ST. LOUIS (AP) — Michael Morse homered and drove in three runs and Pablo Sandoval homered and scored twice to propel the San Francisco Giants to a 6-5 win over the St. Louis Cardinals on Thursday night in the opener of a four-game series. The Giants have won seven of eight and the Cardinals have dropped three of four to start a nine-game home stand.

Gregor Blanco scored from second on Angel Pagan’s single to center off Carlos Martinez to tie the score at 4-4 in the eighth. Pagan moved to second on Peter Bourjos’ throwing error. After Sandoval was intentionally walked, Morse doubled to deep center to drive in Pagan and Sandoval for a 6-4 lead.

Javier Lopez got two groundouts in relief of Ryan Vogelsong for his first win since Sept. 22, 2013. Sergio Romo held on for his 17th save in 19 chances.
