Hard, Into the Ground

In the second week of May, in Las Vegas, Henry Bolte went 5-for-5 with two home runs, two doubles and a triple.

It was part of a stretch in which he reached base by hit in twelve consecutive plate appearances. He was the Pacific Coast League's player of the week. He had twelve home runs and seventeen stolen bases in thirty-seven games and he was batting .348.

"He kind of forced the hand," his manager, Mark Kotsay, told MLB.com. "We're going to get him playing time for sure."

The Athletics called him up on May 12. He debuted the next day against St. Louis and singled twice.

"Growing up an A's fan, every kid dreams of debuting for their home team," he said.

Since then, most of what he has hit has gone into the ground.

He was born in San Francisco and grew up in Palo Alto, and as a senior at Palo Alto High he hit thirteen home runs, more than any other high school player in California. The A's took him in the second round in 2022, the fifty-sixth pick, and gave him two million dollars.

Then Stockton, and Lansing, and Midland. He stole thirty-two bases in 2023 and forty-six in 2024. He hit fourteen home runs, then fifteen. He struck out in about a third of his trips to the plate.

MLB Pipeline grades him hit 45, power 55, run 65, arm 50, field 50 — and in the prose underneath the numbers calls it "70-grade raw power from a whip-quick bat," while noting that "his hit tool and approach have invited questions about whether he'll make enough contact."

Everything about him is loud except the part where the bat meets the ball.

Last spring Kotsay was asked about him and said this:

"There's a lot of us in that coaches' room that think this kid has the ability to be a real star."

The first two months went well enough that nobody had to ask the question.

He took over center field. He hit leadoff. He stole ten bases in thirteen tries. On June 9 he hit his first major-league home run, off Milwaukee's Robert Gasser, a two-run shot to right-center. Late in June his average was .317.

On June 27, Jason Burke wrote a piece for Yahoo Sports pointing out that the .317 wasn't what it looked like.

Bolte's expected batting average that day — what his contact actually deserved, given how hard and at what angle he hit it — was .241. Among qualified major-league hitters at that point in the season, Burke found, nobody hit the ball on the ground more often: 64.7 percent of the time, one of only four men above sixty.

And his average launch angle was negative.

A ball that leaves the bat at zero degrees is travelling parallel to the ground. Bolte's, on average, was leaving at minus six-tenths of a degree. Not low. Down.

He was beating them out. He runs, by Statcast's measure, at 30.5 feet per second — the fastest average sprint speed of any player in the major leagues, and the fastest anyone has recorded since the metric began in 2015. He hit the ball hard enough that the grounders he didn't beat out went through the infield instead. For two months it worked.

Burke quoted Kotsay on why nobody was worried.

"The one thing that doesn't slump is speed."

In July, Henry Bolte hit .152.

His on-base percentage for the month was .204. He did not steal a base. On the 18th he was out of the lineup against Washington. On the 22nd, after going 1-for-9 across three starts, he was out of it again for the series finale against Arizona, and Lawrence Butler, whose job Bolte was supposed to be taking, played center field in his place.

He started on the 25th, in center, and the A's lost 2-0.

The season line is .247/.326/.328 across sixty-two games. Three home runs. His expected average is now .225 — which is to say the contact caught up with him. Kotsay was right about the speed. It didn't slump. It was doing as much for him in July as it did in June. It was never enough on its own.

Our own engine ranks Triple-A hitters by the quality of their contact — how hard the ball comes off the bat when they hit it. Bolte sits third on the twenty-name board it publishes, and the figure behind that rank has not moved a hundredth of a mile an hour in six days.

That last part sounds like stability and isn't. He hasn't taken a Triple-A at-bat since May 12. The number isn't holding steady; it's finished. What the board is reading is a thirty-seven-game sample from April and early May, in a park two thousand feet up in the desert air, in the most hitter-friendly league in the minors — and Las Vegas is generous even by the standards of that league. The 1.076 OPS he posted there is a real thing he did and a Las Vegas thing at once, and it stopped being current the day he got on the plane.

What the rank does tell you is true and narrow: when this man hits a baseball, he hits it very hard. That was true in Las Vegas in April and it's true in the majors now. His average exit velocity is 90 miles an hour. He has hit one 113.6. Better than 46 percent of his contact qualifies as hard-hit.

The number measures how hard he hits it. It does not measure the angle it leaves at. And roughly three of every five balls he puts in play go into the ground, and he has three home runs, because a ball struck at 113 miles an hour into the dirt in front of home plate is a ball struck at 113 miles an hour into the dirt in front of home plate.

He swings and misses, too. A third of the time he offers, he comes up empty, against a league average of a quarter. That's the flaw the scouting reports named, and it's real. It isn't the one costing him the most.

The Athletics know all of this. Kotsay, asked on A's Cast about the missing power:

"The power will come. It's a matter of time. He's getting attacked with a lot of sinker right now. We're working on getting him into his legs to be able to elevate the ball a little bit more. But we don't want to change much about Henry."

Which is the whole problem stated kindly. They want the ball in the air, they don't want to touch the swing that isn't putting it there, the pitchers have worked out what he does with a sinker, and he's twenty-two years old and finding all of it out in front of everybody.

He turns twenty-three on August 4.

The A's are playing their home games in Sacramento, in a minor-league park, while they wait to move to Las Vegas — so he was promoted out of the city the franchise is going to and into a borrowed one it's leaving from. Their outfield is thin. The runway is there if he can use it.

There's a version of this where the ball starts going in the air, and the seventy-grade power that has been going into the infield dirt starts clearing fences instead, and the fastest legs in baseball are still under it, and the coaches' room turns out to have been right about the star.

There's also a version where the swing is the swing.

Which one it is gets decided one lineup card at a time, four or five nights a week, in a borrowed ballpark in Sacramento.

He wasn't on the card Wednesday. He was on it Saturday.
