Arcia is in line to open the season as Atlanta's starting shortstop, David O'Brien of The Athletic reports.
Barring an addition at the position via trade in the days leading up to Opening Day, Arcia has won the shortstop gig over Vaughn Grissom and Braden Shewmake, both of whom were optioned to Triple-A Gwinnett on Monday. Arcia received the appointment atop the depth chart despite mediocre results at the plate in Grapefruit League play (.247/.367/.360 slash line over 30 plate appearances), but he impressed with his glove. Shewmake and Grissom both have a great chance of taking the job from Arcia if the 28-year-old struggles once the season gets underway.
