The Golden State Warriors have added Brad Wanamaker to their roster after agreeing to terms on a one-year, $2.25 million deal.

Originally going undrafted in the 2011 rookie selection, Brad Wanamaker played extensively overseas, as well as in the NBA's development league. He joined the Boston Celtics on a one-year contract in 2018, paving the way for him to carve out a role in Brad Stevens' rotation and earning another one-year extension in 2019.

Averaging nearly 20 minutes a game during the past season, Wanamaker made a name for himself as a high-effort type player, whose defensive instincts and floor-spacing abilities proved vital to Boston's depth along the perimeter. In 71 games during the season, Wanamaker averaged 6.9 points, 2.0 rebounds and 2.5 assists while shooting 44.8 percent from the field and 36.3 percent from deep and 92.6 percent from the free-throw line.

With the Warriors, the University of Pittsburgh product will primarily serve as the backup to point guard Stephen Curry. He is also expected to provide wing depth for a franchise that is still reeling from the loss of Klay Thompson.

The free-agent signing is the first of the offseason for the Warriors, though the team did also draft big man James Wiseman second overall in Tuesday's NBA Draft. The team is still predicted to pursue other free agents to bolster their rotation.

As for the Celtics, Wanamaker is the third player that they have lost from the rotation last season. With Gordon Hayward receiving a lucrative contract with the Charlotte Hornets and Enes Kanter being traded to the Portland Trail Blazers, the franchise will look to retool with the extra cap space. Not long after the announcement of Wanamaker's deal with the Warriors, Boston announced they had signed center Tristan Thompson.
