Mariners Lineup Struggles: The Bottom Line
The bottom line is that the Mariners' best five hitters are striking out too much, not walking enough, can’t hit breaking balls, and are hitting into a lot of hard-ground ball outs. Overall, Julio and Cal are probably the least concerning based on the underlying numbers, while Polanco is the guy causing the most doubt, due to his long-term trends in K% and exit velocity.
The “spin-it-to-win-it” mantra has so far paid off for opposing pitchers against the M’s, and my guess is that it will continue to pay off until the Mariners learn how to lay off breaking balls and wait for a better pitch. Yes, it is still early, and yes, many of these trends will get better as the season goes on. But 1/10th in the season, the Mariners presumed top-5 hitters have failed to carry the weight, and the result has been the mediocre 6-10 record to start the year.
