San Francisco (46-63) at San Diego (42-69)

Although he was subject of trade rumors earlier this week, Greg Maddux remains a San Diego Padre.

Maddux takes the mound Sunday trying to help the Padres avoid being swept in their three-game series by the San Francisco Giants, against whom the future Hall of Famer is looking to win his 30th career game.

Maddux (4-8, 4.29 ERA) is in the midst of arguably the most difficult season of his career. After winning career victory No. 350 on May 10, the right-hander went 0-5 with a 4.54 ERA over his next 14 starts before snapping the winless streak on Monday in a win over the Diamondbacks.

Despite his struggles, Padres general manager Kevin Towers told the team’s official Web site that “nothing ever got close” in talks before Thursday’s non-waiver deadline for the 42-year-old veteran.

“It wasn’t going to be a financial deal … but to do the best baseball deal,” Towers said. “We weren’t happy with the prospect we were getting back. So we chose to hold onto him.”

Maddux will look to help the Padres (42-69) snap a four-game losing streak. San Diego has lost the first two games of this series with the Giants (46-63) and was shut out 2-0 on Saturday.

Maddux is 29-14 with a 2.81 ERA in 52 starts against the Giants. He is 6-0 with a 2.33 ERA in his last 11 starts against them, including 1-0 with a 1.35 ERA in three outings this season. He has not lost to San Francisco since May 9, 2003, and the 29 wins are tied for the second most he has against any team. He has 35 victories against the New York Mets.

San Diego has lost four straight at home to the Giants, getting shut out twice and scoring only four runs in those games. But San Francisco hasn’t performed that much better at the plate, scoring nine runs. The Padres are the lowest scoring team in the majors while the Giants are the third-lowest.

On Saturday, the Padres scratched out just three hits in eight innings against Barry Zito, while Bengie Molina and Emmanuel Burriss drove in the two runs for the Giants.

“It’s as frustrating as it gets,” losing Padres pitcher Jake Peavy said. “We just have to play better. Everybody has to play better, myself included.”

San Francisco hands the ball to Kevin Correia (2-5, 5.80) to close the series.

The right-hander pitched 5 1-3 innings on Monday against the Dodgers, allowing six runs—four earned—and seven hits in the 7-6 win, his first since April 10 against the Cardinals.

“I didn’t care if I gave up 15 runs. I wanted to get a win,” Correia told the Giants’ official Web site.

Correia is 1-0 with a 4.44 ERA in three starts and 12 relief appearances against the Padres. He has not faced them this season and not started against them since 2005.
