Eight Nationals were featured on the 2016 Esurance All-Star ballot, which launched Sunday. Harper was joined on the ballot by Wilson Ramos, Ryan Zimmerman, Daniel Murphy, Anthony Rendon, Danny Espinosa, Jayson Werth and Ben Revere.
Harper's scorching-hot start has made him a frontrunner for what would be his fourth All-Star Game appearance this season, but Murphy has also been very productive at the plate.
Murphy, the Nationals' biggest free-agent signing this offseason, began the day Sunday with the highest batting average in the NL (.411), and ranked third in on-base percentage (.484) and fourth in slugging percentage (.679). He has hit safely in 14 of the 16 games he has played this season, with nine multi-hit games.
Murphy has one previous All-Star game appearance in his career, in 2014 with the Mets, but with the way he is swinging the bat lately, he deserves consideration for a second.
Browsing the ballot
The other side: Royals third baseman Mike Moustakas has matured into a strong hitter over the past few seasons and is off to his best start yet. He is hitting .273/.324/.621 with six home runs, second most in the American League.
Tip of the cap: After battling injuries for much of last season, Dodgers outfielder Yasiel Puig is off to a fast start and back to being one of the most exciting players in the league. He is batting .302/.371/.444 and making highlight-reel throws from right field.
A rising star: He has been inserted as the No. 3 hitter in the Mets' lineup, and with a .920 OPS outfielder Michael Conforto has been hitting like he belongs.
