San Diego (25-16) at Seattle (16-24), 10:05 pm EDT

SEATTLE (Ticker) -- Jake Peavy will attempt to extend the San Diego Padres ' winning streak to eight games when they open an interleague series with the Seattle Mariners on Friday.

Fourth in the National League in strikeouts with 61 in 56 innings, Peavy is coming off a 2-1 win against Florida last Saturday. He yielded a run and five hits while striking out eight in seven innings.

The Padres lead the all-time series with Seattle, 22-16, including an 8-4 mark in the last three years.

San Diego completed its first three-game sweep of Atlanta in 14 years with an 8-4 victory on Wednesday. Khalil Greene recorded his third career multi-homer game with a pair of three-run shots.

Seattle starts Ryan Franklin (2-4, 4.20), who went 1-0 in his last two starts against Boston, allowing three runs in 11 1/3 innings.
