Nationals' Wednesday afternoon lineup: Tyler Moore starts at first in series finale in L.A.

With veteran first baseman Adam LaRoche out of the lineup once again as he rests a tight back, Washington Nationals' manager Matt Williams is turning to recent call-up Tyler Moore at first base this afternoon in the series finale with the Los Angeles Dodgers.

Moore, 27, spent the majority of the 2014 campaign at Triple-A Syracuse, but he has started 13 games and made 18 appearances at first base with the Nationals this season with 31 starts and 46 appearances at first over the last three years since he made his MLB debut in 2012.

In 35 games and 79 plate appearances with the Nats this season, the '08 16th Round pick out of Mississippi State University is 15 for 71 (.211/.291/.366) with two doubles and three home runs.

MW says LaRoche (back) is doing better today. Could be available off the bench this afternoon and should be fine to return to lineup Friday

With the Nats' top affiliate at Triple-A Syracuse, the right-handed hitting and throwing infielder and outfielder put up a .265/.367/.434 line with 84 games and 354 plate appearances over which he hit 21 doubles and 10 HRs before he was recalled when rosters expanded this week. Moore's last start at first base was back on May 25th in Pittsburgh's PNC Park.
