Kansas City Royals

On August 30, 2025, the Kansas City Royals host the Detroit Tigers at Kauffman Stadium in a crucial American League Central matchup. The Royals, currently sitting at 69-66, are having an average season, while the Tigers boast a strong 79-57 record and are positioning themselves well for the stretch run. In their last game, the Tigers triumphed over the Royals, signaling a need for Kansas City to turn things around quickly to close the gap.

Kansas City is projected to start Stephen Kolek, who has had a challenging season with a 4-5 record and a 4.18 ERA. He ranks as the 183rd best starting pitcher in MLB according to the leading MLB projection system, making him one of the weaker arms on the mound. The projections suggest Kolek will average 5.1 innings while allowing around 2.7 earned runs, but he struggles with his command, averaging 1.6 walks per game, which could be problematic against a disciplined Tigers lineup.

Opposing him will be Jack Flaherty, who, despite a disappointing 7-13 record, is expected to pitch 5.3 innings with a strikeout rate of 28.4%. Flaherty’s 3.66 xFIP indicates he may be due for better fortune, and he will face a Royals offense that has struggled, ranking 23rd overall. However, he could face challenges with the Royals’ low strikeout rate, making this a potentially favorable matchup for Kansas City.

With a game total set at 9.0 runs, the betting markets are hinting this could be a close contest. The Tigers have a slight edge with their moneyline at -125, reflecting their superior season thus far, but the Royals do have the potential for an upset, especially if Kolek can outperform expectations on the mound.

Detroit Tigers Insights

• Jack Flaherty – Over/Under 4.5 Strikeouts (-120/-110)
  Jack Flaherty’s fastball velocity has dropped 1.1 mph this season (92.2 mph) below where it was last season (93.3 mph).
  Explain: Velocity is a key component to fastball success in generating strikeouts and preventing runs, so a pitcher whose velocity decreases will likely see worse results.
• Spencer Torkelson – Over/Under 1.5 Total Bases (+130/-170)
  Extreme flyball bats like Spencer Torkelson usually hit better against extreme groundball pitchers like Stephen Kolek.
  Explain: This mostly has to do with the way the hitter’s swing plane interacts with the pitch trajectory, and it can create boosted performance across all categories and hidden value few are considering.
• Detroit Tigers – 2H Moneyline
  The Detroit Tigers bullpen grades out as the 7th-best in MLB, according to the leading projection system (THE BAT).
  Explain: Most bettors only consider the starting pitcher, but a strong bullpen sneakily creates a tougher matchup for the opposing offense and suppresses a game’s runs.

Kansas City Royals Insights

• Stephen Kolek – Over/Under Pitching Outs
  Stephen Kolek has recorded 17.1 outs per start this year, grading out in the 80th percentile.
  Explain: A pitcher who averages more outs per start than his Outs prop may be a good bet to go over, and visa-versa for the under.
• Vinnie Pasquantino – Over/Under 1.5 Total Bases (+135/-170)
  Vinnie Pasquantino has made significant strides with his Barrel% of late, improving his 10.1% seasonal rate to 24.3% in the last two weeks.
  Explain: Barrel% measures how often a player hits the ball at the optimal exit velocity and launch angle and is a terrific measure of underlying power.
• Salvador Perez – Over/Under 1.5 Total Bases (+130/-170)
  Salvador Perez pulls a lot of his flyballs (36.9% — 95th percentile) but may find it hard to clear MLB’s 4th-deepest LF fences in today’s matchup.
  Explain: This player’s skill set does not match up particularly well with the park he’s in today, which may lead to worse-than-usual performance.
