Chicago Cubs fall below .500 for the first time since April 17 after a 5-0 loss to the Cardinals. Jake Arrieta allowed a pair of two-run home runs to Yadier Molina in the second and Matt Carpenter in the third. Cubs were held to four hits against Adam Wainwright and two relievers. Cubs pitcher Brian Duensing’s scoreless streak ended at seven games after Molina hit his second homer in the seventh. Roughly about 25 percent into his contract year, Jake Arrieta now has a 5.44 ERA and one quality start since the first weekend of the season. The Chicago Cubs, who fell below .500 with their seventh loss in nine games, sit 3 1/2 games back.
