DENVER (AP) — Neil Walker had a career-high six RBIs, including a three-run homer, and the Pittsburgh Pirates clinched their third straight playoff berth by beating the Colorado Rockies 13-7 on Wednesday night.

The Pirates secured at least an NL wild card as they chase first-place St. Louis in the NL Central. They trail by four games with a home series coming up against the Cardinals.

Walker provided the bulk of the offense with a bloop, two-run single in the first and a towering three-run homer in the third off fill-in starter Christian Bergman (3-1). Walker ended his night with a run-scoring single as part of a six-run ninth to break open a tight game.
