Ynoa was called up by the Braves on Tuesday.
Ynoa made a pair of relief appearances last season, allowing six runs over three innings of work. He hasn't proven himself at the Triple-A level yet, either, as he produced a 5.33 ERA in 72.2 innings for Gwinnett in 2019. He'll likely be limited to low-leverage work during his time on the big-league roster.
