Pedro Alvarez homered twice and scored three runs as the Pittsburgh Pirates beat the St. Louis Cardinals 12-2 on Friday night.

Travis Ishikawa added his first major league home run in nearly two years for Pittsburgh.
Gerrit Cole (1-0) gave up two runs in seven innings in his first start since losing the deciding Game 5 of the NL division series to St. Louis last October.
Miller struggled in his 2014 debut. He tied a career high by giving up five earned runs in 5 1-3 innings, including the three home runs.
Matt Carpenter hit a two-run homer for the Cardinals.
Six months removed from a taut NLDS that pushed the eventual NL champions to the brink of elimination, the Pirates sent an early message they have no plans of going away.
