McCullers will start Game 4 of the ALDS against the White Sox on Tuesday, Brian McTaggart of MLB.com reports.
Jose Urquidy initially lined up to start Game 4, but McCullers will take the mound on normal rest after the contest was pushed from Monday to Tuesday due to inclement weather. The right-hander started the series opener and allowed four hits and no walks while striking out four in 6.2 scoreless innings to earn the win.
