MLB: San Francisco 5, Arizona 3

Randy Winn hit a two-run homer Saturday to lead the San Francisco Giants to a 5-3 victory over the Arizona Diamondbacks.

Randy Johnson returned to Arizona in his first start as a visitor and walked seven batters before leaving in the fourth inning. Still, the Giants got their fifth win in a row, with Edgar Renteria driving in two runs with a double, and Emmanuel Burriss also contributing an RBI.

Johnson made his second start this season against Arizona — his former team — but lasted only 3 1/3 innings, allowing two runs on three hits.

Justin Miller (1-0) got the win after allowing one run in 1 2/3 innings.

Eric Byrnes and Justin Upton each homered for the Diamondbacks, who have lost three of four.

Max Scherzer (0-2) took the loss after allowing four runs on five hits.
