Patino was optioned to Triple-A Durham following Sunday's loss to the Yankees, Marc Topkin of the Tampa Bay Times reports.
Patino made two turns through the Rays' rotation over the last week, but he'll head back to the minors after he gave up nine runs on five hits and four walks while failing to strike out a batter in 1.1 innings Sunday. The right-hander has posted a 4.50 ERA and 1.32 WHIP in 34 innings over nine Triple-A starts and could be an option to rejoin the major-league club if the Rays need a spot starter down the stretch.
