Ryne Sandberg is throwing third base up for competition between Phillies prospects Cody Asche and Maikel Franco, the Philadelphia Daily News has reported.
Asche is the only one with major league experience. He batted .233 with five home runs and 22 RBI in 162 at-bats at the end of last season. He remains the favorite to land the starting job.
The 21-year-old Franco has not played above Double-A, but he was highly productive at Reading in 2013, batting .339 with 15 home runs and 51 RBI in just 277 at-bats. He blasted 36 home runs in Class A and AA combined.
