The St. Louis Cardinals and the Arizona Diamondbacks meet Friday in MLB action from Chase Field. We will look at this from a betting perspective and determine the best bets for this game. Here’s a St. Louis Cardinals vs. Arizona Diamondbacks prediction.
The St. Louis Cardinals did not have a starting pitcher announced at the time that this article was posted. Merrill Kelly will get the start for Arizona here and is 7-8 with a 5.38 ERA and 59 strikeouts this season.
The St. Louis Cardinals come into this game looking to bounce back from their 4-3 loss at the hands of the Atlanta Braves last time out to sit at 50-45 this season. After this series, the Cardinals will head on the road for a set against the Angels.
Jordan Walker leads the Cardinals with 105 hits, 19 doubles, 22 home runs and 74 RBIs while Alec Burleson has 98 hits with 23 doubles, 15 home runs and 67 RBIs. JJ Wetherholt has 91 hits with 13 home runs and 36 RBIs while Ivan Herrera has 86 hits with 14 doubles, 11 home runs and 40 RBIs. Nolan Gorman has 39 hits with 7 home runs and 26 RBIs this season. Masyn Winn’s added 77 hits with 12 doubles and 38 RBIs and Nathan Church has 56 hits with 8 home runs and 28 RBIs this season.
The Arizona Diamondbacks come into this game looking to add on to their 5-3 win over the Dodgers last time out to sit at 49-47 this season. After this series, the Diamondbacks will take on the Athletics at home.
Corbin Carroll has 87 hits including 19 doubles, 10 triples, 13 home runs and 45 RBIs. Ketel Marte has 95 hits with 19 doubles, 17 home runs and 54 RBIs and Geraldo Perdomo has 78 hits, with 13 doubles, 3 triples, 6 home runs and 34 RBIs as well this season. Nolan Arenado also has 75 hits with 17 doubles, 12 home runs and 40 RBIs and Jose Fernandez has 42 hits with 3 home runs and 15 RBIs this season. Ildemaro Vargas also has 72 hits with 13 doubles, 2 triples, 7 home runs and 47 RBIs.
I’m backing St. Louis here. I just think that St. Louis is the better team in this matchup here and even though Arizona has been doing well in that series against the Dodgers, an all-star break or extended break can kill any kind of momentum that a sweep like that brings. St. Louis needs a strong start out of the gate and I think they get it here. Give me St. Louis.
