PHILADELPHIA (Interstat) — The Chicago Cubs and Philadelphia Phillies will look to decide their three-game series Wednesday at Citizens Bank Park, with weather potentially playing a role in the finale.

The forecast calls for rain and 83-degree temperatures at first pitch. The series is tied after the Phillies’ 13-7 win Monday and the Cubs’ 7-3 victory Tuesday.

The Cubs (7-9) will send left-hander Shota Imanaga (0-1, ERA n/a) to the mound. The Phillies (8-8) counter with left-hander Jesús Luzardo (1-2, ERA n/a).

A key matchup will feature Cubs shortstop Dansby Swanson, who has homered in two of his last three games, including a two-run shot in Monday’s loss. He is 2 for 7 in the series.

Phillies designated hitter Kyle Schwarber poses a major power threat, having launched two homers and driven in three runs in Monday’s offensive outburst. He is 2 for 3 with two walks in the series.

According to Interstat’s game simulator, the Phillies are projected to win 4-3. Philadelphia is a pregame favorite of 1.5 runs, and the over/under is set at 8.

Following Wednesday’s game, the Cubs return to Wrigley Field to host the New York Mets for three games beginning Friday. The Phillies will remain home to open a three-game set with the Atlanta Braves on Friday.

These teams will meet again for a four-game series in Chicago starting Monday.
