Braves' Braden Shewmake: Big-league debut Friday

Shewmake is starting at shortstop and batting ninth Friday against the Orioles.

Shewmake will enter the lineup after being called up from Triple-A Gwinnett on Friday, replacing Vaughn Grissom at shortstop. Grissom has struggled to a .190 average with seven strikeouts over his last six games, so he could slide into a timeshare with Shewmake if the latter performs well in his big-league debut.
