Ronald Enmanuel Guzmán Cepeda (born October 20, 1994) is a Dominican professional baseball first baseman and pitcher who is a free agent.

[8] Guzmán spent the 2017 season with the Triple–A Round Rock Express, posting a stat line of .298/.372/.434/.806 with 12 home runs and 62 RBIs.

After the 2017 season, the Rangers organization named him their 2017 Tom Grieve Player of the Year (minor league).

[9] Guzmán returned to the Round Rock Express to start the 2018 season, playing in 5 games with them before being recalled to the major leagues for the first time.

[10] He hit his first major league home run on April 14, 2018, to tie a game against the Houston Astros in the top of the eighth inning.

[14] After slashing an impressive .316/.409/.518/.927 batting line at Nashville, he was called up on September 1 to become the Rangers' everyday first baseman.

On April 12, 2021, his first career start in left field and the outfield, Guzmán tore the meniscus in his right knee and was placed on the 10-day injured list the next day.

[26] On March 14, it was announced that Guzmán would miss 6-8 weeks after suffering a pronator strain in his left forearm.

[30] In 8 games split between the rookie–level Florida Complex League Orioles and High–A Aberdeen IronBirds, he struggled to a 13.50 ERA with 11 strikeouts and one save across 7+1⁄3 innings pitched.

Guzman did not face any charges from the incident, as the police determined that the motorcycle driver had failed to stop at an intersection.
