Rienzo was optioned to Triple-A New Orleans following Friday's game against the Rockies, Manny Navarro of the Miami Herald reports. With Mat Latos set to return from the disabled list Saturday, Brad Hand was set to join the bullpen as a long man, leaving the Marlins with no need to continue carrying Rienzo. The 26-year-old Brazilian made three relief appearances during his stint with the big club, giving up two runs on four hits and four walks over seven innings.
