The St. Louis Cardinals have plenty of postseason pedigree, but what happened on Friday in their Wild Card Series opener was downright shocking. The Philadelphia Phillies have shown time and again this season that they are a resilient unit. Bouncing back from a horrendous 22-29 start, the Phillies managed to turn their season around under Rob Thomson following the dismissal of Joe Girardi.Making their first postseason appearance in more than a decade, the Phillies’ resilience turned out to be a bit too much for the playoff-tested Cardinals to handle.St. Louis Cardinals@CardinalsFinal3426262Final https://t.co/LSRDuwgP3p"Final" - St. Louis Cardinals Jacob Fisher@_jacobmfisher@Cardinals56241@Cardinals https://t.co/rQsfi5KkjjRocky@rmchandlerjr@Cardinals This is all on Marmol... leaving Helsley in after he couldn't find the plate and loaded the bases was bad.. not having someone up and getting ready after the 1st batter reached was worse, and finally pushing your closer to get 5 outs when he's dealing with a jammed finger...

In doing so, they silenced the sellout crowd at Busch Stadium. Several Cardinals fans could be seen heading for an early exit owing to the stunning collapse.Talkin’ Baseball@TalkinBaseball_they're leaving 2163106they're leaving 😬 https://t.co/I9i7GhskXe"They're leaving" - Talkin' BaseballGarrett Hall@Gart42@Cardinals Cardinals fans are so spoiled it’s unreal, cannot believe some of them started leaving like that in a POSTSEASON game.

Went from great call to spectator. Watched Helsley lose all control and did nothing. Brings in Pallante and let’s the bus run him over again and again. Best of three and he gave up on game 1.1@Cardinals Marmol blew that one. Went from great call to spectator. Watched Helsley lose all control and did nothing. Brings in Pallante and let’s the bus run him over again and again. Best of three and he gave up on game 1.The Cardinals, who were 74-3 heading into Friday in terms of leading after eight innings, looked set for another win after Juan Yepez hit the first go-ahead pinch-hit homer in franchise history during the seventh.From then on, the tables turned quickly as Cardinals fans watched on in disbelief. Alec Bohm was credited with an RBI after he was hit by a pitch with bases loaded in the top of the ninth. Jean Segura scored a go-ahead single to put the Phillies 3-2 up.RED OCTOBER IS UPON US@Derek9306@Cardinals81@Cardinals https://t.co/umXGHNOiksEdmundo Sosa added another run when he scored on Bryson Stott's grounder to first base. Brandon Marsh drove in another run before Kyle Scwarber’s sacrifice fly gave the Phillies enough breathing room.Cardinals Talk@theredbird_way@Cardinals Favorite this tweet for the 9th inning to be wiped from your mind35712@Cardinals Favorite this tweet for the 9th inning to be wiped from your mind https://t.co/b6NZWakj4yScott Glenn@ScottGl70942526@Cardinals Really bad job today of bullpen management.

Could have shortened bullpen if they let him go longer.9@Cardinals Really bad job today of bullpen management. Cardinals managers really seem to struggle with this in playoffs.

It was the first time in 94 postseason games that the 11-time World Series champions blew a lead of at least two runs going into the ninth.The St. Louis Cardinals have enough postseason experience, but will that be enough? The Phillies last made the playoffs in 2011, where they fell short against the Cardinals in a dramatic pitchers' duel between Chris Carpenter and Roy Halladay in Game 5 of the NL divisional series. Molina and Albert Pujols played for the St. Louis Cardinals that night while erstwhile ace Adam Wainwright, pitching out of the bullpen this series, was also there to celebrate.The two sides meet again tonight for Game 2 of the NL Wild Card Series, and the Phillies are well-positioned to earn payback. However, the Cards have plenty of postseason experience and despite their incredible collapse last night, it’s far from over.For more news and updates, go to the Sportskeeda Baseball page.
