Perez was recalled from the Astros' taxi squad Sunday, Jake Kaplan of The Athletic reports.
With Lance McCullers (neck) landing on the IL, Perez was summoned back to the big-league club a day after he was sent packing. The lefty has made four appearances out of the Astros' bullpen this season, allowing one run on five hits and four walks while striking out six over 4.1 innings.
