It's been more than a month since Major League Baseball's trade deadline came and went on Aug. 2. That's enough time for knee-jerk reactions to have given way to first impressions.

So, let's discuss which trades are working out for the best...and for the worst.

We've picked out four deals for each side of the fence. We mostly concerned ourselves with the buyers' perspective, though one particularly disastrous trade—you can probably guess which one—required us to lament how it's working out for all involved parties.

Let's start with some honorable and dishonorable mentions, and then we'll count down the best of the best and the worst of the worst.

 

Honorable and Dishonorable Mentions

Honorable: RHP David Robertson, RHP Noah Syndergaard and SS Edmundo Sosa, Philadelphia Phillies

Robertson has hit a bit of a wall in September, but he still has a 2.76 ERA and five saves in seven tries for Philadelphia. Syndergaard only has a 4.61 ERA as a Phillie, but the team has won five of the seven games he's started.

The big surprise so far is Sosa. He was known for his glovework when the Phillies acquired him, but he's since ripped off a 1.030 OPS. Though this is over a small sample size of 54 plate appearances, it's nonetheless been a boon to the Phillies infield.

Dishonorable: RHPs Tyler Mahle, Jorge López and Michael Fulmer, Minnesota Twins

These guys were supposed to lift a Twins pitching staff that had been inconsistent over the first four months of the season, but that just hasn't really happened.

Fulmer has been more solid than good in their new threads, while López has been hittable in the process of putting up a 4.40 ERA. Mahle, meanwhile, put up a 4.41 ERA in four starts for the Twins before going on the injured list with shoulder inflammation.

Honorable: 3B J.D. Davis, San Francisco Giants

Davis was hitting just .238/.324/.359 through 66 games with the New York Mets, yet his peripheral metrics included some encouraging numbers in the contact quality departments.

As such, it's not the biggest shock that he's upped his slugging percentage to .457 with the Giants. That's more than they were getting from Darin Ruf, who's since slipped even further to a .140/.182/.200 slash line in New York.

Dishonorable: C Christian Vázquez and DH Trey Mancini, Houston Astros

Vázquez has hit just .246 in 22 games as an Astro, and it's an empty .246. He's walked only four times and has yet to record an extra-base hit.

For his part, the seven home runs Mancini has given the Astros are all well and good. But he also has just 14 other hits in 102 at-bats, with 33 strikeouts to boot.

 

Best No. 4: Chris Martin Has Dominated as a Dodger

The Trade: Los Angeles Dodgers get RHP Chris Martin; Chicago Cubs get INF/OF Zach McKinstry

Look, a team simply can't win 96 of its first 139 games without some kind of Midas Touch. Of all the players to be turned into gold by the Dodgers this season, Chris Martin is merely the latest.

After pitching to a modest 4.31 ERA through 34 appearances as a Cub, the 36-year-old veteran has surrendered only four earned runs over 16.2 innings as a Dodger. That comes out to a 2.16 ERA, though he arguably deserves better on account of how he's allowed only nine hits next to zero walks and 20 strikeouts.
