Grimes ended with nine points (3-5 FG, 3-5 3Pt), one rebound and one steal across 12 minutes during Tuesday's 120-114 win over Minnesota.
Grimes entered Tuesday's contest having missed his first three three-point attempts of the season. The 24-year-old has the upside to become a consistent shooter in the Mavericks' offense, but his role will be inconsistent if his shot isn't falling.
