Happy birthday, Kenley Jansen! Ever since you stepped onto the mound for the Dodgers in 2010—and especially after becoming their closer in 2013—seeing batters desperately flail has been as delightful a tradition as peanuts and Cracker Jack. From clutch saves to milestone strikeouts, your electric cutter deserves its own fan club.Here's hoping this year is filled with more ninth-inning magic (and fewer stressful extra innings)! Keep making hitters shake their heads all the way back to their dugouts, because watching opposing players question life choices never gets old. Have a fantastic day—you bring joy faster than your fastball!
