3 rentals the Mariners could Use to restock the bullpen

Option #2: Paul Sewald

Imagine if the Mariners got their old closer back? Sewald hasn't been healthy for a good portion of the year but has a 2.57 in 31 regular season games for the Snakes. Paul is a prime example of the Seattle pitching lab, with a 5.50 career MLB ERA with the Mets in 125 appearances before closing 52 games for the Mariners over a three-year period. Sewald has a two-pitch mix, a 91 MPH four-seam, and a sweeper. He's a non-traditional closer without a big fastball similar to the Yankees closer, Clay Holmes. It may not be en vogue, but a closer needs to get outs. Who cares if the four-seam is 91 or 98, right?

If the Diamondbacks continue to fall down the Wild Card ladder, there's really no way Sewald stays in Arizona. Too many contenders will bid for his services, as guy with 9th inning experience who doesn't have a huge salary figure. Last year, he had a 30%+ K rate on both pitches, but that sweeper is what really makes Sewald special as a reliever. This is Paul's year to test the market, so he has a chance for a nice payday if he can show flashes of dominance down the stretch. What better place for the occasion than the park where he made himself a brand name reliever?
