Practically from their birth, the Toronto Blue Jays invested in scouts that scoured Latin America for talent. Luis Leal was one of their finds: the Jays signed him in 1979 when they spied the 22-year old righthander throwing in the Venezuela leagues. The following season they inserted Leal into their rotation and he stayed there for nearly six seasons, helping chew up innings despite a reputation as a streaky pitcher.
Leal, who struggled with his weight at times in his career, slotted in behind Dave Stieb and Jim Clancy in the Toronto rotation in the early 1980s. He won 12 games in 1982 and 13 in each of the next two seasons. In 1985 when Toronto won their first division title, Leal pitched poorly in the first half and lost his spot, earning a demotion. He suffered an arm injury the following year and never returned to the big leagues.
