Four Teams That Must Go All-In at the MLB Trade Deadline

 

July 31 is approaching, and MLB odds are red-hot

 

With just one week remaining until the MLB trade deadline (July 31), several teams are making key decisions: will they sell pieces to rebuild, or buy talent to make a run for glory? From a sports bettor’s perspective, this is one of the most strategic times of the year. Why? Because the moves made now can completely reshape the MLB Odds for the rest of the season. A team that currently looks like a long shot could become a serious title contender tomorrow—and that could mean big wins if you make informed bets.

Here are four teams that should be buyers at the deadline—and how doing so could significantly impact their MLB Lines, especially for savvy bettors.

 

1. San Francisco Giants  – One move away from being feared again

 

  • Current record: 52-45
  • Projected final record: 86-76
  • Division odds: 3.6%
  • Playoff odds: 44.3%
  • Championship odds: 1.3%

 

The Giants already surprised fans this season by acquiring Rafael Devers, a power bat who has instantly upgraded their offense. Just one and a half games out of a wild card spot, the Giants are in a prime position for bettors—especially if they make smart additions.

With Logan Webb and Robbie Ray already anchoring the rotation, the team now needs another reliable starting pitcher and a quality bat to become a deep and dangerous squad, capable of taking on powerhouses like the Dodgers and Braves.

 

Impact on MLB odds:

If the Giants land a difference-maker like Dylan Cease, their MLB Betting  to reach the playoffs—and even win the World Series—could double. Betting on them now, while they’re still at 1.3% for the title, could be high-risk, but with massive upside if their trade deadline goes well.

Key needs: Starting pitcher, second baseman, and a fourth outfielder.

 

2. Philadelphia Phillies – It’s now or never

 

  • Current record: 55-41
  • Projected final record: 93-69
  • Division odds: 66.7%
  • Playoff odds: 93.3%
  • Championship odds: 7.9%

 

With a stellar rotation and sluggers like Bryce Harper and Kyle Schwarber, the Phillies are in full “win-now” mode. But to fully capitalize on their championship window, they must address key weaknesses: the bottom of the lineup, the bullpen, and outfield depth.

Bettors should keep a close eye on this team. If they bring in one or two reliable relievers and a productive outfielder, the Phillies could easily become World Series favorites, with MLB Odds to match.

 

Impact on MLB odds:

With a 93.3% chance of making the playoffs, Philadelphia is a safe mid-term bet—like advancing to the NLCS or winning the National League. If they strengthen the roster, their 7.9% title odds could rise past 12%, according to betting markets.

Key needs: Relievers, center fielder, and left fielder.

 

3. Boston Red Sox  – A surprise team with betting value

 

  • Current record: 53-45
  • Projected final record: 86-76
  • Division odds: 10.1%
  • Playoff odds: 57.3%
  • Championship odds: 2.0%

 

After trading away star Rafael Devers, few expected the Red Sox to be in playoff contention. But thanks to a blend of hungry young players and experienced veterans, they’ve found a winning formula.

With one of the best bullpens in the league and an ace-level starter in Garrett Crochet, Boston now desperately needs another rotation piece and a power hitter who can put fear in opposing pitchers.

 

Impact on MLB odds:

Their current 2.0% championship odds may look low, but if they add an offensive weapon like Pete Alonso or a starter like Marcus Stroman, they could become genuine contenders. Betting on Boston now, while their odds are high, could be a clever long-shot play.

Key needs: Starting pitcher and a power bat.

 

4. Seattle Mariners  – A hidden gem in the Northwest

 

  • Current record: 54-48
  • Projected final record: 87-75
  • Division odds: 16.4%
  • Playoff odds: 68.8%
  • Championship odds: 2.8%

 

The Mariners arguably have the deepest rotation in baseball and a potential 2025 AL MVP in catcher Cal Raleigh. While their bullpen is decent, they could use another trusted lefty reliever to seal close games.

But their most significant issue is offense. Third base and right field have been major weaknesses, and if not addressed, the Mariners could fall short despite a strong core.

 

Impact on MLB odds:

In futures betting, the Mariners offer sneaky value. If they add a bat like Jeimer Candelario or Brent Rooker, their MLB Lines to make a deep playoff run could skyrocket. They’re a perfect dark horse team for bettors.

They’ve already made a move, acquiring first baseman Josh Naylor from the Arizona Diamondbacks. The 28-year-old gives them more offensive depth—something they desperately needed.

Key needs: Left-handed reliever, third baseman, right fielder.

 

What Should Bettors Watch for in This Key Week?

 

As we approach July 31, sportsbooks are continually updating MLB Betting Lines based on trade rumors, recent results, and injury reports. That makes this week critical for futures betting.

If you’re a baseball fan and sports bettor, this is your moment. The moves made at the trade deadline don’t just change rosters—they dramatically shift the MLB Odds. That’s where actual betting value emerges.

The Giants, Phillies, Red Sox, and Mariners all have compelling reasons to make a purchase. If they execute well, these could be the teams filling your pockets come October.
