PITTSBURGH — The collapsing Chicago Cubs were eliminated from playoff contention shortly before losing their eighth straight game, falling 4-2 to the Pittsburgh Pirates on Wednesday night.

Back-to-back wild pitches by David Phelps in the eighth inning enabled Pittsburgh to score the winning run. Just before Phelps’ bout with wildness, Milwaukee clinched the second NL wild card with a 9-2 victory at Cincinnati. The Cubs will miss the playoffs for the first time since 2014.

Phelps entered in relief with the score tied 2-2 and walked Pablo Reyes to put runners on first and second with one out. Jose Osuna drew a walk before scoring on the wild pitches.
