Top 20 Most Impactful Acquisitions of 2018

3. J.D. Martinez

Prior to the 2018 season, the Boston Red Sox signed J.D. Martinez to a hefty five-year $110 million contract. Martinez was definitely worth it though, as he hit .330 with 43 home runs and a league-leading 130 RBI.

Martinez would add 14 more RBI in the postseason, as he led the Red Sox to a World Series title.
