Pete Alonso

Pete Alonso (born December 7, 1994, Tampa, Florida, U.S.) is a slugging first baseman for the New York Mets who holds the record for most home runs by a rookie (53) and who is also famous for his prodigious “moon shots.” He is called the “Polar Bear” for his big body, his power, and his fun-loving personality.

Early life and ancestry

Alonso was born to Michelle and Peter Matthew Alonso in Tampa, Florida. His grandfather Peter Conrad Alonso fled Spain as a teenager during the Spanish Civil War and settled in the New York City borough of Queens, the home of the Mets. “It all comes around full circle,” the Mets’ Alonso told Newsday in 2019. His grandfather got to see him play for the Mets’ minor-league team, the Brooklyn Cyclones, but died at the age of 95, just a few months before Alonso made his major-league debut, in 2019.

Growing up in Tampa, Alonso played for the “Yankees” Little League team with the grandson of New York Yankees owner George Steinbrenner. When the Little League Yankees won their league championship in 2002, Alonso got a letter from the big-league Yankees manager, Joe Torre, who praised the then seven-year-old for upholding the team’s reputation. Alonso hung the framed letter on his bedroom wall.

After initially attending Jesuit High School in Tampa, Alonso transferred to Plant High School, which has produced several professional baseball players. When Alonso, who graduated in 2013, was not chosen in the Major League Baseball (MLB) draft, it only increased his motivation. He went on to play baseball at the University of Florida, where he was known for both his intense work ethic on the field and his laid-back ways off it. On one hand, he spent so much time in the batting cage that the joke among his coaches was that he slept there; on the other hand, he skateboarded around campus, starting a trend among his Gator teammates.

Alonso later said that he did not start to truly find himself until 2014, when at age 19 he played for the Madison (Wisconsin) Mallards of the Northwoods League, a collegiate summer baseball league. “My only goal that summer [was] to prove to myself that I’m a badass and that I can rake,” he recalled in a column he wrote for The Sporting News in 2018, about a year before his major-league debut. After that summer, Alonso wrote, “I realized what I needed to start doing to be successful; play with your instincts [and] let ’em hang.”

A historic beginning

In 2016 the Mets drafted Alonso in the second round, and, after three years in the minor leagues, the team brought him to spring training with a chance to make the big-league team. Alonso forced his way onto the 2019 roster with an outstanding performance in the spring exhibition games, batting .352, with four home runs. Then he put together one of the most memorable rookie seasons in baseball history. By the All-Star break, he had hit 30 home runs, and he edged out fellow rookie Vladimir Guerrero, Jr., to win the All-Star Game’s Home Run Derby by belting 23 dingers compared with 22 for Guerrero. Alonso pledged 5 percent of his $1 million prize for winning the derby to the Wounded Warrior Project and another 5 percent to the Tunnel to Towers Foundation. Later in the 2019 season, he wore cleats to honor the victims of the September 11 attacks and ordered pairs for his teammates.

Alonso quickly became a fan favorite. As The New York Times wrote in a June 2019 profile, “In the wake of David Wright’s retirement and Yoenis Cespedes’s rehabilitations, [Alonso] has filled the offensive void with a potent bat and boyish exuberance.” Alonso was popular among his teammates for his infectious personality. But he was also serious about his craft, and in his locker he kept a composition book in which he entered observations about his performance following games.

On September 28, 2019, in the second-to-last game of the season, Alonso hit his 53rd home run of the season, against the Atlanta Braves at Citi Field, the Mets’ home ballpark, breaking Yankee Aaron Judge’s MLB rookie record for home runs. After Alonso tied him the night before, Judge told The New York Times, “There’s no better individual to represent not only the Mets but the city of New York. He’s going to do a lot of special things over his long career, so I’m excited for him. It’s just the beginning for him, and it’s the first of many records he’s going to break.”

Alonso was a near-unanimous choice for National League (NL) Rookie of the Year, receiving 29 first-place votes out of 30 cast, and he finished seventh in the NL Most Valuable Player Award tally. In addition to his league-leading 53 home runs, he drove in 120 runs—the most for a rookie since 2001, when Albert Pujols of the St. Louis Cardinals had 130 runs batted in (RBIs).

Alonso has not been able to match the power of his rookie season, but he has still put up big numbers. Following the COVID-19-shortened 2020 season, he has averaged more than 40 homers a year, including 46 in 2023. But that season, he batted a career low .217—a drop-off of more than 50 points from his batting average the previous season—which included the longest slump of his big-league career.
