Stoke City earned their first three points of the season with Harry Clarke and Jacob Brown giving them a deserved Championship victory over Blackpool.
The Seasiders improved in the second half, with Josh Bowler going close to equalising shortly after the restart.
Stoke missed several chances to double their lead before Brown grabbed their second at the near post with 15 minutes remaining.
Dwight Gayle, who joined from Newcastle last month, registered the first effort on goal for the hosts after 13 minutes but Grimshaw was equal to the striker's shot.
Blackpool had to weather plenty of early pressure before Gary Madine sent a glancing header wide and that was the forward's final action in the game as he pulled up with an injury and was replaced by Theo Corbeanu.
