Washington Nationals catcher Matt Wieters "is a little sick" on Tuesday and considered day-to-day.
This explains why Wieters is being replaced by Jose Lobaton in the starting lineup following a day off. Lobaton will bat eighth against right-hander Taijuan Walker and the Arizona Diamondbacks.
Wieters owns a .301/.400/.534 slash with 4 home runs, 12 RBI's and 10 runs scored in 85 plate appearances so far this season.
