The Nationals optioned Schultz to Triple-A Rochester on Wednesday.
The move comes after the Nationals' 5-2 loss to the Blue Jays on Wednesday, when Schultz gave up three earned runs on four hits while striking out one batter in two-thirds of an inning. The 28-year-old right-hander will return to Rochester, where he has a 2.30 ERA and 1.12 WHIP over 15.2 innings.
