However, upon a closer look at the stats, it's really not all that surprising.
Once the three-time All-Star was traded to the New York Yankees for Juan Then and cash considerations, the Mariners struggled to put together any string of wins and wound up cemented to the bottom of the American League West. This is, in part, due to the incompetency of his replacements.
Daniel Vogelbach slid over from DH to take his spot at first base, and he might as well be swinging with a water bottle lately rather than a baseball bat. It probably wouldn't make a difference.
The 26-year-old lefty batter is hitting a dreadful .173 in his last 30 games, along with 35 strikeouts.
Domingo Santana took over Encarnacion's space in the lineup, and has been as ineffective as Vogelbach recently. In his last 15 contests, Santana has maintained a minuscule .151 BA with 28 strikeouts and a .283 SLG.
It's safe to say that Seattle is drowning without the team's single-season grand slam leader.
