15 games played, by sport.
MLB The marquee tilt tonight is Tampa Bay against Atlanta at Truist Park, first place in the AL East essentially separating these two clubs by a game as they chase the heart of a stacked September. Keep an eye on Milwaukee hosting the Cubs too, since the Brewers are running away with the best record in baseball and Chicago needs the bullpen to hold up on the road to stay in the wild card mix. Also watch Houston jumping out early on Philadelphia's ace, a reminder that a starter who doesn't get into his stuff early can turn a getaway day into a laugher fast.
MLS The marquee slate item is Inter Miami CF at Chicago Fire FC, where Miami's high-powered attack heads to Soldier Field against a Chicago side that has quietly put together a solid season and will look to grind out a clean sheet at home. Also worth watching is Nashville SC visiting Toronto FC, with Nashville riding one of the league's best records and hoping to avoid a letdown against a struggling Toronto squad. Keep an eye on LAFC hosting Red Bull New York too, since LAFC enters as heavy favorites and a sitter in front of goal could turn a comfortable night into a nervy stoppage-time finish.
NFL The marquee game is Thursday night in Seattle, where the Seahawks host the New England Patriots to open the season, with Seattle favored by 3 and the total sitting at 44.5. Both teams are 0-0, so there's no playoff math yet, but it's an early measuring stick for whether New England's offense can move the ball against a tough Seattle defense at Lumen Field. Watch how Seattle handles the line of scrimmage early — if they control time of possession and force New England into third-and-long all night, this could get out of hand before the Patriots ever sniff the red zone.
