The lead is still 4 games, and Cleveland is off today, so even if the Twins lose today vs Washington *and* get swept in Cleveland, we'd still be a half-game ahead on Monday morning. Although I doubt anyone would feel too confident at that point, regardless of a half-game lead! The earliest the Twins could technically be tied for 1st place would be Tuesday morning. Oakland is only a half-game ahead of Cleveland (or, 3.5 back of the Twins), and Tampa is only a half-game ahead of them (3 back of the Twins). While it's possibly for a team to make up a 4 game deficit over ~15 games, it's not likely -- and it's even more unlikely that multiple teams would make up a 3-4 game deficit over ~15 games. Fangraphs still has us 95.2% to win the division, and 99.2% to make the playoffs.
