The Washington Mystics acquired their second center in five days Tuesday when the team traded former first round pick Victoria Dunlap to the Seattle Storm in exchange for eight-year veteran Ashley Robinson.

A 6-foot-4 center, Robinson spent the past five seasons with the Storm and averaged career highs in points (3.8 per game) and rebounds (3.9 per game) in 2011. She won a WNBA championship with Seattle in 2010.

Robinson’s “size, athleticism and shot-blocking ability gives us a new dimension at that position,” Mystics General Manager and Head Coach Trudi Lacey said in a statement. “Ashley brings depth to our team, which is important as we continue to add pieces for a playoff run this upcoming season.”

The Mystics finished 6-28 last season, the second-worst mark in the league. Washington struggled to find ample production in the post to complement all-star forward Crystal Langhorne. The team traded its 2012 first round draft pick for center Nicky Anosike prior to the start of last season in hopes that she could fill that role, but she proved inconsistent and was supplanted in the starting lineup toward the end of the season by veteran DeMya Walker.

On Thursday, Washington signed free agent center Michelle Snow, a 10-year veteran who has averaged 9 points and 6.4 rebounds during her career. Last season, as a member of the Chicago Sky, Snow ranked No. 5 in the WNBA with 1.3 blocks per game. The 6-foot-5 center ranks No. 8 on the WNBA’s all-time blocks list (350).

Dunlap, the 11th overall selection in the 2011 WNBA draft, averaged 2.3 points and 1.7 rebounds per game for the Mystics last season.
