Mariners broadcaster Dave Sims eager to promote awareness after surgery for prostate cancer

Dave Sims has no plans to keep quiet.

As the Mariners’ play-by-play man on their television broadcast for the past nine seasons, silence isn’t something that occurs often around him. A renaissance broadcaster experienced in calling baseball, basketball and football games at the highest level, Sims will discuss any sports subject — and plenty outside of sports — with a comfortable ease.

But Sims has something else he wants to discuss this baseball season and beyond.

The subject: Prostate cancer.

Why? Because Sims now is a prostate cancer survivor.

After taking a physical in September, doctors noticed that Sims’ prostate-specific-antigen (PSA) numbers were elevated.
