Manzardo was recalled from Triple-A Columbus and is batting sixth as the designated hitter against the Pirates on Sunday, Zack Meisel of The Athletic reports.
The 24-year-old is one of the organization's top prospects and will immediately enter the lineup as he joins the big club for the stretch run. Manzardo posted a .207/.241/.329 slash line with a 26.4 percent strikeout rate over 30 games in his first taste of the big leagues earlier this season, and he isn't guaranteed to have a regular place in the lineup.
