David Robertson, CHW – In terms of closers, Robertson has the fifth highest SOBB at 27.8, which ranks 13th for all relievers. This is a great improvement from last season when Robertson had a 16.1 SOBB thanks to a 12.0 BB%. In fact, this year’s mark is in line with his 2014-15 seasons and representative of Robertson’s true ability. Robertson had a SwStr% of 12 percent or better over the past three seasons as well, and it’s jumped to 16.1 this season thanks to MLB hitters being more aggressive. Robertson will have no problems carrying his success no matter where he lands at the trade deadline. As for his replacement, Tommy Kahnle is likely the answer, posting a 37.3 SOBB. That mark is only behind Craig Kimbrel and Kenley Jansen, and it shows just how dominant Kahnle can be.
