The Chicago Cubs and the Seattle Mariners begin their three-game weekend series on Friday at Wrigley Field.

The Cubs, the No.1 team in the National League Central with a 45-29 record, has just split their two-game series with the Milwaukee Brewers, winning the first game 5-3 before losing the second one in a run-fest 7-8. Over the last five games, Chicago has batted .210 with 3.7 runs per game and pitched a 2.87 ERA.

The Mariners, the No.2 team in the AL West with a 37-36 slate, have lost 2 of the 3 games against the Boston Red Sox this week. Despite rock solid pitching in the series, Seattle’s offense was virtually non-existent in the two games that they lost. The Mariners averaged 4.0 runs per games in their last five games and 4.3 runs per contest in the season.
