Rivera signed with the Rangers as a non-roster invitee Friday. Rivera hit a poor .183/.258/.217 in 34 games for the Marlins last season. That translates to a 33 wRC+, though that's actually stronger than his career 28 wRC+ over parts of five seasons.
Rivera was outrighted to Triple-A New Orleans on Thursday, Andre Fernandez of The Athletic reports. Rivera was designated for assignment by the Marlins on Tuesday, but after failing to draw interest while on waivers, he'll head to Triple-A.
Rivera was designated for assignment by Miami on Tuesday, Jordan McPherson of the Miami Herald reports. Rivera will be subjected to waivers after hitting just .183 with three RBI over 34 games this season with the Marlins. Hector Noesi was promoted to the big leagues in a corresponding move.
Rivera went 1-for-3 in Monday's loss to the White Sox. With Miguel Rojas (shoulder) and JT Riddle (forearm) both sidelined, Rivera is all the Marlins have left at shortstop, and the 27-year-old has gone 1-for-7 while starting the last two games. Rojas may not be out for long, but until he's cleared to return, Rivera and his .478 career OPS will remain in the lineup.
Rivera will start at third base and bat seventh Sunday against the Braves, Joe Frisaro of MLB.com reports. Rivera will draw a second straight start as the Marlins wrap up their series in Atlanta, but he's done little to make a case for receiving regular action once the second half begins. Since being recalled from Triple-A New Orleans on June 14, Rivera has gone 5-for-34 with 13 strikeouts.
