For Sunday's game, the Nats will be sending out Anibal Sanchez.
The Nationals hoped Scherzer could pitch as soon as Tuesday against the Baltimore Orioles, but the three-time Cy Young Award victor was placed on the injured list Saturday, retroactive to July 10. Over his 83.2 innings and 5-6 mark so far, Sanchez has a 3.66 ERA with 75 Ks and 33 BBs. On Saturday, Washington did it again with a 4-3 comeback victory. He has fared well against the Nationals this season, allowing only four runs (three earned) in 12 innings, and he is 1-3 with a weak 4.79 ERA in 15 career starts against the division foes. Three Philadelphia players had two hits apiece, and Rhys Hoskins had two runs. Anthony Rendon added two hits and a run for Washington in the win.
Patrick Corbin gave the Nats a solid start, striking out 10 in six innings, allowing three runs on six hits, but he left with a 3-1 deficit. Wander Suero got the win in relief while Sean Doolittle recorded his 20 save of the year. The Phillies are 47-45 on the season, 27-19 at home and 46-43 with the under.
Arrieta and the skidding Phillies - who are 14-21 since June 1 - decided they couldn't wait for him to get to 100 percent right. The Philadelphia pitching staff owns a 4.63 team ERA, positioning them 18th overall.
TOP PERFORMERS: Bruce leads the Phillies with 24 home runs and is slugging.564.
The Phillies are 2-5 in their last seven NL East games and 4-9 in their last 13 games following a loss.
The Nationals have won seven of their last eight road games and six of their last seven Sunday games.
Sanchez has been pretty consistent with his outings. Arrieta conceded six runs (five earned) in 4.1 innings against the Mets last time out before the break, leading to the defeat to bring his record to 8-7.
The hot stretch means the Nationals can proceed cautiously with Scherzer, who is 7-0 with an 0.84 ERA in his last nine starts. The veteran right-hander hasn't been sharp in three straight starts, and his ERA has plummeted to 4.67 to go with a 1.46 WHIP in 108 innings of action on the season.
