Hanser Joel Alberto Peña (born October 17, 1992) is a Dominican professional baseball infielder for the Piratas de Campeche of the Mexican League.

He has previously played in Major League Baseball (MLB) for the Texas Rangers, Baltimore Orioles, Kansas City Royals, Los Angeles Dodgers, and Chicago White Sox.

[2] The Rangers promoted Alberto to the major leagues on May 28, 2015; he made his debut the next day against the Boston Red Sox.

[7] A few hours later, the Orioles claimed him off waivers,[8] but on February 19, the team designated him for assignment to make room for Josh Osich.

[9] Three days later, on February 22, he was claimed by the San Francisco Giants,[10] but after only a week with the team, he rejoined the Orioles on March 1.

[11] Alberto was pressed into service as a relief pitcher in the ninth inning of a 15–3 loss to the New York Yankees at Camden Yards on April 7, 2019.

[12] He joined teammates Renato Núñez and Anthony Santander as the third Oriole within a three-week span to achieve his own first-ever five-hit game in a 14–2 win over the Kansas City Royals at Kauffman Stadium on August 30, 2019.

[13] This occurred within a calendar month for the first time since Wally Moses, Frankie Hayes and Lou Finney did it with the Philadelphia Athletics in July 1936.

[28] On April 3, Alberto made his first pitching appearance of the season in a blowout loss against the San Francisco Giants, and recorded a strikeout of catcher Roberto Pérez.
