The MLB regular season is more than two months old, past the one-third mark, but not quite to the All-Star break. Compared to preseason expectations, a few teams have been surprises and a few others have been disappointments.The Los Angeles Dodgers and New York Yankees were preseason favorites who have more or less lived up to the hype so far. The Dodgers remain World Series favorites at +190 and the Yankees are second in the odds at +550. No major movement there.The Tampa Bay Rays and Milwaukee Brewers are surprise division leaders who are gradually climbing the futures board. Then there are the struggles of the Toronto Blue Jays, Boston Red Sox and the much-maligned New York Mets.Let’s take a look at which teams have made the biggest moves in futures odds, for better or for worse, since the start of the season.Brewers, Rays on the riseCongratulations to every Milwaukee Brewers believer who bought in early. A +3000 preseason dark horse, Milwaukee is now a top-five contender at +1500 thanks to the scariest starting tandem in baseball at the moment.Jacob Misiorowski and Kyle Harrison are tearing through lineups like tissue paper, combining for a 14-3 record with 193 strikeouts thus far. Harrison got shelled Monday against the Athletics, but before that the Brewers were the first team in more than 100 years to have a pair of pitchers with ERAs under 2.00 who both average 11 or more strikeouts per nine innings through 10 starts.The concern with the Brew Crew, as always, is offense. For now, the bats are delivering. Milwaukee is tied for third in baseball in runs scored.If you boarded the Dodgers or Yankees train early, everything is running right on schedule. The Dodgers are clear favorites at +190, up from a +220 mark before the season started, with a 7.5-game lead in the NL West. The Yankees, while a far-off second at +550, have still cut their odds nearly in half from their preseason 10-to-1 mark thanks to a 29-17 record since a sluggish 10-9 start.The Yankees’ steady play has them trailing the Rays in the AL East only by percentage points, whose brutal 4-10 stretch over the past couple of weeks pushed them out of the top five in the odds. But given that the Rays are +2200 after their herky-jerky performance over the last month, they still could be a sound investment. Remember, they were +10000 preseason, and +6600 as recently as May 1. If you bought in on Tampa, these are the waves you have to ride.East teams falling down the boardThree teams, one in the NL East and two in the AL East, among the top seven of the preseason odds to win the World Series have dropped down the board. The Blue Jays and Red Sox have shattered the hearts of early investors. The AL East pair came into the season with World Series odds of +1600 or shorter and have seen their stocks tumble.The Red Sox fired everyone with a pulse and remained mediocre. The Blue Jays have one qualified starter slugging better than .450. Both rosters are talented enough to rip off a tremendous second half, but as of this moment it’s hard to bet on it.And then there are the Mets. Third in World Series odds to open the year (+1200), now at +8000. Ranked 28th in batting average (.230), 29th in OPS (.661) and in last place in the NL East.If you are a buy-low investor, it probably doesn’t get lower than this. Maybe they can pull off what Cleveland did a year ago, but even those Guardians burned themselves out before ever reaching the World Series, much less winning it.Interesting contenders to watch forSpeaking of that NL East, the Atlanta Braves are nine games ahead of everybody in the division and are up to third in World Series odds (+900). Their pitching staff has allowed the second-lowest WHIP and second-lowest batting average, and their offense boasts the third-best batting average and OPS.The Braves’ problem, as always, is Los Angeles. Atlanta would be the undisputed best team in baseball at the moment if not for the Dodgers, and the NL pennant road runs through LA, so the Braves are always going to have a speed limiter on their World Series odds.Every bit of their infrastructure shows they are built to challenge the kings.In the American League, the Seattle Mariners’ odds haven’t buckled despite a scuffling start. They’re a breath over .500, but still sit at +1000 to win it all, an improvement from their +1300 preseason mark. Their offensive engines from a year ago have struggled to fire, but the soft division and belief in positive regression have maintained their odds thus far. It’s hard to imagine these numbers hold much longer if anyone in the AL West wakes up, but if Cal Raleigh, Julio Rodríguez and Josh Naylor snap into shape in the second half, +1000 could be a fond memory of a bargain-bin price for the AL’s top challenger to the Yankees in the odds.The NL Central is full of teams that ebb and flow, and most squads in the division can look like the best team in baseball one night and a Triple-A unit the next. If you’re a long-shot artist, any of the Pittsburgh Pirates (+4000), Chicago Cubs (+2000) or St. Louis Cardinals (+12500) could be on your bet slip — so long as you are willing to ride out the highs and lows.But if you are chasing an adrenaline high from here on out, it’s time to consider riding the Chicago White Sox at +8000.Using the Mariners as an AL comparison point, the White Sox have racked up more homers, a better team batting average and a better OPS. Rookie Munetaka Murakami certainly has been the driving force behind that surge, but the team has scored 46 runs in the eight games since he went on the IL with a hamstring injury.Their pitching staff remains too volatile to value their long-term prospects with any certainty, but any team that can shell opposing defenses the way the Sox can warrants attention, especially at +8000 in a weak division and a vulnerable American League.
