Giants finish sweep of Diamondbacks

PHOENIX -- Randy Johnson fanned nine to tie Roger Clemens for second in career strikeouts Thursday night, but Arizona’s bullpen blew a lead and Randy Winn’s ninth-inning home run gave the San Francisco Giants a 4-3 victory.

Winn’s second solo home run of the game allowed the Giants to complete a three-game sweep and hand the Diamondbacks their season-worst fourth straight loss.

Tony Pena walked in the tying run in the eighth, then Chad Qualls gave up the leadoff homer to Winn. Arizona was swept for the second time in three series and has dropped eight of 10.

Johnson, who left the game with a 3-2 lead after seven innings, has struck out 19 -- in 13 innings -- in his last two starts to tie Clemens with 4,672 strikeouts.

The tying strikeout came when the 44-year-old left-hander fanned Dan Ortmeier for the third time to start the seventh inning. Johnson drew a standing ovation as he left the field. He was lifted for a pinch hitter in the bottom of the inning with Arizona leading, 3-2.

Johnson gave up two runs on six hits and walked one.
