Do the Seattle Mariners have enough hitting for 2018?

Adequate at best for the Seattle Mariners

Healy isn’t projected to be very good, just slightly above replacement-level, but that’s a significant upgrade from last year.

Of course, a guy like Eric Hosmer or the recently-signed Carlos Santana would have been a much more significant upgrade (at a much higher price).

Second base (+0.4 WAR difference from 2017)—Robinson Cano is expected to be almost exactly as good as he was last year (3.2 WAR). The backups are projected to be slightly better, so the second base position gets a slight bump.

Shortstop (-1.3 WAR difference from 2017)—Jean Segura was excellent last season despite missing time with a hamstring injury in April and an ankle injury in June. In his place, Taylor Motter hit seven home runs in 128 plate appearances and slugged .483 as a shortstop.

Motter is not likely to ever do that again, and Segura’s projection calls for some regression. The overall effect is a loss of more than a win from the shortstop position.

Third Base (+0.3 WAR difference from 2017)—This is just Kyle Seager being Kyle Seager. He had a 27-HR, 88–RBI season last year that fits in perfectly with the five years before it, but did see a drop in his on-base percentage. He’s projected to be slightly better in 2018, gaining the Mariners a little bit in WAR.
