Cal Raleigh Has Helped Save the Mariners

Earlier today, Jake Mailhot broke down how two unheralded members of the Mariners’ relief corps have contributed to the team’s recent surge. Indeed, a lot has gone right for Seattle, but one area that has not been talked about as often is the catcher situation. In our preseason positional power rankings, the team ranked 16th at the position — not bad, but not great, either. So far, in real life, the Mariners are 14th. That’s not much of a difference, so you’d be inclined to think things have gone according to plan.
What Mariners fans would tell you is that Tom Murphy has been hurt, and Luis Torrens has been hurt and ineffective. Enter Cal Raleigh, who’s taken up the catching mantle all by himself, hitting .211/.288/.474 en route to a 117 wRC+ as of this writing. But it’s not a breakout many anticipated, nor did it come easy. In his first taste of the show last season, Raleigh hit for a mere 47 wRC+ in 148 plate appearances, then struggled to begin this season, ultimately getting sent down to Triple-A to recuperate. After rejoining the big league squad on May 7, however, Raleigh hasn’t looked back, providing big knocks for an aspiring squad ever since.
How did Raleigh pull it off? Like so many others before him, he simply started hitting the ball harder — shocking, I know. He has always possessed an uppercut swing, but mediocre exit velocities in his debut year meant his fly balls turned into outs, not extra-base hits. Now, he is supplementing those high launch angles with power. If we look at Barrels per plate appearances, which accounts for the fact that a per-batted ball basis tends to gloss over strikeout issues, Raleigh is one of the league’s most improved hitters. He’s highlighted below in yellow:

Among the 319 hitters in this plot, Raleigh ranks second in barrel per plate appearance gain, behind only Aaron Judge and tied with Rob Refsnyder and Christian Walker, represented by the points snuggled up to his right. Because barrel rates are reliable pretty quickly and stay consistent year-to-year, we can trust that major rises (and falls) aren’t just flukes. And evidently, Raleigh has made a couple tangible adjustments. During his seven-game stint in Tacoma, teammate Mitch Haniger told the young catcher he should hunt for the fastball, as that was the pitch he could handle. Given that only the best of the best can handle several ranges of velocity and movement, it seems like solid advice; not everyone can be Freddie Freeman. Read the rest of this entry »
