PEORIA, Ariz. (AP) Matt Kemp hit his first home run of the spring and singled against erratic Giants starter Jake Peavy in the San Diego Padres' 8-4 loss to San Francisco on Thursday night.

Kemp who entered hitting .222, finished 3 for 4. Jon Jay also homered off Peavy and added an RBI groundout.

Peavy allowed three runs and eight hits in four innings, working out of jams to prevent more damage. In 12 2/3 innings over four appearances, the 34-year-old right-hander has given up 27 hits and 14 runs.

Padres starter Andrew Cashner allowed five runs - two earned - on four hits with two walks and a hit batter in four innings. Jarrett Parker hit a solo homer in the first off Cashner, who entered having not allowed a run in five innings.

Brandon Belt doubled, bunted for a single and had a sacrifice fly for the Giants.
