One of the more pressing questions for the Mariners early in the offseason will be whether to pick up Denard Span‘s $12 million option. In about a half season, he provided the Mariners with 0.9 fWAR/1.0 rWAR/1.3 WARP, and at that level, he would be somewhat affordable. However, considering his age and surprising success against LHPs, he may not be a good bet to sustain that level of performance while Ben Gamel has done his best to legitimately improve this year.
Consider Span and Gamel side-by-side:
| Player | PA | fWAR | rWAR | WARP | wRC+ | BB% | Pitches per PA |
| Denard Span (w/ SEA) | 328 | 0. |
