Dwarf hamster with gray fur, white patch

I lost my tiny dwarf hamster yesterday around 3pm in the Parkersburg-Marietta area. He’s about the size of a ping-pong ball, with gray-brown fur and a small white patch on his left ear, plus a cream belly. Last seen near the Market Street entrance to City Park, by the gazebo behind the fountain, in a clear plastic cage with a blue wheel. He’s gentle and curious, and this little guy has sentimental value for my family—especially my 4-year-old daughter. If you’ve seen him, please reach out; I’d really love to have him back.
