José Canseco Capas Jr., born on July 2, 1964, in Havana, Cuba, became one of the most talked-about figures in Major League Baseball during his career. He moved to the United States with his family when he was an infant, settling in Miami, Florida. Canseco's journey to the major leagues began when he was drafted by the Oakland Athletics in the 15th round of the 1982 MLB Draft.

Canseco made his major league debut with the Oakland Athletics on September 2, 1985. By the following year, he had secured his place as a regular in the Athletics' lineup. In 1986, he was named the American League Rookie of the Year, hitting 33 home runs and driving in 117 runs. His powerful hitting quickly made him a fan favorite and a feared opponent.

The 1988 season was a standout year for Canseco. He became the first player in Major League history to hit 40 home runs and steal 40 bases in a single season, a feat that earned him the American League Most Valuable Player award. This "40-40 club" achievement highlighted his rare combination of power and speed. That same year, Canseco helped lead the Athletics to the World Series, although they were defeated by the Los Angeles Dodgers.

Canseco's tenure with the Athletics continued to be productive. In 1989, he played a crucial role in helping the team win the World Series, defeating the San Francisco Giants in a series that was famously interrupted by an earthquake. Despite injuries limiting his play in the early 1990s, Canseco remained a potent offensive force.

In 1992, Canseco was traded to the Texas Rangers, a move that surprised many fans and analysts. His time with the Rangers was marked by both impressive performances and controversies. In 1993, he was involved in a memorable incident where a fly ball bounced off his head and over the fence for a home run. Later that year, he made an ill-fated pitching appearance that resulted in an arm injury.

Canseco's career continued with stints at several other teams, including the Boston Red Sox, Toronto Blue Jays, and Tampa Bay Devil Rays. In 1998, while playing for the Blue Jays, he once again reached the 40-home run mark, demonstrating his enduring power at the plate.

In 2000, Canseco joined the New York Yankees, where he was part of the team that won the World Series, although his role was more limited compared to his earlier years. He finished his playing career with the Chicago White Sox in 2001.

Throughout his career, Canseco was a six-time All-Star and won four Silver Slugger Awards. He hit a total of 462 home runs and had 1,407 RBIs. However, his career was also marred by controversies, particularly regarding his admission of steroid use, which he detailed in his 2005 book "Juiced: Wild Times, Rampant 'Roids, Smash Hits & How Baseball Got Big." This book sparked widespread debate and led to increased scrutiny of performance-enhancing drugs in baseball.

José Canseco's career was a blend of remarkable achievements and contentious moments.
