In
1983, Hammaker's best season, he led the
National League with an
ERA of 2.25, a
WHIP of 1.039,
BB/9IP of 1.67, and
strikeout to
walk ratio of 3.97. That year Hammaker won 10, lost 9, and made the
National League All-Star team. (Through June, his record was 9–3 with an ERA of 1.52.)
1983 All-Star Game Hammaker made the
National League All-Star team in 1983, but did not fare well, surrendering seven earned runs in 0.2 inning pitched; and he gave up the only
grand slam in All-Star Game history, to
Fred Lynn. The American League prevailed 13–3 for their first win in
twelve years.
1987 NLCS In Game 7 of the
1987 NLCS, Hammaker, pitching for
San Francisco, gave up a three-run
homer in the second inning to
José Oquendo, a utility infielder who had hit only one home run that season. The
Cardinals won 6–0 to advance to the
World Series.
Religion While with the Giants, Hammaker and teammates
Scott Garrelts,
Dave Dravecky and
Jeff Brantley became known as the "God Squad" because of their strong Christian faith. Forgoing the hard-partying lifestyle of many of their teammates, they preferred to hold Bible studies in their hotel rooms while on the road. ==Personal life==
