A soft-throwing righthander with excellent control, Laskey made the Topps and Baseball Digest All-Rookie teams as a starting pitcher in 1983, going 13-12, 3.14 for the Giants. His ERA rose and his strikeout total fell each year until 1986, when he was sent to the bullpen, and he spent all of 1987 working in relief for the Tigers AAA Toledo club. In 1988, Laskey posted a 5.18 ERA in 17 relief appearances with the Indians and was released August 21.
