TUCSON, Ariz. (AP) - Edwin Jackson struggled against San Francisco on Sunday, allowing four runs on five hits over 4 2-3 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, competing for the fifth spot in the Giants' starting rotation, 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.
