"It's always sad to see guys leave, especially quality guys," Cubs manager Dusty Baker said Monday. "You hate to see 'Walk' leave. Greg's probably the finest pro I've been around in years and years. He's a man, he comes to play, he comes to pitch, he comes to help."

Baker secretly was hoping the rumors wouldn't be true and Maddux would stay. Cubs general manager Jim Hendry said his talks with Dodgers general manager Ned Colletti had focused on high-level prospects and didn't include Izturis until 45 minutes before the trading deadline.

"Philosophically, I'd decided that if it wasn't a great package for us, that we would keep Greg," Hendry said. "To get Izturis, a Gold Glove winner, 26 years old, we have his rights through 2008. He was arguably, before his surgery, the best shortstop in the National League."

Izturis had Tommy John reconstruction surgery on his right elbow last September. This season, he was batting .252, with seven doubles and 12 RBIs in 32 games, and had played primarily at third. Ronny Cedeno is expected to move to second base for the Cubs.

"I admire the way he handled the situation, how hard he played and his willingness to move to third base, then second," Colletti said. "It speaks volumes for who he is, and I'm glad I could place him where he can do what he wants to do."

Even though Maddux's name was mentioned often in trade rumors leading up to the deadline, he said he didn't expect to be moved.

"I am very surprised, to be honest," he said. "It came down to the last minute. I'm excited to be going to L.A., but at the same time, I'm sad to leave Chicago. I'm going to try to be right with the new team and try to pitch well for them."

He was scheduled to start Thursday for the Cubs. Now, they'll have to fill that spot with either lefty Glendon Rusch or call up another rookie. The kids will miss having an extra coach in the dugout.

"They'll be as good as they want to be," Maddux said of the rookies. "It's up to them to take advantage of their talent and try to get the most out of it. It's up to them, really."

Switching teams was up to Maddux, too. He had a no-trade clause in his contract with the Cubs and had given the team a short list. The Dodgers, obviously, were on that list.

"I'm excited about going there," Maddux said. "At the same time, I'm not very excited about leaving Chicago. I started with them, I thought I was going to end with them. I look forward to going out West, a lot closer to home, and seeing more of my family."

The news wasn't really a shock to Walker, whose name had been mentioned in trade rumors since the offseason.

"I'm really going to miss this place," Walker said. "As we've seen, based on our struggles this year, these are some of the greatest fans in the world. There aren't too many ballparks where fans would support a team that's 20 games under .500."

Now, he's in first place in the NL West.

"It's really a situation where you have a bunch of mixed emotions," Walker said. "You leave a place where you're comfortable, and no question, this is the best place to play in baseball, but you go to a team that's in first place and has a chance to win the World Series. You can't complain about that. I hope I can help them."

On Saturday, in Maddux's last start for the Cubs, the crowd gave him a standing ovation as he left in the seventh. He tipped his cap.

"It's nice to win your last game here," Maddux said. "I had no idea I was going to be traded today. I knew it could happen, but I didn't know. I didn't want to speculate on anything. ... I wanted to let them know I appreciated it. Part of me will always be a Cub."

He was 9-11 with a 4.69 ERA in 22 starts this year with the Cubs, and has a career record of 327-200. Would he consider coming back to Chicago?

"Who knows? I've always loved Chicago, I've always loved playing here," he said. "We'll see what happens. I'm just looking forward to my next start, and hopefully I'll pitch well enough to win."
