Missouri sports betting preview

The St. Louis Cardinals have the youngest team in baseball after offloading several veterans during the offseason, but they might be ahead of schedule after a 13-8 start. Outfielder Jordan Walker hit six home runs in 111 games last season, but he's already belted eight home runs in 2026 to lead the MLB. St. Louis begins a three-game series in Miami on Monday night, with first pitch scheduled for 6:40 p.m. ET. The Marlins are -136 favorites in that matchup while the Cardinals are +113 underdogs on the money line.

Meanwhile, the Kansas City Royals are off to a sluggish start this season at 7-15, but they're hopeful that a talented young lineup can turn things around to push them back into contention. The latest MLB futures from DraftKings still lists the Royals at +4000 to win the World Series. They'll host the Baltimore Orioles for a three-game series that begins on Monday at 7:40 p.m. ET.
