Brewers Trying to Lock Down NL Central Crown

Milwaukee lost for just the second time in seven games as they were drubbed in the opening game of the set Friday night. The Brewers entered Friday 94-60 and held a six-game lead over the Cubs in the NL Central. Against St. Louis in the series opener Friday, Milwaukee finished with 12 hits as Jake Bauers paced the team with three, while Jackson Chourio and Christian Yelich each had two in the game. Sal Frelick hit his 12th homer of the year in the contest. The Brewers were zero of eight with runners in scoring position and left 12 men on base in the game. Jacob Misiorowski (5-2) took the loss as he allowed two runs on five hits with three walks and three strikeouts over 3.2 innings of work.

Freddy Peralta gets the ball for Milwaukee here as he makes his 32nd start of the season in this contest. He is 17-6 with a 2.65 ERA, a 1.073 WHIP, 65 walks and 195 strikeouts over 169.2 innings of work this season. Peralta earned the win in his last start, which came Tuesday at home against the Angels.

St. Louis Shooting to Play Spoiler

Brewers vs. Cardinals Pick

Moneyline Pick for Brewers vs. Cardinals

  • Brewers (4 units)

While St. Louis took the opening game of this set Friday night, it’s not all that often that the Brewers are going to go zero for eight with runners in scoring position or leave 12 runners on base. Peralta has been solid all season and Milwaukee is trying to lock down the top seed in the NL playoff picture. Liberatore has pitched well against Milwaukee in his career but the fact remains that the Cardinals are in a spoiler role at best at this stage of the season. The Brewers are an explosive team, especially on the road, and they should find a way to prevail here to take another step toward their goal.

Over/Under Pick for Brewers vs. Cardinals

  • Under (4 units)

Milwaukee has seen the over post a 75-74-5 mark in their 154 games in relation to the total this season entering Saturday. The Brewers are tied for 2nd in the majors in runs per game with 5.10, and that number climbs to 5.43 runs per game on the road. Milwaukee has seen an average total of 9.01 runs per game this season, and that number climbs to 9.50 runs per game away from American Family Field on the year. St. Louis entered Saturday having seen the over post a 77-69-8 mark on the season. The Cardinals are 18th in the majors by averaging 4.29 runs per game on the season, a number that stays flat at 4.29 runs per game at home. St. Louis gives up 4.62 runs per game overall, a number that drops to 4.28 runs per game at home on the year. That gives the Cardinals an average total of 8.91 runs per game, which tumbles to 8.57 runs per game as the home team. We saw eight runs in the opener, and with Peralta on the bump here, this game likely falls short as well.
