Washington Nationals’ lineup for tonight’s series opener with the Pittsburgh Pirates

Victor Robles went 2 for 5 with a double (his 23rd) and a solo home run (his 16th) in the 16-8 win in the series finale with Milwaukee on Sunday afternoon, leaving the Nationals’ 22-year-old center fielder 12 for 25 (.480 AVG) with five doubles and a homer over the course of the six-game homestand in Washington, D.C., in which the Nats went 5-1.

Robles also picked up his 10th and 11th outfield assists in the series with the Brewers, doing big things at the plate and out in center field.

“You’re seeing Robles being Robles,” Davey Martinez said when asked about the outfielder taking it to another level recently.

“When I first saw him last year and now this year, this is the kind of player we envisioned. Just an all-around good player, you know. The homers will come, but we’re just constantly telling him, hey swing at strikes, and just put the ball in play. He’s got tons of speed, you know, and he’s doing that, he’s hitting doubles, driving balls in, getting big hits for us and playing unbelievable defense. I’ve said this before, but you’ve got to look at him as a Gold Glover, you really do. He’s playing defense — his defense is unbelievable.”

Robles’s manager said that he’s seen the rookie outfielder’s confidence grow this season, but he’s also seen him put in the work to keep on improving.

“He’s having a lot of fun, and he works,” Martinez said. “He works hard at it every day. Today he went out there for five minutes and worked on his drop step, you know, and he goes out there every day and gets a little work done every single day.”

Robles and the Nationals are in Pittsburgh tonight, for the start of a four-game series with the Pirates.
