Despite winning the American League pennant in 1902, the Athletics did not retain Castro. He played in the Pacific Coast League and the South Atlantic League, and even managed the Augusta Tourists for a few seasons. Late in his life, he moved back to New York and lived with his wife until he died at age 64.
Through 1910, all the documents surrounding Castro's life—Manhattan College records, newspaper articles from his playing days and the form he filled out for the 1910 census—describe Castro as being from Colombia. There was no reason to question that fact until 2001, when Beverage came across Castro's file at the Association of Professional Ball Players of America. Castro, who was apparently quite poor at the end of his life, had joined the association in 1937 and received financial assistance from the organization in the final year of his life, Beverage says. Castro's file lists his place of birth as New York City, and that—coupled with his death certificate and his 1930 census form, both of which list Castro's birthplace as New York—was enough to convince SABR's biographical committee to change his birthplace to New York.
No one knows why the forms say different things. Garcia found a ship's log that lists a Louis Castro as an American citizen, so it could be that Castro learned at some point during his life that he was actually born in New York. Or perhaps a middle-aged Castro feared getting deported, or thought he could get more financial assistance by being an American citizen. Whatever the reason, that little switch of information has caused baseball researchers much angst over the years.
Martinez, however, thinks he has it figured out. Recently, he found a list of passengers from the S.S. Colon, which arrived in New York in 1885. The list includes an eight-year-old boy, Master Louis Castro, as well as another Castro with the first initial "N," which might have referred to Nestor, Louis' father. Though Major League Baseball still lists Castro as being from New York, the ship's log was enough to convince Martinez and Landino that Castro was indeed the first foreign-born Hispanic to play in the major leagues. Even the skeptical Beverage now says, "My thinking has sort of changed. It’s conceivable that he was born in New York, but I’m beginning to think that he was born in Colombia."
Even if Castro was indeed Colombian, many say the identity of the first Hispanic ballplayer is still up for debate. Some say that Esteban Bellan, a native-born Cuban who played with the Troy Haymakers of the National Association in 1871, should be acknowledged as the first Hispanic to play professional baseball. Jim Graham, director of the Baseball Hall of Fame library agrees: "Bellan did play at the highest level of the game that existed in 1871, so we usually throw the nod in his direction." Others point to Vincent Irwin "Sandy" Nava, who was born in San Francisco but described his mother as being from Mexico. Nava played for the Providence Grays in the 1880s.
But the Elias Sports Bureau does not consider the National Association an official major league, which would eliminate Bellan, and Martinez argues that Nava's birthplace rules him out as well.
Using that logic, Castro would indeed be the first of many Hispanics to play in the major leagues. And even though he might not have been harassed the way Jackie Robinson was in his day, he did open doors—perhaps even for Robinson. Branch Rickey, who eventually signed Robinson to the Dodgers, saw Castro as an early example of integration in the Major Leagues, Burgos says.
"I think it’s a big part of what you saw teams do throughout the 1930s and early '40s," Burgos says. "They continued to push the limits of what was the exclusionary point along the color line."

Corrections appended, October 19, 2007: Originally this article contained several errors about Napoleon Lajoie's time with the Philadelphia Athletics. Lajoie spent five years with the Philadelphia team in the National League before joining the American League's Athletics in 1901. The article said Castro was sent down to the farm system in 1902; he was not retained by the team. The article also said a list of passengers from the S.S. Colon included "Nestor Castro." It actually included "N. Castro," which could have been Nestor, Louis Castro's father.
