Cardinals Bring Winning Form into Kansas City

St. Louis enters Thursday's contest with a 40-31 overall record and a strong 19-15 road record. The Cardinals have won three of their last five games, recently winning over San Diego by scores of 3-2 and 3-0.

Overall, St. Louis has been playing competitive baseball and enters this matchup with momentum from consecutive victories.

One of the Cardinals' biggest strengths has been their ability to generate offense consistently. St. Louis owns advantages over Kansas City in batting average, runs scored, home runs, on-base percentage, slugging percentage, and ERA. Those numbers have helped the club maintain one of the better records in this matchup.

Royals Hoping to Defend Home Field

Kansas City comes into this game with a 29-45 overall record and a 17-21 record at home. The Royals have won just one of their last five games, recently defeating Houston 4-0. They also recently lost to Washington twice and dropped two games against Houston. While the recent results have been challenging, Kansas City will look to use home field to turn things around.

The Royals are batting .242 with 295 runs scored, 599 hits, and 65 home runs. Kansas City owns a .317 on-base percentage and a .378 slugging percentage. Their pitching staff has posted a 4.51 ERA and a 1.38 WHIP while allowing opponents to hit .252. The Royals have also recorded 583 strikeouts and issued 281 walks.

The biggest advantage for Kansas City entering this game is the projected starting pitcher. While the team numbers favor St. Louis in several areas, Kansas City's starter owns the lower ERA, lower WHIP, fewer walks, and fewer home runs allowed. That could help keep the Royals competitive in a matchup where they trail statistically in many categories.

St. Louis Cardinals vs Kansas City Royals Picks and Prediction

St. Louis Cardinals vs Kansas City Royals Pick

  • Pick: St. Louis Cardinals Moneyline

Even though the matchup predictor slightly favors Kansas City, St. Louis owns the better overall record, better road record, and stronger numbers in most major team categories. The Cardinals have also won three of their last five games compared to one victory for the Royals during the same span. The overall team profile points toward St. Louis having the edge.

St. Louis Cardinals vs Kansas City Royals Total Pick

  • Pick: Over 8.5

Take the over if the total is set at 8.5. I like the over because both projected starters enter with ERAs above 4.00, and both teams have combined for 148 home runs this season. St. Louis has scored 325 runs this year, and Kansas City has shown the ability to contribute offensively as well. The pitching numbers suggest opportunities for runs on both sides.

Final Score Prediction: St. Louis Cardinals 5 – Kansas City Royals 4
