Giants uncertain on Span, Crawford for series finale

Manager Bruce Bochy listed center fielder Denard Span as doubtful for Sunday’s series finale and shortstop Brandon Crawford as questionable.

A day after feeling soreness in his left quadriceps tumbling over first base, Span pinch hit in the sixth inning Saturday but couldn’t swing. He was asked to sacrifice but bunted into a fielder’s choice and was replaced by a pinch-runner, Jeff Samardzija.

Crawford bruised his left thumb on a swing Friday and didn’t start Saturday but entered defensively in the final inning and threw out Wilson Ramos to end the game. The bruise affects Crawford mostly when swinging.

If Span and Crawford miss Sunday’s game, they’d get an extra break with Monday’s off day.
