Rafaela isn't in the lineup for Saturday's game versus St. Louis, Ian Browne of MLB.com reports.
Rafaela has gone just 3-for-18 with two RBI and two runs scored across his last five games. The Red Sox will give him a day to collect himself Saturday; meanwhile, Jarren Duran will shift to center field, moving Kristian Campbell into left and opening second base for David Hamilton.
