Sal Stewart slugged a pair of three-run homers, Eugenio Suarez and Elly De La Cruz each hit solo shots, and the Cincinnati Reds beat the visiting San Francisco Giants 8-3 on Wednesday.

Stewart went deep for the second straight night and has seven homers to lead all rookies. Suarez went 3-for-4 and Spencer Steer had a pair of singles for Cincinnati, which has won three of its last four games.

Reds starter Rhett Lowder (2-1) allowed three runs on five hits with one walk and four strikeouts over a career-high 6 2/3 innings.

Daniel Susac doubled in two runs and had two hits for San Francisco, which lost its fourth straight.

Cincinnati claimed a 4-0 lead in the first inning against Tyler Mahle (0-3). With two on and one out, Stewart hit a three-run blast on a liner to right-center field. Suarez followed with his third homer, a 349-foot shot to right field.

The Giants responded with two runs in the second inning. Matt Chapman singled with one out, Jung Hoo Lee walked, and both scored on Susac's double to left field.

Stewart struck again with a three-run homer in the bottom of the second following back-to-back walks to Matt McLain and De La Cruz.

Cincinnati moved ahead 8-2 on De La Cruz's one-out homer to center in the fourth. The 442-foot blast was his sixth homer of the season.

Mahle gave up eight runs and eight hits with five walks over four innings against his former team.

Left-hander Brock Burke replaced righty Lowder with two on and two outs in the seventh. Heliot Ramos greeted Burke with a pinch-hit single to score Rafael Devers from third.

Jerar Encarnacion followed with a pinch-hit single to load the bases before Burke struck out Willy Adames on three pitches.

Adames went 0-for-4 with four strikeouts for San Francisco, which entered the game ranked last in the majors in runs (52), home runs (nine) and walks (34).

The Giants were out-hit 10-9 and fell to 1-11 this season when scoring three or fewer runs.
