Bellinger had started every other game this season against right-handed pitchers. Roberts framed the decision to sit Bellinger as a way for the 2017 National League rookie of the year to decompress in the midst of a horrific slump, with Bellinger expected back in the lineup on Tuesday in Pittsburgh.
Bellinger has hit .171 with a .632 on-base plus slugging percentage since May 1. He has struck out in 28% of his plate appearances.
