Coming in at No. 4 on this year's list are brothers Sam & Seth Levinson, whose Brooklyn-based baseball agency ACES has negotiated more than $1.3 billion in Major League Baseball contracts, including the most free-agent multi-year deals in the last decade (with $266 million in 2016-17 alone). The Levinsons have earned themselves more than $65 million in commissions (up a cool $10 million from last year) while building one of the biggest single-sport representation practices in the industry. Among their biggest deals are Jon Lester's six-year, $155 million contract with the Chicago Cubs (signed in December 2014) and David Wright's eight-year, $138 million deal with the New York Mets (struck in November 2012). This past off-season, the Levinsons negotiated Danny Duffy's five-year, $65 million contract with the Kansas City Royals and Josh Reddick's four-year, $52 million deal with the Houston Astros.
