The Cubs will consider trading right-hander Matt Garza in an effort to add depth to their starting rotation. "I don't think we are done," Cubs president Theo Epstein said. "I do think we still need to build more depth on the starting pitching front, both in the big leagues and minor leagues. "But it doesn't happen overnight. You have to make sacrifices. Just like moving Sean Marshall, who was certainly an asset for the 2012 club." Garza led the Cubs with a 3.32 ERA and 197 strikeouts and tied for the team lead with 10 wins in 2011. "Matt Garza is the type of pitcher you want to build around," Epstein said. "He's a proven top-of-the-rotation guy, a proven performer in the playoffs. I think last year he had his best season, all things being equal. "It's hard to find top-of-the-rotation guys, so if you have them, and if there's a way to keep them around, that's always compelling for the club. With that said, we've been honest. We are in a mode where we have to listen on everybody. And if there's a way to improve the long-term outlook for this club in a significant manner, we can't look past opportunities."
