Jonah Heim hit a game-ending RBI single with two outs in the 10th inning as the World Series champion Texas Rangers opened the season with a 4-3 win over the Chicago Cubs. Adolis García and Travis Jankowski homered for the Rangers, who unfurled the franchise’s first championship banner before the dramatic victory. Drew Smyly, the Cubs’ seventh pitcher, walked two to load the bases before Heim lined a sharp hit into right-center field. Jankowski led off the ninth with a tying pinch-hit homer after Chicago went ahead on a disputed play in the top half of the inning involving All-Star catcher Heim.
