Cardinals vs Royals Expert Picks & Player Props to Bet (June 21)

• The Cardinals and Royals wrap-up their three game series today in Kansas City
• Jordan Walker and Alec Burleson offer immense value in the total bases market away

The St. Louis Cardinals (40-34) conclude their series as road favorites in the MLB odds today, looking to avoid being swept by Kansas City Royals (32-45). First pitch is set for 2:10 PM ET at Kauffman Stadium, with the MLB weather forecast calling for a chance of thunderstorms and mid-70’s temperatures.

The Cardinals bring a potent lineup featuring elite bats like Jordan Walker. Meanwhile, the Royals rely heavily on the veteran presence of Salvador Perez to generate run support. I don’t see a ton of value in either side or total, but there’s a lot of things to like about the player props market. Keep reading to see my favorite Cardinals vs Royals expert picks and player props to bet for June 21, below.

When hunting for value in the MLB props, the top of the home run board is heavily populated by power threats from both dugouts. Walker leads all sluggers with +373 odds to light the lamp, while Kansas City’s Carter Jensen (+392) trails closely behind.

Sportsbooks are making bettors eat heavy juice on several prominent hitters to record a simple base hit. Masyn Winn is priced at a staggering -253 to cross the 0.5-hit threshold. I prefer looking at higher totals like Burleson or Ivan Herrera, whose odds of securing a multi-hit game sit at +163 and +157, respectively.

Dustin May vs Stephen Kolek Stats

On the mound, Dustin May draws the marquee pitching lines. The right-hander has a strikeout total set at 5.5, with sportsbooks heavily leaning toward the Under at -151. His total outs prop sits at 17.5, asking him to finish at least six frames to cash the Over.

Stephen Kolek is facing incredibly modest expectations. His strikeout total sits at a flat 3.5, with both sides priced tightly. The books clearly respect his lack of swing-and-miss stuff in this spot.

Cardinals vs Royals Expert Picks and Player Props to Bet

When evaluating the MLB starting lineups data for this matchup, a few clear edges immediately jump off the page. The St. Louis offense has been reliably producing on the road, presenting excellent value in the total bases market. Meanwhile, Kansas City’s pitching situation points toward a brutal low-strikeout environment for their starter.

Here are my top three actionable player prop predictions to target:

Pick 1: Jordan Walker Over 1.5 Total Bases (-102 at Bet365)

Walker is 8-4 versus a total bases line of 1.5 over his last 12 games, giving me a 67% success rate. His numbers get even better away from home. Walker has gone over 1.5 total bases in 4 of his last 5 road games per the MLB batter vs pitcher stats. In a favorable matchup against a low-strikeout pitcher, he will get plenty of at-bats to smack an extra-base hit and avoid grounding into a double play.

Pick 2: Alec Burleson Over 1.5 Total Bases (-104 at DraftKings)

Continuing the trend of St. Louis batters thriving outside their home park, Burleson is an absolute must-bet. He has exceeded 1.5 total bases in 8 of his last 10 away games, hitting at a staggering 80% cover rate. Burleson averages a massive 2.9 total bases per game on the road during this stretch.

Pick 3: Stephen Kolek Under 3.5 Strikeouts (-117 at DraftKings)

On the bump, the data aggressively screams to fade Kolek’s arm. He has failed to exceed 3.5 strikeouts in 13 of his last 14 games overall. His strikeout potential has completely fallen off a cliff. The home crowd hasn’t helped either, as Kolek has stayed under 3.5 strikeouts in 13 of his last 14 home games. He averages a meager 3 strikeouts per outing at Kauffman Stadium. Lock in the Under.
