The Giants acquired Don Robinson at the 1987 trade deadline to lend a hand out of the bullpen as they pushed toward a division title.
He appeared in 25 games and posted a 2.74 ERA with seven saves after the trade and the Giants went on to win the NL West crown.
The 6-foot-4 right-hander served as a swingman the following season, pitching to a 2.45 ERA and 1.14 WHIP in 19 starts and 32 relief appearances spanning 176.2 innings. That ERA was good for seventh in the National League.
In 1989, he joined the rotation full-time and went 12-11 with a 3.43 ERA, 1.12 WHIP in 197 innings for the eventual NL champs.
In total, he spent five seasons with the Giants and went 42-33 with a 3.56 ERA (98 ERA+) and 1.24 WHIP over 695.1 innings spanning 92 starts and 78 relief appearances.
Catcher Mackey Sasser was traded again during the offseason to the New York Mets and hit .267/.296/.377, while logging 0.2 WAR in nine seasons.
