Lake, Rizzo HR, Lead Arrieta, Cubs over Cardinals
A day after the Cubs tagged St. Louis ace Adam Wainwright, they came back to beat Michael Wacha (2-3).

Chicago's bullpen combined to pitch 3 2-3 scoreless innings. Brian Schlitter (1-0) got two outs for the win and Hector Rondon worked around a pair of leadoff singles in the ninth for his third save.
