ANAHEIM -- Angels prospect Grant Green is expected to be called up from Triple-A Salt Lake before Friday's game as the corresponding move for reliever Yoslan Herrera getting optioned to Triple-A, according to a source.
With the move -- not official until Friday -- the Halos would go back to the standard 12 pitchers and 13 position players.
And Green is expected to get a fair share of playing time.
The 26-year-old right-handed hitter, acquired from the A's in exchange for Alberto Callaspo last July, was hitting .365/.412/.529 through his first 25 games in the Pacific Coast League, and he had started each of his last six games in left field.
Green becomes a right-handed-hitting option in left field, while also giving the Angels versatility at second and third base. He could take some at-bats away from struggling left-handed hitters J.B. Shuck (.156/.177/.247) and Raul Ibanez (.157/.231/.313).
