Zambrano to start workout program this week

PHOENIX (AP) — Carlos Zambrano is expected to resume working sometime this week, though the Chicago Cubs aren't sure when he'll return to the team.

The hot-tempered right-hander was placed on the restricted list after a June 25 tirade in the dugout led to a verbal confrontation with teammate Derrek Lee. Last week, Zambrano was scheduled to undergo a treatment program agreed upon by doctors from the Players' Association and Major League Baseball.

Cubs manager Lou Piniella said the three-time All Star would likely start pitching this week, though he wasn't sure where. Piniella said the team would put together a program to get him ready.
