According to first-hand accounts, Sheets threw two simulated innings off the mound in a side session.
The Louisiana native threw all of his pitches, topping out at 90 mph with the fastball. Sheets threw 20 pitches in each simulated inning, before fading and stopping his throwing in a third inning.
According to sources, the right-hander was throwing free and easy. Sheets will throw again next week, and the Cubs will send a scout to watch. Other teams also will be invited.
The Cubs never have tried to negotiated a contract with Sheets' agent Casey Close. Cubs general manager Jim Hendry did talk to Close at the winter meetings about a number of different players and subjects.
Sheets was said to be asking $7 million in December. That figure probably has dropped, but no one is sure how low it will fall.
Meanwhile, a report on FOXsports.com that the Cubs have been looking at former Cardinal pitcher Mark Mulder is inaccurate. The report stated the Cubs and Cards have been monitoring Mulder's workouts. According to a Cubs source, they haven't watched Mulder, nor have they talked to his agent.
