Harrison Bader and Dylan Carlson homered during a seven-run burst in the fourth inning and the St. Louis Cardinals beat the Cincinnati Reds 10-6 on Sunday.

Nolan Arenado hit his 20th home run and tripled, and Tyler O'Neill also connected for the Cardinals.

Cincinnati starter Sonny Gray (2-6) was tagged for a career-high eight runs, allowing eight hits and a walk in 3 1/3 innings.

The Cardinals trailed 3-2 in the fourth before the first five batters reached base, including Bader's three-run shot halfway up the lower deck in left-center field. Bader raised his right fist in triumph as he rounded second base.

Andrew Knizner followed with a double and Carlson hit a drive deep into the visitors' bullpen.

Adam Wainwright (7-6) on Tuesday will make his first career appearance at Progressive Field in Cleveland, boosting to 33 the number of ballparks in which he's pitched regular-season games. Houston's Joe Smith leads active players with 37 ballparks.
