"So many things happened in one year," said Villanueva. "It was definitely a breakthrough. It was a chance to show that I belong here. No matter what happens now, I'm here to make the team. That's my No. 1 goal."But the Brewers have five experienced starters expected to fill the starting rotation: Dave Bush, Chris Capuano, Ben Sheets, Jeff Suppan and Claudio Vargas. Villanueva says he is more than willing to take a bullpen role. "You have to be realistic -- we both know exactly what's going on," Villanueva said. "But at the same time, you have to go out there and compete. Like last year, I knew I had no chance of making the team, but I still treated every outing like I was competing for it." So did Jackson, who was acquired along with Bush and outfielder Gabe Gross in a 2005 Winter Meetings trade that sent popular first baseman Lyle Overbay to the Blue Jays. Jackson was a supplemental first-round draft pick of the Jays in 2004, and he was rated Toronto's eighth-best prospect by Baseball America before the trade. Jackson started 2006 at Nashville, where he went 2-2 with a 3.00 ERA before joining the Brewers on June 3. At that time, he had pitched only 41 games as a pro. "There was never a moment where I was intimidated, where I felt like those guys were that much better than me," Jackson said. "I caught a hot team when I faced the Twins [on July 2], and that was my worst outing. But for the most part, I kept us in games, and I'm proud of that. That's our job." Jackson said he worked with some of his college coaches on a few minor adjustments during the offseason, related to getting his front foot down more quickly and not "flying off" during his delivery. He'll continue to work this spring on his changeup, and he tweaked his slider during the offseason so it has more depth and downward break. Before, Jackson's slider was too similar to his cut fastball. "The average fan is still going to see how Zach still goes over his head [during his delivery] and has that quirky motion," Jackson said. "My changes have been a little more specific. I want to limit the walks and all the other little things that add up. "I just want to be ready in case something comes up and there is an opportunity. Our rotation is pretty much set, so I just have to take care of the things I can control, and that's getting prepared." Villanueva is not working on any new pitches this spring ("Thank God my changeup never leaves me," he says) but he does have a bit of a new look. He dropped about 15 pounds during offseason workouts in the Dominican Republic with Brewers closer Francisco Cordero. By the end of last year, probably the result of clubhouse spreads and 2 a.m. hotel room service, Villanueva figures, he had bulked up to 233 pounds. "I felt good, but I saw some of the games and I didn't look good," he said. "I looked overweight." Where they go in 2007 remains to be seen, but it's possible that Jackson and Villanueva will both see some action in Milwaukee. "It helps to have guys you can talk to, to get things off your chest when you need to," Villanueva said. "We're really looking forward to this year, even more than last year."
