Previous to owning the bar in "Cheers", Sam Malone pitched for which of these Major League Baseball teams?

I remembered Cheers was based in Boston and guessed Sam had loyalty or roots there

as a bostonian literally nobody calls them the BoSox for short

I knew this one but I learned much more as always with this 🎯 game

Mayday Malone

Storied history indeed! Would love to see a game there even though they killed my team in the World Series!
