NEW YORK - Alex Rodriguez admitted that he used performance-enhancing drugs from 2001 to 2003 Monday in an interview with ESPN.

Rodriguez said he used banned substances due to the pressures of being baseball?s highest-paid player during his time with the Texas Rangers.

"When I arrived in Texas in 2001, I felt an enormous amount of pressure. I felt like I had all the weight of the world on top of me and I needed to perform, and perform at a high level every day," Rodriguez said.

The Yankees third baseman admitted his steroid use two days after Sports Illustrated reported he tested positive in 2003 during a confidential survey testing held by Major League Baseball to determine the prevalence of performance-enhancing drug use in the sport. According to Sports Illustrated?s report, Rodriguez is one of 104 players who tested positive. The results of the test were supposed to remain anonymous.
