Richards is starting Game 2 of Thursday's doubleheader against the Orioles, Marc Topkin of the Tampa Bay Times reports.
Richards was recalled from the team's alternate training site earlier in the day, and as expected, the right-hander will toe the rubber for Game 2. He's appeared in eight games this season and owns a 5.34 ERA and 1.67 WHIP with 23 punchouts over 28.2 innings.
