Nuno was recalled from Triple-A Norfolk on Friday, Roch Kubatko of MASN Sports reports.
The left-hander spent the past month in the minors, accruing a 3.86 ERA and an 11.6 K/9 in 14 innings out of the Tides' bullpen. Nuno will likely offer middle relief help in Baltimore, although his previous struggles in the big leagues certainly don't make him an attractive fantasy option despite his nice strikeout totals.
