Mariners add a free agent: Tucker, the clubhouse dog
“He got scouted very heavily,” Servais said. “We ran people in there, and we cross-checked them. Jack ran in there. We got big-time numbers on this dog. So he went high in the Draft. We're happy to have him as a free-agent addition to our club. Really good. This guy will fetch and play with the guys all day long. You'll see him out here running around the field here the next few days. He's got the clubhouse covered right now.”
