With scouts from about a dozen teams watching, Josh Johnson tied a career high with six walks as the Miami Marlins rallied from a two-run deficit and beat the San Diego Padres 5-4 in 10 innings Sunday.

Johnson, the 2010 NL ERA champion, allowed two runs - one earned - and two hits in five innings with four strikeouts. Miami, a disappointing 47-54 following a $191 million free-agent spending spree, already has dealt Hanley Ramirez, Omar Infante, and Anibal Sanchez in recent weeks and has discussed possible trades involving Johnson.

He is 54-30 with a 3.13 ERA for Marlins over the past eight years and is signed through next season at $13.75 annually. He also walked six against Toronto on June 18, 2006.

Justin Ruggiano hit a game-ending single off Brad Brach (0-2) after Jose Reyes doubled leading off and Carlos Lee was intentionally walked.

San Diego loaded the bases with two outs in the 10th against Ryan Webb (4-2), but Chase Headley flied out. The Padres stranded 14 runners.

San Diego starter Clayton Richard gave up two runs and five hits in 5 1-3 innings.

Mark Kotsay's RBI double in the third and Richard's sacrifice fly in the fourth built a 2-0 lead for the Padres, but the Marlins went ahead 4-2 in the sixth on Lee's sacrifice fly off Dale Thayer, Ruggiano's RBI single and Donnie Murphy's two-run triple over Kotsay' in right.

Yonder Alonso's two-run homer against Edward Mujica tied the score in the eighth, a 410-foot drive to right. Alonso went 5 for 13 with a home run and five RBIs in the series.
