Randy Johnson returned to the Arizona Diamondbacks last night and was far from perfect.

Six months after back surgery, the "Big Unit" gave up six runs in five innings against San Diego, his first start for the Diamondbacks since 2004, and the visiting Padres went on to win, 10-5.

Khalil Greene drove in four runs for the Padres.

Johnson struck out seven, but gave up six hits, including two home runs and two doubles. He walked four - two intentionally - and hit two batters. He threw 97 pitches, 53 for strikes.

The 43-year-old Johnson pitched a perfect game for Arizona 3 years ago, then spent two frustrating seasons with the New York Yankees, failing to win both of his postseason starts. Johnson, who needs 20 victories for 300, pitched in Phoenix for the first time since Oct. 2, 2004, when he defeated the Padres.

Johnson faced fellow 43-year-old David Wells. At a combined age of 87 years, 300 days, Johnson and Wells became the oldest pair of lefthanders to start a major league game. The previous mark was set April 12, when 44-year-old Jamie Moyer, of the Phillies, opposed 41-year-old Tom Glavine, of the New York Mets.
