WASHINGTON -- As Jayson Werth settles back into his everyday role in the Nationals' outfield, Tyler Moore will struggle to find his way onto the field.
After playing in 45 games in left field, right field and at first base, the 25-year-old rookie now finds himself pushed farther down manager Davey Johnson's bench. Werth will be brought along on a day-by-day basis as he nears full strength in his recovery from a broken left wrist, but his return occupies one spot in the Nats' already crowded outfield.
Michael Morse and Bryce Harper will continue to see the majority of starts alongside Werth, who will play a lot of center field and occasionally alternate with Harper in right. Roger Bernadina will also continue to factor into the outfield mix thanks to his hot hitting in July.
It all leads to a diminished role for Moore, who has become the latest young Nats prospect to find early success in the big leagues. Moore will primarily play in left field when he gets spot starts, and he will also be used as a pinch-hitter. In 100 at-bats entering Friday's action, Moore was batting .290 with an .869 OPS, six home runs and 16 RBIs.
"I'm just glad we're winning, having the season we're having," Moore said. "I just want to continue to do that, and any way I can get on the field to help this team out is what I want to do."
After Werth was activated from his rehab assignment at Class A Potomac on Thursday, Johnson said he initially preferred to send Moore down, so that he could continue to get at-bats. Instead, Henry Rodriguez was placed on the 15-day disabled list with a lower back strain, forcing Johnson to "get creative" to give Moore some at-bats.
Winter league action will be a possibility after the season for Moore to stay in a rhythm at the plate.
"That'd be a great thing for me, I've heard a lot of good things about it -- the Dominican or Venezuela -- something like that," Moore said. "I'm excited, I just want to kind of stay focused on this right now, though."
Jordan Zimmermann had his throw day on Thursday, and manager Davey Johnson said the right-hander "felt great." Zimmermann was initially slated to pitch in Friday's doubleheader with the Marlins, but was pushed back a day due to lingering soreness while getting ready and some minor inflammation in his right shoulder. Zimmermann will start Saturday against the Marlins
Chein-Ming Wang pitched 6 2/3 innings in a rehab start with Double-A Harrisburg on Thursday night, allowing three runs on seven hits while striking out two and walking one. Wang threw 99 pitches, 65 for strikes, and allowed a solo home run in the third inning.
Michael Morse dealt with a stomach virus on Thursday, preventing him from eating adequately into Friday. As a result, he was held out of the first game of Friday's doubleheader with the Marlins. Bryce Harper also sat out the opener, but both will play in the second game.
