David Baas bounced a couple of snaps during team drills and knows that's not going to cut it. Afterward, he and 49ers quarterback Alex Smith stayed on the field to do more work and find their timing.
Baas is determined to win the starting job at center for San Francisco to replace the injured Eric Heitmann -- and Baas sure seems to be the front-runner after getting all the repetitions with the first team Tuesday morning.
Heitmann broke his left leg Monday and is expected to miss up to two months, a big blow for a unit that is determined to establish some continuity in 2010.
The Niners' new-look offensive line, featuring rookie first-round picks Anthony Davis and Mike Iupati, will get its first real test in an exhibition opener Sunday at Indianapolis.
