Schmidt, who went 18-7 with a 3.20 ERA last year, is 0-1 with a 4.62 ERA in four starts since beating Colorado on April 10. More alarming is the fact that he has issued a total of nine walks over his last two outings.
The hard-throwing right-hander surrendered six runs—four earned—and eight hits in 6 2-3 innings of San Francisco’s 9-8, 10-inning win at Arizona on Monday.
Schmidt is 4-4 with a 4.50 ERA against the Nationals’ franchise in 12 career appearances, including 11 starts. He is 1-0 with a 1.80 ERA in two career starts at SBC Park against the former Montreal Expos.
Nationals outfielder Jose Guillen sustained a bruised left triceps and left the game after being hit in the left elbow by a pitch from Tyler Walker in the seventh. Guillen went 0-for-3 to snap a six-game hitting streak.
San Francisco has lost three straight after a six-game winning streak. Giants second baseman Ray Durham missed Friday’s game due to a strained left groin and remains listed as day-to-day.
Washington is seeking another consistent effort from starter John Patterson, who is 2-0 with a 1.35 ERA over his last four starts.
Patterson did not receive a decision Sunday against the New York Mets after allowing a season-high three runs and six hits while walking three in six innings of a 6-3 Washington loss.
“I didn’t have my best command,” Patterson said. “I gave my team a chance to win.”
The 27-year-old right-hander is 0-1 with a 6.32 ERA against San Francisco in five career appearances, including a pair of starts. Patterson faced the Giants once last season and lasted just 3 2-3 innings, allowing four runs and four hits. He did not receive a decision in an 8-5 loss on Aug. 16.
