TUCSON, Ariz. -- The D-backs will get a look at a familiar face on Tuesday.

The only thing is, Randy Johnson will be wearing a different uniform.

Johnson, who his just five wins away from 300, is scheduled to start for the Giants when the D-backs visit Scottsdale Stadium.

"Everybody is going to enjoy it, but we see it as another day of work," D-backs right fielder Justin Upton said of the matchup.

Will it be strange to see him in a Giants uniform?

"No, we've seen pictures," he said. "It's OK."

Johnson pitched for the D-backs from 1999-2004 and then again from 2007-08. He signed a one-year, $8 million contract with the Giants after rejecting an offer believed to be around $2.5 million from the D-backs.

The Big Unit tossed two innings on Friday in his first start of the spring and has said that his back feels better early in camp than it did the past two years when he was coming off surgeries.

"It will be strange," left fielder Conor Jackson said. "He was with us the last couple of years, he's a shoo-in for the Hall of Fame, so I think he's a guy this whole team has a lot of respect for. I've yet to face him, so it will be an interesting first for me. I can't imagine he's too comfortable an at-bat."
