Johnson’s return spoiled by Giants

SAN FRANCISCO -- Randy Johnson had a hard time finding the strike zone in his season debut, eight months after back surgery.

Still, the San Francisco Giants didn’t get many good swings against him.

Johnson did not give up an earned run in five innings, settling down to finish with seven strikeouts and four walks before San Francisco rallied against Arizona’s bullpen for a 5-4 victory over the Diamondbacks on Monday night.

The Giants loaded the bases in the seventh with no outs against Chad Qualls (0-1), who gave up Ray Durham’s tying RBI groundout followed by Bengie Molina’s go-ahead sacrifice fly.

Keiichi Yabu (1-1) worked two scoreless innings for his first win in nearly three years. He beat the Giants on May 20, 2005, with Oakland.

Conor Jackson drove in three runs for the Diamondbacks.

Arizona got a scare in the bottom of the eighth when third baseman Mark Reynolds fell over the railing of a photo well while trying to catch Eugenio Velez’s foul ball and banged his face on a lower rail. Reynolds was slow getting up but stayed in the game.
