Tyler Moore has become the Nationals’ regular left fielder against left-handed starting pitchers, and Davey Johnson does not feel the need to declare as much. “Have I gone any other way?” Johnson said. “Yeah, I mean, pretty much.”

Since Moore returned from the minors, he has been one of the Nationals’ most effective hitters. In his second stint in the majors, Moore is 9 for 20 with five walks, two doubles and two homers. He has forced his way into the lineup, and may be pushing for more playing time.

“There’s been some discussion on Tyler of, ‘not just lefties,’ ” Johnson said. “And if you’ve been paying attention here lately when they change to a right-hander, I’ve been leaving the at-bat with him. So his performance has not gone unnoticed by the manager or the staff, or all of baseball.”
