The St. Louis Cardinals (67-51, 66-52 RL, 55-59-4 O/U battle the Arizona Diamondbacks (55-64, 69-50 RL, 51-63-5 O/U) in the three-game series finale on Sunday afternoon. The Cardinals send Jose Quintana to the mound. The Diamondbacks reply with Merrill Kelly, seeking his first win of the month. The Cards lead the season series 4-2.

Quintana Starts, Cards Stay Hot

Jose Quintana will be on the hill for the 24th time of the season on Sunday. Quintana has been effective since joining the Cardinals. He limited the Rockies to only two runs on four hits in five innings last time out. The veteran left-hander features a 2.65 ERA this month and has filed a 3.38 ERA and a 1.24 WHIP to go with a 4-5 record in 120 innings of work on the season. Quintana has yet to pitch against Arizona this season and has allowed 20 runs in 21 career innings against the foes. 

The Cardinals have been one of the most consistent teams this month. They have won eight out of their last ten games to build a four-game ahead of the Brewers. They recorded a dominating sweep of the Rockies prior to this series propelled by a barrage of runs. 

Paul Goldschmidt continues his MVP-caliber season. The 34-year-old first baseman has launched five homers along with 12 RBIs in his last eight games. Goldschmidt now has 30 big flies with 96 RBIs and a 1.056 OPS. He is 7 for 15 with six RBIs against the D-Backs this season.

The Cards are posting an average of 4.76 runs, ranking them fourth overall. The pitching staff has recorded a 3.81 team ERA, good for 12th in the big leagues.

Kelly Resumes Dominance in Another Stellar Outing

The D-Backs will have Merrill Kelly on the hill in the series finale. Kelly was outstanding in his previous start, completing seven shutout innings against the Giants, leading to a no-decision in a game Arizona lost by a 2-1 score. The veteran right-hander has been incredible, allowing a total of only five runs in his last five starts, and is sporting a stifling 2.81 ERA and a 1.12 WHIP to go with a 10-5 record in 144.1 innings pitched. Kelly tossed six scoreless innings in a 2-0 win against the Cards earlier this season and is 2-1 with a 3.00 ERA in three meetings against the foes.

Arizona went a solid 4-3 on a seven-game road trip before this series including two wins against the Giants. The pitching has been their top strength recently. The D-Backs are 3-2 in their last five home bouts after losing the series opener to the Cards by a 5-1 score.

Dalton Varsho is having a promising season and continues to excel, posting a .790 OPS on the month. The 26-year-old now has 16 homers along with 56 RBIs and a .733 OPS. Varsho is 4 for 17 with one RBI against the Cardinals. Ketel Marte is questionable for this game.

The Diamondbacks are scoring an average of 4.25 runs, landing them at 18th overall. The pitching staff is carrying a 4.07 team ERA, placing them 21st in the Major Leagues. 

Best Bets for this Game

Full-Game Side Bet

Insiders Status:


The Cardinals are not a great road team. They lost their previous road series to the Rockies and are now two games below .500 on the road. The Diamondbacks are tough to beat at Chase Field. They have posted an 8-4 record in their last 12 home games. 

Furthermore, Cards’ starter Jose Quintana has struggled against the Diamondbacks throughout his career, surrendering a whopping 20 runs in 21 innings. Quintana has posted a poor 4.93 road ERA on the season. D-Backs’ starter Merrill Kelly has quietly been spectacular. The right-hander recorded a minuscule 1.31 ERA last month and a 2.37 ERA in his three performances this month. He features a strong 3.00 career ERA against the Cards.

Prediction: Arizona Diamondbacks +116

Full-Game Total Pick

Insiders Status:


I am going with the over here. The Cardinals' bats are hot and should generate runs, especially late in the game after Kelly has exited against a poor bullpen. They have scored at least five runs in six consecutive games.

In addition, the Cards have squandered a whopping 37 runs in their last five road games. The Diamondbacks' offense is fine. They have averaged 4 runs in their last ten games including 21 runs in their last four home clashes. The over is also 7-3 in the Diamondbacks' last 10 home games.

Prediction: Over 7.5
