You could say a month is too short a sample size to judge the deals at this season’s trade deadline. Many of the prospects moved won’t be ready to make an impact until years from now.

But the purpose of the bigger trades was for immediate help, to strengthen current playoff teams — along with those on the fringe of contention — for an October push. Viewed through that lens, a month is plenty of time to see how those clubs have fared with their deadline decisions, whether they pulled the trigger or chose to pass.

Based on that criteria, here’s a look at some of the more active teams on Aug. 2, what those additions have done for them  as well as how those clubs performed with those players on board. And because the impact can be subjective to some degree, we’ve ranked them by record from the 6 p.m. deadline on Aug. 2 through Friday’s games.
