Helsley allowed a hit and struck out two over a scoreless inning to earn the save in Tuesday's 3-1 win over the Pirates.
Helsley is up to 45 saves this season, though he's earned just three of them in September amid the Cardinals' struggles to find leads. He's allowed just one unearned run over his last 14 innings, posting a 19:3 K:BB in that span. The closer has enjoyed an excellent season despite pitching on a middling team, maintaining a 2.15 ERA, 1.15 WHIP and 74:23 K:BB over 62.2 innings.
