MILWAUKEE (AP) — Nolan Arenado homered twice in the first three innings to help the St. Louis Cardinals trounce the Milwaukee Brewers 15-4 in a milestone performance for Adam Wainwright and Yadier Molina. St. Louis hit a season-high six homers. Arenado drove a two-run shot in the first inning and went deep again in the third for his 28th and 29th of the season. Molina hit a grand slam, Harrison Bader had a three-run shot, Tyler O’Neill provided a two-run blast and Edmundo Sosa added a solo shot. It marked the 300th game to feature Wainwright and Molina as the Cardinals’ starting pitcher-catcher combination. That total makes them the fourth-most prolific battery of all time.
