Lugo was optioned to Triple-A Las Vegas on Saturday.
Lugo's first stint in the majors lasted only two days as he will head back to Las Vegas with Juan Lagares coming off the DL. Lugo tossed two scoreless innings Friday against the Cubs in his major league debut. The 26-year-old will now look to turn his season around in Las Vegas, as he's collected a 6.55 ERA and 1.69 WHIP over 68.2 innings with the Mets' minor league affiliate.
