Tommy Edman's long drive to left field nicked off the glove of outfielder Alex Call for a two-run, two-out double to cap St. Louis' five-run ninth inning in a 6-5 victory over the Washington Nationals on Wednesday night.

St. Louis moved 9 1/2 games ahead of Milwaukee for the NL Central lead, winning for the 20th time in its last 23 home games. The Cardinals are a season-high 25 games over .500 at 81-56.

Edman doubled to left off reliever Kyle Finnegan (5-3) to cap the rally.

Paul Goldschmidt hit his 35th homer, a solo homer off Cory Abbott leading off the fourth. Goldschmidt leads the NL with 108 RBIs. He's one homer shy of tying his career best.

Jordan Montgomery turned in another strong outing with his new team. Montgomery allowed one run on three hits over 6 2/3 innings and did not get a decision. He struck out six, walked two and left with it tied 1-1.

Jake Woodford (4-0) pitched the ninth for the victory.

Cardinals OF Dylan Carlson was placed on the 10-day disabled list with a left thumb strain. He is not expected to swing a bat for at least the next four days.

Adam Wainwright (10-9, 3.21) will face Washington RHP Josiah Gray (7-9, 4.91) in the finale of the four-game series on Thursday afternoon. Wainwright and batterymate Yadier Molina will likely tie the career record for most games together at 324, which is currently held by the Detroit Tigers duo of Mickey Lolich and Bill Freehan (1963-1975).
