Carlos Luis Rivero Milán (born May 20, 1988) is a Venezuelan professional baseball third baseman who is a free agent.

Rivero was originally signed by the Cleveland Indians as an international free agent in 2005, and played for them for five minor league seasons (2006–2010) before joining the Philadelphia Phillies (2011) and Washington Nationals (2012–2013) organizations.

He also was rated twice by Baseball America as having the best infield arm in the Indians organization in the 2008 and 2009 seasons, before being named the best defensive third baseman in the International League in 2012 while playing for Washington affiliate the Syracuse Chiefs.

[5] Previously, he was named the 2007 South Atlantic League Mid-Season All-Star while playing for the Lake County Captains, also a Cleveland affiliate.

[1] Not long after signing him, the Red Sox assigned Rivero to Double A Portland Sea Dogs to start the 2014 season.

In addition, Rivero drove in five runs and scored six times, while compiling three extra-base hits, as his efforts helped Pawtucket conclude a 5-2 stretch.

[2] After nine seasons in professional baseball, Rivero became a major leaguer when the Red Sox purchased his contract from Pawtucket on August 25, 2014 after placing shortstop Xander Bogaerts on the seven-day concussion disabled list.

[8] On August 9, 2015, Rivero was traded back to the Boston Red Sox for cash and assigned to Triple-A Pawtucket.

[13] On December 12, 2022, Rivero was traded to the Tecolotes de los Dos Laredos in exchange for Wilfredo Tovar.

Castillo, Rivero, and Valbuena were all members of Venezuelan winter team Cardenales de Lara, and had played a game the day of the accident.
