Now she has a chance to demonstrate her improvement against a Washington Mystics club she struggled to score against last season.
Robinson will try to help the Stars post a fourth straight victory Tuesday when they look to hand the stumbling Mystics a fifth consecutive defeat.
Washington (5-9) won last season's two meetings by an average of 16.0 points thanks to balanced scoring, as no player scored more than 14 points in either contest.
San Antonio (7-6) was led by Jia Perkins' 17.0 scoring average in those games as Robinson struggled to total 12 points on 6-of-18 shooting, although the playmaking guard had 17 assists.
Robinson figures to fare better from the floor now since she is averaging a career-high 14.1 points while ranking third in the WNBA with 5.8 assists per game. She led the league with 6.7 assists per game in 2013 but has become more of a scoring threat in her fourth season.
''She's always had great quickness, and she was very well-coached in college,'' coach Dan Hughes said. ''But now she's learning to make the right basketball play, and she's increased her ability to shoot the basketball. So this is just not a quick player that penetrates and dishes and dumps.''
Robinson came through in the clutch Sunday in a 72-69 win over Los Angeles. She tied the game with 40 seconds left and added a driving layup with 8.4 to go that proved to be the difference.
San Antonio will also have Becky Hammon available Tuesday after the veteran guard did not play in either meeting with the Mystics last year.
The 37-year-old Hammon is nearing the end of her career, but she's scored in double figures in every game of this win streak with 11 points Sunday.
''Obviously Becky's a vet,'' Robinson said. ''To have her presence out there is really nice."
San Antonio will get its first look at a young Washington team in which rookie Bria Hartley has emerged as the leading scorer with 11.1 points per game. The UConn product scored a season-high 26 points in Sunday's 89-86 overtime loss to Seattle.
''She's fantastic,'' veteran Mystics guard Kara Lawson said. ''Forget that she's a rookie. She really doesn't have many weaknesses and is really good at every phase of the game."
The Mystics could use a change in fortunes from Hartley's backcourt mate. Ivory Latta is averaging 6.7 points in her last seven games after averaging 14.1 in her first seven.
