Carter Jensen Rookie Season: Two Records in Two Weeks
He hit .187 in July. Then he set a record no catcher had ever held, and pulled within three of a Kansas City mark from 1994.
Catchers do not bat leadoff. No rule says so. Baseball simply arranged itself that way long ago, and the reason is the squat. A catcher is down and up for three hours a night, and foul tips find the mask, the forearm, the thigh. So managers protect him. He hits seventh, or eighth, or ninth, where tired legs cost the lineup the least.
Kansas City keeps writing Carter Jensen’s name at the top instead. Over eight days at the end of August and the start of September, that decision produced two record books’ worth of evidence.
The rookie was already there
Jensen is 23. He grew up in Kansas City and caught at Park Hill High School, about 22 miles from Kauffman Stadium, and in 2021 the Royals drafted him in the third round, 78th overall.
He debuted on September 2nd of last year and hit .300 across twenty games as a September call-up. He made the Opening Day roster this spring and has been Kansas City’s primary catcher since. This season he has caught 88 games and started 80 of them.
His season line does not glitter. Through the end of August he was batting .223. He is a rookie learning the hardest job in the sport at the highest level it is played, and the average says so plainly.
July took the bat and left the job
July was the worst of it. Jensen hit .187 that month and struck out in nearly four of every ten trips to the plate.
He kept catching. That is the half of the month no box score shows. A slump does not excuse a catcher from the squat, so he worked through the hottest weeks of a Kansas City summer with his own swing gone missing. He still blocked. He still ran a pitching staff.
The evidence is in a number almost nobody quotes. In mid-August, Jensen ranked tenth in the majors in shadow-strike percentage at 48.9 percent — the share of borderline pitches he turns into called strikes, the ones an umpire could call either way. He was stealing strikes for his pitchers on the same legs that carried him to the plate first every night, in the month his own bat gave him nothing.
August 27: the record
At Rogers Centre in Toronto, Jensen opened the game against Blue Jays starter Spencer Arrighetti and drove the first pitch he liked 421 feet.
It was his fifth leadoff home run of the season. No catcher in the history of the sport has hit more in a single year. The record had belonged to Paul Lo Duca, who hit four of them in 2001 — two years before Jensen was born.
A leadoff at-bat arrives before anything else does. The crowd is still finding seats. Nothing has happened yet, to the game or to the catcher’s legs. It is the one trip to the plate a catcher takes before his job has taken anything from him. Jensen has turned it into a record five times this summer, and then spent the next three hours doing the work that usually keeps a catcher hitting ninth.
Kansas City won that night 13-2. Jensen finished 1-for-2 with three walks and two runs scored.
September 2 and 3: the chase
Wednesday was one year to the day since his major-league debut, in the same ballpark, in his hometown. He marked it with two home runs — one to lead off the Royals’ half of the first at 414 feet, one in the fourth. Both solo. Miami won that game 9-6 anyway.
Thursday he came back and nearly hit for the cycle.
| Date | What he did | RBI | Runs | Season HR |
|---|---|---|---|---|
| Wed, Sept 2 | 2 HR, both solo | 2 | 2 | 21 |
| Thu, Sept 3 | HR, 3B, 2B (3-for-4) | 3 | 3 | 22 |
The 440-foot drive to right-center on Thursday was his 22nd of the year, and it left him a single shy of the cycle. It is also the second-most home runs any Royals rookie has ever hit, tying Carlos Beltrán in 1999 and Bo Jackson in 1987. Only Bob Hamelin has more — 24, in 1994. Jensen needs three to pass him, with the last few weeks of the season left to find them.
“Super fun to see him do what he’s been doing the past couple of days,” said Jac Caglianone, the Royals outfielder who was named the American League’s Player of the Month for August. “I feel like every September, he’s just built for it.”
What the eight days actually prove
None of it happens if Jensen is not still in the lineup, and a rookie catcher hitting .187 in July is not guaranteed to be. He stayed there because the rest of his game never went cold.
That is the whole pattern, and it is worth carrying if you are the catcher grinding through a bad month. Your bat will leave you at some point this season. It leaves everybody. But the innings you catch while you wait are the ones that keep your name on the card. And the card is where every good September starts.
Try this at your next practice
- The two-column notebook. Draw a line down a page. Left column: your at-bats. Right column: your innings — blocks made, runners held, pitches called that worked. On a cold week, work the right column.
- Steal one strike a game. Pick a single borderline pitch each inning and receive it quietly, glove finishing inside the zone. Ask your coach afterward how many you got. That is the skill behind Jensen’s 48.9 percent.
- Ask why you hit where you hit. Then go earn a different answer. Kansas City did not put its catcher at the top of the order out of kindness. Sweat the gear and never fear.
