Antonacci is out of the lineup for Wednesday's game against Atlanta.
Derek Hill will receive the starting nod in left field over the left-handed-hitting Antonacci, who will hit the bench while southpaw Chris Sale toes the rubber for Atlanta. Since being called up from Triple-A Charlotte on April 15, Antonacci has gone just 3-for-33 with a 1:10 BB:K in 40 plate appearances versus lefties.
