Alonso went 2-for-4 with a walk, two home runs and three RBI in Tuesday's 9-4 win over the Marlins.
He opened and closed the scoring on the night with blasts off Edward Cabrera in the first inning and Taylor Williams in the ninth. Alonso now has 101 homers for his career in only 347 MLB games, making him the second-fastest player in history to reach 100 (after Ryan Howard) and only the eighth player ever to get to 100 home runs within their first three seasons.
