Vazquez is out of the lineup for Sunday's game against the White Sox, Christopher Smith of MassLive.com reports.
Vazquez sits for the second time this weekend while Sandy Leon receives a turn behind the plate. The 28-year-old Vazquez still has a stranglehold on the top spot on the depth chart, but he won't be asked to handle the overwhelming share of starts like many No. 1 backstops around the league.
