MILWAUKEE (AP) -- Brewers pitcher Ben Sheets threw a 35-pitch bullpen session yesterday.
But manager Ned Yost says Sheets still had some discomfort in his strained left hamstring.
The team has not decided whether Sheets will start Friday night against San Diego.
Yost says injured catcher Johnny Estrada could be available for pinch-hitting.
That's despite the torn ligament in his left knee that's expected to require surgery.
