In five years with the Washington [D.C.] Senators, Marrero compiled a 39-40 record, with 297 strikeouts. He was named to the American League All Star team in 1951. Cut by the Senators four years afterward, he went back to Cuba to play for the Havana Sugar Kings and stop working in 1957. He was privileged by the Cuban government as a Hero of the Republic of Cuba in 1999. After the age of 100, Marrero was sightless and limited to a wheelchair, with hearing and speech complicatedness. Reporters state he spent much of that time listening to Cuban baseball on the radio and frequently chewing on a cigar and forever prepared to recall about his Major League career.
“Putting on that uniform always made me feel bigger, more powerful,” Marrero said in 2013, on his 102nd birthday. Marrero became the oldest living ex-Major Leaguer in February 2011 after the death of previous Brooklyn Dodgers infielder Tony Malnoisky. The difference now goes to Mike Sandlock, a 98-year-old former catcher who played 195 games with the Braves, Dodgers and Pirates. Sandlock was born Oct. 17, 1915. In current years, Marrero established $30,000 from Major League Baseball under a disbursement program for players who were active between 1947 and 1979. The funds had been postponed for two years by difficulty related to the U.S. economic and financial embargo on Cuba.
