SAN DIEGO -- The San Diego Padres will once again take the field looking to alleviate themselves of a six-game losing streak that is gaining momentum in the wrong direction.

In losing their sixth straight game, this time at the hands of the Seattle Mariners, the Padres dropped to 32-49 on the season and into sole possession of last place in the National League West. The Padres are 8 1/2 games back of the division-leading Arizona Diamondbacks.

The Mariners, who have struggled this season as well, won for only the fifth time in their past 13 games. Both teams sit in last place in their respective divisions with the Mariners 18 1/2 games back of the American League West-leading Los Angeles Angels.

The Padres will turn to Cha Seung Baek for Saturday's game. Baek is 1-2 on the season with a 5.11 ERA. He allowed six runs on eight hits in 6 1/3 innings in his last outing on June 21 against the Detroit Tigers.

The Mariners will counter with Carlos Silva who sits at 3-9 this year with a 5.92 ERA.

Pitching matchup
SD: RHP Cha Seung Baek (1-3, 5.27 ERA)
Baek will face his former team for the first time when Seattle makes its annual visit to San Diego. Baek has been a part of the Padres rotation with injuries to Chris Young and Shawn Estes. In his last start, Baek allowed six runs on eight hits with seven strikeouts for the loss against the Tigers. Baek came to the Padres on May 28 in exchange for right-hander Jared Wells.

SEA: RHP Carlos Silva (3-9, 5.92 ERA)
Silva is in the throes of a career-worst nine-game losing streak. In his last start in Atlanta, he lasted only four innings, allowing four runs and nine hits, including a season-high three home runs. The veteran right-hander finished Sunday tied for the Major League lead for most earned runs allowed with 61. He is 1-0 with a 3.44 ERA in his career against San Diego and is making his first career appearance at PETCO Park.
