At times, during commentary, commentators speak sentences like "Playing well, Victor is", "A great player, Steven was".
It's grammatical but it's "marked", meaning that this word order isn't the normal declarative order but is chosen intentionally to create emphasis. Even then, it isn't usual, and I'm surprised by your implication that commentators are using it frequently. However, sometimes this order is used for humorous effect, as it reflects the sentence construction of the character Yoda in the Star Wars movies.
Your punctuation is correct.
