MLB odds, lines, picks: Advanced computer model includes the Phillies in parlay for Wednesday, August 21 that would pay nearly 9-1

The Milwaukee Brewers are the only team in baseball that has opened up a double-digit lead in their respective divisions. On Wednesday, they'll look to take another step towards winning the NL Central when they take on the St. Louis Cardinals. Milwaukee's magic number is 26 but the tightest divisional race is in the AL East, where the Baltimore Orioles lead the New York Yankees by a half-game. Both have tough Wednesday matchups, with the Orioles visiting the Mets and the Yankees hosting the AL Central-leading Guardians.

Milwaukee is a -106 underdog against St. Louis according to the latest Cardinals vs. Brewers odds. Meanwhile, the Yankees are -189 favorites and the Orioles are +112 underdogs in Wednesday's MLB odds. However, those are just three of 15 games on the packed MLB schedule for Wednesday.
