Pedro was born on July 26, 1938 in Havana, Cuba. He grew up alongside two brothers and one sister. When he was a young boy, his mother and father noticed his natural ability to play baseball. They were very supportive of Pedro's interests and encouraged him to play. His dad, while having established himself as a professional boxer, shared great wisdom with the younger Sierra. Pedro learned to focus on the task at hand and to jump on opportunity when it presented itself. He had trained hard to develop the mental discipline and the physical stamina that would give him an edge in competition.

In 1954, Pedro, at the age of 16, was signed to his first baseball contract with the Indianapolis Clowns of the Negro Leagues by a scout known to him as Sanchez. He completed the `54 Season with the Clowns, and returned to Cuba to play winter ball. In the spring of 1955, Pedro made the trip to the States again, this time to join the line-up of the Detroit Stars. The well-respected Ed Steele managed the Stars at this time. He was well respected and proved to be a fine educator as well as an intense manager.

Pedro went to work on the mound for the Stars. He was selected to toss in the East-West All-Star Game played in Chicago's own Comiskey Park, in each of the 4 years he played there. As the `59 season rapidly approached, Pedro was picked up by scout Joe Cambria and on his way to try-out for the Washington Senators. Upon arriving, he found the opportunity had passed - the team roster complete. So Pedro spent the `59 season on fields of the Lakeshore Virginia Rookie League.

Later that same year Pedro got a call from Uncle Sam. He had been drafted by the US Army and was assigned to the serve in the infantry at Fort Hood, Texas. Pedro quickly learned of the unit's baseball team, the Ft. Hood Tankers. He was soon on the roster, pitching for the Tankers and having a fabulous season. He completed his military obligation in two and a half years.

In 1962, Pedro was on his way to Erie, Pennsylvania to catch up with the Minnesota Twins (formally the Senators) farm system. He played with the Twins organization from 1962 through 1966. It was in 1966 that Pedro was set to make his move to the Twins Major League Club when some disagreements surfaced within the team's management. Pedro was subsequently released.

For the next three years Pedro took his pitching talent north to the Provincial Leagues of Canada. While there, he enjoyed great success with the team from Coaticook, and wrapped up his Canadian baseball career as the Sherbrooke Allouettes Most Valuable Player.

At the conclusion of his 1969 season, Pedro received a personal invite from Ted Williams to pitch a batting practice for the Washington Senators. He performed well was signed by the organization the very next day. At the start of the 1970 season, Pedro was pitching for Washington Senators (Double AA) Pittsfield team. Through 1971, Pedro was sent up and down the organizations farm club ladder, spending time with the Burlington (Class A) Team and the Denver (Class AAA) Team.

By the conclusion of the 1971 season, Pedro had become quite dissatisfied with how things were progressing within the organization. In his frustration, he traveled south of the border to Mexico where he continued to play baseball through 1975 season for a variety of teams including Puebla, Tampico Diablos, Chiuaua, Veracruz, Aquascalientes, San Fran Macrois and Puerto Plata.

By 1976, Pedro had a family of his own realized that a career change was necessary. He attended Boriqua, College in Washington DC and later pursued a career in community service with the county's department of recreation. He would be an instrumental part of the county's outreach program for children for over 19 years. He satisfied his desire for the game of baseball by participating in baseball clinics and camps.
