RotoExperts announced the acquisition of FantasyAuctioneer.com on Tuesday morning, the first full day of the Fantasy Sports Trade Association winter business conference, a source has told FSB.com.

Fantasy Auctioneer has been online since 2004 and specializes in auction draft hosting, software and contests. The site won the 2005 FSTA award for best new website and took home the plaques for best draft-style contest and specialty product a year later. It’s business partners have included league-hosting sites RealTime Sports and MyFantasyLeague, as well as many content outlets.

The acquisition follows RotoExperts’ December purchase of Diamond Draft and appears to be in line with the company’s stated goal of adding software and services to its fantasy content.

In announcing the Diamond Draft deal, RotoExperts founder Ben Ice said: “Fantasy drafting software has been an interest of our leadership team since the origins of the company. After building a custom application for the NFL season, we decided that it would be most efficient to acquire an existing product heading into the upcoming fantasy baseball season.”

The same logic would seem to apply in acquiring arguably the Web’s best-known auction tool. Why start from scratch when you can align with an established brand?
