Renato Rafael Núñez (born April 4, 1994) is a Venezuelan professional baseball third baseman for the Saraperos de Saltillo of the Mexican League.

He played the entire 2016 minor league season with the Triple-A Nashville Sounds, and was called up to the Athletics on September 12.

Nearing the end of the assignment and out of options, Nunez was placed on waivers and subsequently claimed by the Texas Rangers on April 15.

[10] After appearing in 13 games and batting .167/.244/.278 with two RBIs in 36 at-bats, he was designated for assignment by the Rangers when Rougned Odor was activated from the disabled list on May 11.

[12][13] His contract was selected two months later on July 20, and he made his Orioles debut as the starting third baseman in a ten-inning 8–7 loss to the Toronto Blue Jays at Rogers Centre that same night.

[14][15] His opportunity at becoming the regular third baseman was made possible by the fire sale trade of Manny Machado two days prior during the All-Star break.

The Orioles needed to create a spot on its 40-man roster to protect an additional minor-league prospect in preparation for the Rule 5 draft.

[21] On February 10, 2021, Núñez signed a minor league contract with the Detroit Tigers organization that included an invitation to Spring Training.

[23] Núñez had three days to accept his minor league assignment or opt out of his contract and become a free agent.

[31] On August 30, 2021, the Milwaukee Brewers signed Núñez to a minor league contract and assigned him to the Triple-A Nashville Sounds.

[33] On November 5, 2021, Núñez signed a one-year, $1.6 million contract with the Hokkaido Nippon-Ham Fighters of Nippon Professional Baseball.
