Posted: Updated:

TUCSON -- Edwin Jackson struggled against San Francisco on Sunday, allowing four runs on five hits over 4-and-two-thirds innings of the Arizona Diamondbacks' 4-3 loss to the Giants.

Jackson issued four walks, struck out none and gave up a three-run home run to John Bowker in the first inning.

Right-hander Kevin Pucetas allowed one run -- his first of the spring -- in five innings. Pucetas had pitched nine scoreless innings before Sunday.

Arizona's Conor Jackson led off the bottom of the first with a single, stole second, advanced on a single and scored on a double play.
