Two-time Cy Young winner Tim Lincecum pitched so poorly — 15 losses — that he got relegated to the bullpen for the division series.
And don't forget that Posey was coming off a broken leg that wiped out most of his 2011 season, making a great comeback of his own.
"Unreal," Romo said, with champagne dripping off his scraggly beard. "That guy's definitely the MVP of our team. We believe he's the MVP of the league. We wouldn't be here without him, that's for dang sure. He's the one that's been the face of the team all season long. What a great story with all he's been through last year."
They pulled it all together during the streak of three improbable wins in Cincinnati.
The Reds will remember the first inning of the series, where everything changed. Ace Johnny Cueto pulled muscles in his right side and had to leave the game. He wound up getting dropped from the playoff roster because of the injury.
Latos pulled them through that opening game, pitching in relief on short rest for a 5-2 win. Latos came to Cincinnati from the Padres at a high price — two first-round draft picks — and with a clear purpose in the offseason. He was expected to take them to the next level.
The right-hander allowed three hits through the first four innings, then fell apart in the fifth. Brandon Crawford had an RBI triple and scored on shortstop Zack Cozart's error. A four-pitch walk and a single loaded the bases for Posey.
As soon as he connected, Reds catcher Ryan Hanigan stood and turned away, unable to watch the ball head for the seats.
Cincinnati's 17-year history of playoff futility was about to go on.
NOTES: Posey's other career grand slam came on July 7, 2010 at Milwaukee. ... The Reds are 3-3 in winner-take-all playoff games, including 1-2 in best-of-five series and 2-1 in best-of-seven series. .. Teams that lose the first two games in a best-of-five series are 7-59 all-time. ... Cain gave up six hits and three runs in 6 2-3 innings, the longest appearance by a Giants starter during the series.
