The Chicago Cubs showed up for their exhibition game against Colorado about an hour later than expected after their bus broke down on the highway because of engine trouble.

The Cubs chose to skip batting practice when they got to Hi Corbett Field in Tucson on Monday. They decided to just stretch instead.

The Cubs were making a two-hour drive south when the bus broke down. Starting pitcher Carlos Zambrano was lucky -- his cousin was following in a car, so they drove with catcher Koyie Hill to the park.

Cubs manager Lou Piniella wasn't with the team on the bus. He was driving separately with pitching coach Larry Rothschild.
