TEMPE, Ariz. -- At the current rate, whoever wins the Giants' backup catching job will do so by default.

Eliezer Alfonzo is batting .075 (3-for-40). Guillermo Rodriguez is hitting .118 (2-for-17). Each committed a passed ball in the Giants' 8-1 exhibition loss Thursday to the Los Angeles Angels.

And to think that, at the beginning of Spring Training, manager Bruce Bochy actually was considering opening the season with a contingent of three catchers, led by regular Bengie Molina.

"We need to have somebody step up and take this job," Bochy said. "It's been a tough spot for us here. Neither one of them is on track offensively or catching all that great right now."

Alfonzo appeared to have an edge on Rodriguez as camp began. Alfonzo earned Most Valuable Player honors in the Venezuelan Winter League during the offseason by hitting 15 home runs with 47 RBIs in 53 games for Caribes. He added seven homers and 16 RBIs in 14 playoff games.

But Alfonzo began the exhibition season 0-for-17 before collecting his first hit, a homer. "He's a better hitter than he's shown," Bochy said.
