The Diamondbacks released Rivero last month. Rivero was most recently playing for Triple-A Reno. The third baseman is expected to find his next job playing overseas.
Rivero re-signed with the Diamondbacks on a minor league contract, Matt Eddy of Baseball America reports. The 28-year-old slashed .277/.316/.484 with 19 home runs in 124 games with Arizona's Triple-A affiliate in 2016. He briefly made it to the majors in 2014 with Boston, but only lasted four games. This is primarily a signing to provide depth at the hot corner.
Rivero signed with the Diamondbacks on Monday, Matt Eddy of Baseball America reports. Rivero split the 2015 season between a pair of club's Triple-A rosters, though he slashed just a combined .254/.299/.355. He'll likely start the season in the minors and serve as infield depth.
The Red Sox have purchaed infielder Carlos Rivero from the Mariners, the Tacoma News-Tribune has reported. He will be assigmed to Triple-A Pawtucket. The 27-year-old Rivero, who has four hits in seven at-bats in the majors, owns a mediocre .256/.296/.372 slash line at Triple-A Tacoma this season.
The Mariners have optioned pitcher Roenis Elias to Triple-A Tacoma, the team announced Sunday. An earlier report Sunday said that the team was considering going with a six-man rotation, and it's possible that could still come to pass, with Elias making frequent trips to and from the active roster. For now, it appears Taijuan Walker will serve as the team's fifth starter. The Mariners also reassigned the following eight players to minor-league camp Sunday: catcher John Baker, outfielder Endy Chavez, infielders Shawn O'Malley and Carlos Rivero and pitchers Mark Lowe, Jordan Pries, Kevin Correia and Joe Saunders .
