On May 16, the St. Louis Cardinals defeated the Kansas City Royals 4-2 at Busch Stadium, clinching the second game of the annual I-70 series and securing their first back-to-back sweep of the intrastate rivals since 2019. Alec Burleson’s two-out RBI single in the eighth inning broke a tight contest and gave the home crowd a reason to celebrate, capping a patient two-strike at-bat that showcased the composure the 25-year-old has developed throughout his second full major league season.
Kyle Leahy earned his first career start, working six innings and allowing just two runs while scattering six hits and walking two. The right-hander improved his record to 5-3, transforming from a swingman who spent most of 2023 shuttling between the bullpen and Triple-A Memphis into a legitimate rotation candidate. The win snapped a brief Royals rally that had tied the game at 1-1 in the fifth inning, when Kansas City pushed across their first run against Leahy before the Cardinals’ offense eventually wore down Royals starter Michael Wacha.
Cardinals Capitalize on Home-Field Edge
Cardinals manager Oliver Marmol leaned on the club’s strong home-field advantage, a factor that has kept St. Louis near the top of the NL Central despite early-season inconsistencies. The numbers reveal the team is batting .267 this season while allowing just 3.45 runs per nine innings, a solid differential that fuels confidence and ranks among the top third of National League clubs. Busch Stadium, with its symmetrical 400-foot power alleys and notoriously pitcher-friendly atmosphere, has become a sanctuary for a Cardinals pitching staff that has posted a 3.21 home ERA compared to a 4.18 mark on the road.
Marmol’s strategic decisions paid dividends throughout the contest. After Leahy departed after six innings, the manager turned to his bullpen trio of JoJo Romero, Ryan Helsley, and Giovanny Gallegos to navigate the final three frames. The combination retired seven of the final eight batters faced, with Helsley’s strikeout of Salvador Perez representing the pivotal moment in the eighth inning before Burleson’s heroics at the plate.
Royals Struggle on the Road
Royals road record sits at 6-17, underscoring their difficulty away from Kauffman Stadium, where Kansas City has compiled a respectable 15-10 mark this season. The disparity speaks to a club that has historically performed better in the familiar confines of their downtown ballpark, where the famous fountain beyond the center-field wall provides both psychological comfort and favorable hitting conditions. Kansas City’s offense managed only two runs, both coming on a solo homer by Michael A. Taylor in the seventh, highlighting the gap between the clubs in terms of offensive production during this particular matchup.
Royals manager Matt Quatraro faced difficult decisions in the later innings, choosing to stick with right-hander Lucas Erceg in the eighth despite Burleson’s hot hand. The movebackfired as Burleson, who entered the at-bat 2-for-3 with a sacrifice fly and a run-scoring groundout, delivered the decisive blow. Kansas City’s inability to manufacture runs without the long ball proved symptomatic of a road offense that has scored just 3.2 runs per game outside of Kansas City this season.
Season Context for St. Louis
The Cardinals have won nine of their last twelve games, a surge that lifted them from a mid-division lull to within two games of the NL Central lead heading into their series against the Chicago Cubs. The turnaround represents a testament to the club’s depth and Marmol’s willingness to mix and match lineups based on matchups. Burleson, now batting .298 with eight RBIs in his last ten outings, has emerged as a clutch option after a modest start to the year that saw him hit just .218 through the first month of the season.
The 25-year-old outfielder’s development trajectory has been noteworthy. Drafted by the Cardinals in the second round of the 2020 MLB Draft out of East Carolina University, Burleson spent three years climbing the minor league ladder before making his debut in 2023. His ability to hit for both average and power—he entered the season with 23 home runs in 128 major league games—made him a candidate for a breakout campaign, and the Cardinals are seeing that potential materialize during this critical stretch.
Leahy, a former college standout at Missouri State where he compiled a 3.41 ERA over 45 appearances, spent most of 2023 shuffling between the bullpen and Triple-A before this breakthrough start, giving the rotation a fresh arm as the club eyes a June stretch that features series against the Cubs, Brewers and Mets. His transition from reliever to starter represents a calculated gamble by the Cardinals’ player development staff, who identified the 27-year-old’s stamina as sufficient for a starter’s workload after he logged 78 innings across 40 appearances last season.
Key Developments
- Leahy’s debut start transitioned him from reliever to rotation candidate, a move the front office has hinted at all season. The Cardinals’ starting rotation has dealt with injuries to key arms, making Leahy’s emergence particularly timely.
- Burleson’s first-inning sacrifice fly set the tone for his multi-RBI night, his first sac fly of the year. The opposite-field fly ball to right scored Nolan Arenado from third, demonstrating Burleson’s ability to manufacture runs in situational spots.
- The I-70 series now stands at 2-0 in favor of St. Louis, the first back-to-back sweep since 2019. The rivalry, which began in 1985 when the Royals joined the American League West, has seen the Cardinals hold a 41-39 all-time advantage in regular-season meetings.
- Cardinals closer Ryan Helsley recorded his 14th save of the season, matching his total from all of 2023. The 30-year-old right-hander has emerged as one of the more reliable ninth-inning options in the National League, converting 14 of 15 save opportunities.
What’s Next for the Cardinals?
Following the win, St. Louis improves to 32-22 overall and remains within striking distance of the NL Central lead, trailing only the Milwaukee Brewers and Chicago Cubs in what has emerged as a tightly contested division race. The bullpen’s strong finish bolsters confidence heading into a homestand that includes series against the Cubs and Brewers, two direct competitors in the division standings.
Leahy’s solid debut could earn him more starts, giving the rotation depth as the club navigates a busy June schedule that features 27 games in 30 days. The Cardinals‘ coaching staff will monitor his workload carefully, recognizing that the former Missouri State Bear has never thrown more than 95 innings in a professional season.
According to MLB.com, the Cardinals have recorded 12 runs in their last three home games, a streak that may prove decisive as the playoff race tightens. The combination of timely hitting, solid starting pitching, and a reliable bullpen has positioned St. Louis as a legitimate contender in the National League, though the upcoming stretch against division rivals will serve as the true test of their championship aspirations.
Did Alec Burleson have any other notable hits in the game?
Besides his eighth-inning RBI single, Burleson recorded a sacrifice fly in the first inning and added a run-scoring groundout in the sixth, contributing three of the Cardinals’ four runs. His three-RBI night represented his most productive game of the season and underscored his emergence as a reliable middle-of-the-order threat.
How did Kyle Leahy’s performance compare to his previous outings?
Leahy entered the game with a 0-2 record as a reliever; his six-inning start earned his first win and lowered his ERA to 3.45, a marked improvement over his prior relief appearances. The transition from high-leverage reliever to starting pitcher showcased his versatility and gave the Cardinals exactly what they needed: quality innings that preserved a tired bullpen after a 12-inning victory the previous night.
What is the historical significance of a back-to-back I-70 sweep?
The Cardinals last recorded consecutive I-70 series sweeps in 2019, making this the first such achievement in seven years and underscoring their dominance in the regional rivalry. The I-70 series, which features two games at Busch Stadium and two at Kauffman Stadium, has become one of baseball’s more compelling intrastate rivalries, with both clubs combining for 11 World Series championships and 27 playoff appearances since 1985.
