• VOTE: Esurance MLB All-Star Game Ballot
Harper is bidding for this third consecutive All-Star Game start, and he is once again performing well through April. He is batting .391/.509/.772 with nine homers, and he scored 32 runs, a Major League record for the season's first month.
Harper's resurgence through the first month has been huge for the Nats after his disappointing season in 2016. But Zimmerman batted .420/.458/.886 in April, with 11 home runs and a Major League-leading 29 RBIs and 1.345 OPS. Zimmerman is traditionally not a fast starter, so he has only made one All-Star Game appearance in his career (2009).
If the Nationals' offense keeps going at close to its current pace, the club should be represented by quite a few players in Miami at the Midsummer Classic.
