NEW YORK -- Minutes after watching his team defeat the Mets, 6-4, on Friday night, Nationals manager Davey Johnson announced that right-hander Taylor Jordan will make his Major League debut against New York on Saturday.
To make room for Jordan, the Nationals optioned first baseman Chris Marrero to Triple-A Syracuse. Marrero appeared in eight games and was 2-for-16 (.125) with an RBI. Johnson spent about 15 minutes talking to Marrero after the game.
"It's a tough situation for a young player. He is having a heck of a year [in the Minors]. We had to take his spot," Johnson said. "I told him to keep his head up. Keep having a good year."
Ranked as the organization's No. 17 prospect by MLB.com, Jordan started the season with Class A Potomac and is now with Double-A Harrisburg, having gone a combined 9-1 with a 1.00 ERA in 14 starts between the two clubs this season. In eight Double-A starts, he has a perfect 7-0 record with 43 strikeouts, nine walks and a 0.85 WHIP.
"I think the one thing that stands out the most is his fastball command," said Harrisburg manager Matt LeCroy. "In his outings, he's pretty much commanded the baseball. He has another thing he does really well. He slows the game down and takes it one pitch at a time, and that's something that's hard to teach. It's been pretty amazing to watch. He's quick to the plate, holds runners well. So we're proud of the work he's put in and all the strides he's made since [undergoing his Tommy John surgery]."
Jordan is having the best year of his professional career, and Saturday's start would give him a jump on his Citi Field debut after having been named to represent the Nationals at the Mets' ballpark for the Sirius XM All-Star Futures Game on July 14.
While in the big leagues, Jordan is expected to make two or three starts.
Haren feels good, ready for bullpen session
NEW YORK -- Nationals right-hander Dan Haren, who is on the 15-day disabled list because of shoulder inflammation, played long toss Thursday and Friday without any problems and will have a bullpen session Saturday at Citi Field.
Haren hopes to be pitching for the Nationals when his time on the DL is up in 10 days.
"I feel good, obviously, just from rest," Haren said. "Throwing really wasn't the issue for me. When I went on the DL, it was more precautionary, lack of execution on my part. I'm just getting back to being 100 percent. Obviously, pitching wasn't working for me where I was. I took some time off, I took some medicine. I feel really good now. I'm excited, obviously, to throw a bullpen [session] and stuff."
Before going on the disabled list, Haren was having his worst season in the big leagues, going 4-9 with a 6.15 ERA in 15 starts.
Harper likely to return to Nats on Monday
WASHINGTON -- Bryce Harper did not play a Minor League game for Double-A Harrisburg on Friday. It was just a day off. Harper, who is on a rehab assignment, will play against Bowie on Saturday. Harper is expected to rejoin the Nationals on Monday against the Brewers.
So far, Harper hasn't had any problems with his left knee, which he injured when he collided with the right-field wall at Dodger Stadium last month. Harper didn't go on the 15-day disabled list until June 1.
"He has five at-bats and he has been all over the place. He is 20 years old," manager Davey Johnson said. "The punishment he has been giving is diving back into the bag. He has had to hustle -- first to third, triple. He has done just about everything and he has gone full speed. There hasn't been any noticeable swelling in the area."
• Nationals catcher Wilson Ramos has started a rehab assignment with the Gulf Coast Nationals. He caught three innings and went 0-for 1 on Friday. Ramos is going to catch five innings on Saturday and have the day off Sunday. Johnson is hoping that Ramos moves up and plays for the team's other Minor League affiliates next week. Ramos has been on the disabled list because of a hamstring injury.
