Game 4 of this NLDS was supposed to take place last night but got rained out, and the weather was one of the reasons I did not release a pick yesterday. We'll see the same scheduled pitching matchup on Wednesday instead, and I think the day off will benefit the home team here at Wrigley the most.

Jake Arrieta (14-10, 3.53 ERA) will take the ball for the Cubs. He'll make his first start since Sept. 26 as he's been bothered by a minor right hamstring injury, and the extra day off should do him good. Arrieta has been terrific at Wrigley all season going 5-2 with a 2.90 ERA in 10 starts.

The Nats turn to Tanner Roark (13-11, 4.67 ERA) despite having the option to trot out Stephen Strasburg on regular rest. Strasburg might not even be available out of the bullpen. Asked about Strasburg's availability Nationals manager Dusty Baker said Strasburg was "under the weather" and cited a change in weather, air conditioning in the team hotel and mold in Chicago. Moldy hotel room? Well played Cubs, well played.

Roark was torched four six runs on seven hits and five walks in 4 2/3 innings at Philadelphia his last time out on the road, and I just don't see him beating the Cubs here.

Nationals are 1-4 in their last 5 Divisional Playoff games. Cubs are 8-2 in their last 10 Divisional Playoff games. Cubs are 6-2 in the last eight meetings at Wrigley. Let's go with the Cubs to close out the series and advance to the NLCS.

My selection is an 8* play on Cubs.
