Jim Presley hits two home runs, helping the Mariners beat the Angels, 8-4, in a dramatic extra-inning comeback Opening Day victory. The Seattle third baseman’s two-run blast in the bottom of the ninth off Donnie Moore knots the game at four runs apiece, and his two-out grand slam off Ken Forsch in the following frame ends the Kingdome contest.

Will Clark homers in his first major league at-bat, facing future Hall of Fame right-hander Nolan Ryan. The 22 year-old Giants rookie first baseman’s first inning-solo round-tripper contributes to the team’s Opening Day 8-3 victory at the Astrodome.
