Justin Broussard, who hit .310 with 11 RBIs and 13 extra-base hits in 116 at-bats as a freshman infielder, is academically ineligible, Altobelli said.
Altobelli said four outfielders have all distinguished themselves, though he will likely open Friday with sophomore returner Zack Nehrir in left field, freshman Cody Bruder in center and freshman Austin Saenz, who redshirted at Cal State Fullerton last season, in right.
Nehrir hit .209 with four RBIS in 43 at-bats as a freshman last season, while Bruder prepped at Santiago High in Corona.
Freshman Christian Salina is also in the outfield mix after hitting .338 with three homers and 21 RBIs as a senior at Capistrano Valley High in 2012.
Saenz hit .495 with 51 hits, three homers and 25 RBIs as a senior at Mission Viejo High in 2011. He also had 12 doubles and a slugged .699.
There's a four-player logjam behind the plate, where Wichita State bounce-back Tucker Chadd is among three freshmen contending for playing time.
Sophomore Steve Pollakov is a transfer from Rochester University where he hit .179 with six RBIs in 39 at-bats last season.
Freshmen Jake Toll-McKillop and Christian Fillingame are also in the catching mix. Toll-McKillop hit .478 in 67 at-bats with 17 RBIs last season at Terra Linda High in San Rafael.
Altobelli said infield backups include freshman Greg Espinosa (shortstop), freshmen Cooper Michelson and Taylor Grace (second base), as well as freshman Chris Iriart and Hill (first base, designated hitter).
Espinosa hit .400 in 90 at-bats last season at Yucaipa High. He had 10 RBIs, 10 stolen bases and 10 doubles.
