Those are two mammoth home runs. More, those are two mammoth home runs hit by the same guy — one Chad Pinder. Pinder is a 25-year-old infielder who’s topped out as Baseball America’s No. 7 Oakland prospect. In Pinder’s best professional season to date, he went deep 15 times. He’s gone deep four times over his last six big-league starts.

Pinder clearly has pretty good power. Keep that in the back of your mind. There are nearly 1,700 players with at least 50 batted balls in each of the last two seasons, including both the minors and the majors. Here are the 10 players with the biggest drops in ground-ball rate:

Whole bunch of minor leaguers. One Alex Avila out in front, about whom Dave just wrote. Avila has dropped his grounder rate by a stunning 30 percentage points, and that’s insane, but it’s also insane that Pinder is in ninth, having dropped his own grounder rate by 21 points. Pinder’s year-to-year track record:

2013: 41% grounders

41% grounders 2014: 46%

46% 2015: 48%

48% 2016: 42%

42% 2017: 21%

One of those stands out from the others, and although it’s still early, and although things can still shift, what’s remarkable is remarkable. Suddenly, Pinder looks like he’s become an extreme fly-ball hitter. There’s power there to back it up. You know how Yonder Alonso has dramatically changed his own batting profile? His grounder rate is down by 19 points. Pinder has slightly bested that.

And oh, hey, Statcast. Out of everyone in the majors with at least 30 batted balls this season, Pinder ranks second — second! — in average exit velocity. He ranks fifth in average air-ball exit velocity. He ranks seventh in rate of batted balls hit at least 95 miles per hour. Pinder has hit nine so-called “Barrels”, which ties him with, say, Carlos Correa and Anthony Rizzo, and Pinder hasn’t played very much. He’s basically insisting that he gets noticed.

So, consider him noticed. How far this goes, I can’t tell you. Dramatic early-season shifts don’t always reflect legitimate changes in true talent. Yet Pinder is off to a promising start, and just to the eye, his swing is quite pleasing. The A’s could have something here. The A’s could have something terrific.
