WASHINGTON -- Nationals right-hander Chien-Ming Wang will make one more regular-season start for the Nationals before his year comes to an end, according to manager Davey Johnson. The start will most likely come against the Cardinals this weekend.

In his last outing against the Brewers, Wang lasted four innings and allowed two earned runs on eight hits. The numbers were not as bad as they appear. It didn't help that Bryce Harper had problems with the sun in center field, helping the Brewers score both runs in the fourth.

Wang is not expected to be on the playoff roster, as Johnson has said the team will likely use four starters -- Gio Gonzalez, Jordan Zimmermann, Edwin Jackson and Ross Detwiler -- in the starting rotation.

Wang had two stints on the disabled list this year because of hamstring and hip injuries. After he recovered from the hip injury, Wang spent time rehabbing in the Minor Leagues. During his Major League stint, Wang is 2-3 with a 6.60 ERA in nine games.

ASHINGTON -- On Monday afternoon, Nationals shortstop Ian Desmond stole his 20th base of the season in a 12-2 victory over the Brewers.

Desmond became the second member in Nationals history -- Alfonso Soriano is the other -- to hit 20 home runs and steal 20 bases in a season. Desmond downplayed the accomplishment, but he was happy to get the victory.

But Desmond didn't downplay that fact manager Davey Johnson played a key role in him having his best season of his career. Desmond is hitting .299 with 24 home runs and 71 RBIs. Johnson told Desmond that he was going to be the everyday shortstop no matter what happens during the season.

"Davey has been real nice to have around for me, personally. He always believed in me," Desmond said. "When we came in during Spring Training, he said 'You are going to play every single day. I don't care what you do. You are out there, you are my shortstop. No matter what.'

"To me that was like getting a multi-year contract. That's all I needed was someone's word to say, 'Hey, you are the guy.' The audition kind of went away. Now it's like go out and play your game. He believes in you, you go out and perform, and just play the game the way you know how."

Worth noting

• The Nationals are 23-12 against the four teams that are currently in playoff position in the National League. Washington is 10-8 vs. the Braves, 5-2 vs. the Reds, 5-1 vs. the Giants and 3-1 vs. the Cardinals.
