SCOTTSDALE, Ariz. -- Although not yet official, the Giants' Opening Day roster appears to be close to finalized, hinted manager Bruce Bochy on Wednesday.
The biggest issue is Travis Ishikawa's sore lower back. The first baseman/outfielder hasn't played since leaving Sunday's game, and the idea of Ishikawa opening the season on the 15-day disabled list is a possibility, Bochy said.
Discussions will take place Wednesday on the Giants' flight back to San Francisco, but should Ishikawa open the season on the DL, the Giants likely will keep all three of their backup infield candidates -- Ehire Adrianza, Joaquin Arias and Matt Duffy -- with Brandon Belt serving as the fifth outfielder in case of an emergency.
Belt started in the outfield Wednesday for the first time this spring.
"We wanted to check this box off," said Bochy, noting Belt playing the outfield is once again an option when Buster Posey plays first base.
If Ishikawa miraculously recovers in time, Duffy may still have solidified his place on the roster on Wednesday with another standout game. He went 1-for-3, with his lone hit a two-run homer crushed to right-center field off reigning American League Cy Young Award Corey Kluber.
Duffy finishes Cactus League action with a .382 average and three home runs, and also spent Wednesday morning working with coaches on his defense at third on a day when there was no official pregame workout.
"This kid, we've thrown everything at him," Bochy said. "He's just had a great spring. Just love his at-bats and he fights up there. He's doing what we've talked about you hope young guys do and really forced the issue."
The final roster spot is still between Jean Machi and George Kontos.
