San Diego (38-65) at Pittsburgh (48-54), 4:05 p.m., 1090/105.7

PITTSBURGH (Ticker) -- A blistering offense has enabled the Pittsburgh Pirates to flip the switch from ice-cold to red-hot . The Pirates go for their fifth straight win on Friday when they face the San Diego Padres. After scoring 15 runs during a five-game slide earlier this month, the Pirates have rebounded by averaging 8.5 runs while posting a .355 batting average during the streak - their longest surge since winning six straight in early May. Jason Bay, Xavier Nady and Nate McLouth all homered during the series opener as the Pirates handed the Padres their ninth loss in the last 10 games, 9-1, on Thursday. Zach Duke (4-7, 4.92 ERA) looks to keep San Diego in check and keep Pittsburgh's winning streak alive. Duke has been terrible over his last three starts, allowing 20 runs - 19 earned - in 13 1/3 innings, posting an 0-2 record over that span. Cha Seung Baek (2-5, 4.94) toes the rubber for the Padres. Baek is 2-0 with a 3.41 ERA in 10 road appearances - three starts - between San Diego and the Seattle Mariners.
