They played a friendly against INAC Kobe Leonessa, who were sufficiently impressed with her to offer her a contract in April 2012.

In December 2013, Yanez signed with Seattle Reign FC on loan from INAC Kobe Leonessa for the second season of the National Women's Soccer League.

Of the signing, Reign FC head coach Laura Harvey said, "We immediately knew that Bev would be a massive addition to our club, so we made it a priority to find a way to bring her to Seattle for the 2014 season.

Yanez scored the game-opening goal in the 71st minute after subbing in following a hip strain injury that had kept her from the pitch for a few games.

[30] Yanez, along with teammates Lauren Barnes, Kim Little, and Jess Fishlock, were named to the NWSL Best XI team.

[2] On November 14, 2016, Reign FC announced that Yanez would be loaned to Australian club Melbourne City for the NWSL off-season.
