Unit watches Sanchez's no-no with pride

Future Hall of Famer relishes teaching up-and-coming lefty

SAN FRANCISCO -- Randy Johnson has tossed two no-hitters (one a perfect game), so he knows the feeling. Sitting in the dugout on Friday night at AT&T Park, he watched his pupil secure one, too, vs. the Padres.

In a Giants rotation that includes two other former Cy Young Award winners (Tim Lincecum and Barry Zito) and a 10-game winner this season (Matt Cain), it's obvious Johnson would spend his time mentoring Jonathan Sanchez, a young lefty who has struggled to be his best. Since Johnson signed a free-agent contract to join San Francisco, he's been a willing adviser, Sanchez a willing listener.

"I've told him that his stuff is as good as anybody's in the rotation," Johnson told reporters after the Giants' 8-0 win against the Padres. "He needs to be consistent with it from pitch to pitch, from inning to inning, from game to game.

"Timmy, Matt and Barry, they're established," Johnson said. "I've had a lot of the same kind of problems [Sanchez] has had, as far as mechanics and stuff like that."

The 45-year-old has said he relishes the role of working with players a decade more his junior. They seem to enjoy it, too.

In June, Sanchez told MLB.com, "When I pitch, [Johnson] tells me what I do right, what I do wrong."

Sanchez left the Big Unit with little to critique following his 51st career Major League start.

"He was locked in today," Johnson said. "It was a lot of fun to watch. I feel pretty fortunate."
