MIAMI -- Nationals manager Davey Johnson announced his rotation after his team returns from the All-Star break on Friday at Nationals Park.
Right-hander Stephen Strasburg will start Friday's series opener against the Dodgers, while left-hander Gio Gonzalez and right-hander Jordan Zimmermann will start Saturday and Sunday, respectively.
Right-hander Dan Haren will open the series against the Pirates on Monday, while the Nationals are hoping that left-hander Ross Detwiler will start the second game of the set on Tuesday. Detwiler is on the disabled list because of back issues. He may have to do a rehab assignment before he returns to the Major League staff. If Detwiler is not ready, right-hander Taylor Jordan will make the start.
Detwiler had a cortisone shot recently to get rid of the pain in his back, according to Johnson.
Harper ejected after arguing called third strike
MIAMI -- Nationals outfielder Bryce Harper was ejected for the second time this season for arguing balls and strikes, being thrown out in the eighth inning of Saturday's 2-1 loss to the Marlins.
With the Nats leading, 1-0, Harper was called out on strikes by home-plate umpire Hunter Wendelstedt. Harper was clearly upset, thinking the ball was out of the strike zone.
Wendelstedt immediately ejected Harper. Manager Davey Johnson tried his best to intervene, but the damage had already been done. It didn't help that Harper was called out on strikes two innings earlier.
"I gave [Wendelstedt] my peace of mind," Harper said. "I got out what I wanted to get out. … I got tossed."
The Nationals had a chance to score in the 10th inning against Marlins closer Steve Cishek. They had runners on second and third with one out, but both Scott Hairston and Ryan Zimmerman struck out to end the threat.
Teammate Ian Desmond didn't mince words ,saying that Harper should have bit his tongue and remained in the game. It was Hairston who entered as Harper's replacement.
"I usually try to say the right thing, I guess, but we have to have our three-hole hitter in the game right there. It's as simple as that," Desmond said. "The person that hits in the three-hole is usually your best hitter, one of your better players, usually the best. There is no doubt that his skill set is there, but … in a one-run ballgame ... we need that game.
"That's the game you have to stay in, no matter what. Sometimes you have to bite your tongue. You get bad calls against us. The umpires didn't look at the replays or anything like that. But you have to stay in the game -- you have to for your team."
Even Johnson thought Harper was wrong.
"He can't do that," the manager said. "Take it out on the pitcher. You can't take your frustration out on the umpire."
• Johnson doesn't know who will replace Zimmermann on the National League roster in Tuesday's All-Star Game. Zimmermann will not pitch because of neck issues. Johnson believes a decision would have to be made sometime on Saturday. Johnson already recommended three of his pitchers -- Strasburg, Gonzalez or Rafael Soriano -- to replace Zimmermann in the Midsummer Classic.
"It would be fine with me if no one is taken," Johnson said.
Johnson will be one of NL manager Bruce Bochy's coaches during the All-Star Game.
