Khris Davis homered in his first appearance before the Oakland home crowd and the Athletics concluded the spring training schedule by beating the San Francisco Giants 4-1 Saturday. Davis connected against Matt Cain leading off the third, when the A's added on two more thanks to an assist from new Giants center fielder Denard Span. Span's two errors on one play trying to secure Jed Lowrie's deep flyball allowed Lowrie to round the bases for a 3-0 lead in the third.
