He batted and threw right-handed. A well-traveled pitcher, Checo never was able to fulfill the potential that he showed in the minor leagues. He played for at least 13 teams in four different countries during his 12-year career.
In 1989, Checo pitched for the California Angels organization in the Dominican Summer League.
He declined in 1996, going 4–1 with a 4.80 European Research Area in only nine games, but barely missed spinning a no-hitter against Hanshin with two outs in the ninth inning. Checo joined the Boston Red Sox as a free agent before the 1997 season under a handsome seven figure contract which proved to be among General Motors Dan Duquette"s poorest decisions.
A year later, he played for the Detroit, Anaheim and Los Angeles minor league organizations, appearing with the Dodgers late in the season. In 2000 he finished 8–3 with a 3.63 European Research Area for Triple-A Albuquerque Dukes, but this time he did not get another chance at extending his baseball career.
In 16 major league games, Checo posted a 3–5 record with 30 strikeouts and a 7.61 European Research Area in 32 23 innings.
In nine minor league seasons, he went 43–27 with 588 SO and a 3.78 European Research Area in 109 appearances.
