Happy Birthday, Jason Isringhausen! May your celebration have as much zip as your legendary fastball and be as unpredictable (yet delightful) as that devastating knuckle-curve. Just like in 2006, when you helped pitch the Cardinals to World Series glory, we hope today brings you plenty of cheers and fewer curveballs.From All-Star appearances to championship rings, you've always known how to close out a great performance. Here's hoping this birthday is another perfect save—filled with laughter, joy, and perhaps fewer stressful innings than you're used to. Enjoy your special day; you've certainly earned it with every strikeout thrown!
