Freese struggled this season to overcome a back injury in spring training and had nine homers and 60 RBIs. But just like teammate Carlos Beltran, he's an October star with seven homers, 29 RBIs and a .325 average in 36 career postseason games.
Adams' power hitting helped the Cardinals overcame a mid-foot sprain to cleanup man Allen Craig in early September and he hammered a first-pitch fastball from Melancon well over the right-field wall for his first RBIs of the series.
The Pirates scratched out their lone run on two infield hits and the single by Alvarez that looked to be a harmless inning-ending groundout before it hit the bag.
Freese was a hometown hero in 2011, both the NLCS and World Series MVP. He singlehandedly got the Cardinals to Game 7 of that World Series against Texas with a two-run triple with two outs and two strikes in the ninth and then ended Game 6 with a leadoff homer in the 11th.
"He's a stud. He's a big-time player at big-time moments," Wainwright said. "And that's what we expect of him and that's what he continues to deliver."
The snapshot moment from the title run came when Freese joyously flung his helmet between the legs a few steps from the celebration waiting at the plate.
At 23 years, 31 days, Cole was the youngest NL pitcher to start Game 5 of a division series and the fifth-youngest NL pitcher to start a winner-take-all postseason game, according to STATS.
Counting the postseason, Cole didn't allow a homer in six straight starts. That ended when Freese connected for a 2-0 lead in the second.
Starling Marte robbed Matt Carpenter of a hit with a diving catch near the left-field line in the third.
Neil Walker drew a one-out walk in the first off Wainwright, who issued just 35 walks in the regular season for third-best in the majors and none in Game 1, but went no farther. Carpenter was perfectly positioned at second base to snare a soft liner by Alvarez, flipping to first for an easy double play.
NOTES: Lou Brock, clad in a red sport coat worn by all the Cardinals' Hall of Famers, bounced the ceremonial first pitch, with pitcher Joe Kelly making a nice scoop. ... Josh Young, in town for the musical Evita, sang the national anthem. ... This was the 24th meeting between the teams this season, with each team winning 12 times.
