Carson Kelly catches bear

As half of the most productive tandem of the Grand Slam, Carson Kelly doesn’t have enough cricket appearances to win the batting title, but like Will Smith of the Dodgers, he’s so far very productive, especially in the scoring position. Unlike Smith, he has no long record of success. Not only has Kelly never been an All-Star team in part of his 10 major league seasons with five teams, he played only 100 games in a season and won 100 WRC+ or better. However, he is participating in the breakthrough sport of the NL Central-leading Bears due to changes in swing mechanisms over the past few seasons.

The 30-year-old Kelly hit .290/.412/.589, with nine home runs and 179 WRC+ making appearances in 131 sets. He has started 28 games in 56 games behind the plate, and Miguel Amaya made the injury last weekend due to tilting pressure, an injury that interrupted a promising start to the 26-year-old defender’s season. Although Kelly was homer after replacing Amaya after losing to the Reds on Saturday, he was limited to a late cameo for the next three days due to an unspecified illness before returning to the roster on Wednesday night. The Cubs did not recall the prospect of 21-year-old Moisés Ballesteros, who spent five games for the Cubs earlier this month, but their defense needed to be more refined, instead raising Reese McGuire from Iowa Triple A to replace Amaya on the roster. When Kelly fell ill, he started all three games, twice against the Reds in his season debut. All in all, the three of the Cub Catchers are excellent at offense:

The Cubs’ total catcher total is the highest home run total, percentage of slips and WRC+ on any team except the Mariners. Individually, the hit statistics of the three bears did not originate from large samples, and Kelly’s performance particularly appealed to the mind, Jazayerli’s backup catcher law: “[G]Inven has enough chances, and the backup catcher will have a season where he hit 0.300 with less than 200 bats. “I’m more free to explain the law about Kelly’s overall offense, but this is still a career player who signed 1.224/.307/.373 (85 WRC+) for two years in December last year.

Kelly was originally drafted by a high school in Portland, Oregon (Portland, Oregon), and as a third baseman, Kelly was once regarded as the heir to Yadier Molina. He switched from third base to catcher in 2014, and three years later, he beat the top 100 prospect roster (he ranked 81st in our game) thanks to a combination of “rock” defense and “limited but innocent offensive ability”, using the words of Eric Longenhagen. Kelly spent some time with the Cardinal in 2016-18, but the team never worked on Molina’s main substitute, partly because he didn’t hit (.154/.227/.188, 16 wrc+ in 131 PAs in those three seasons), partly because Molina’s durability and durability and long-lasting strength are not much more than one. In December 2018, the Cardinal traded Kelly to the Rattlers as part of the Paul Goldschmidt blockbuster, who worked as a regular catcher for Arizona for the next four seasons, hit 5.0 wars in two good seasons and two happy guys, and met .231/.318/.405 (95 wrc+) in two good seasons and wrote about the tough guys.

Kelly made a bad breakthrough in the form of a fractured ulnar during spring training in 2023, a result of the White Sox’s Gregory Santos. When he returned to the roster on June 12, Gabriel Moreno established his achievements in the Grand Slam and released Kelly after struggling on the plate in mid-August. He quickly caught the tiger planned for him. They encouraged him to adopt a knee crouch behind the plate and helped him overhaul the swing after picking up the $3.5 million option that winter, in the two sites of that season, a belief in a limply that produced 56 WRC+ (.206/.278/.287) in his two stops. Articles from April 11 Chicago Suntime Maddie Lee:

He focused on the speed of the bat and the more straight-forward fairway, believing that this would solve his problem with a low court and breaking the ball.

“Basically, try a lot of different things,” Kelly said. “We’re going to put our hands down; we’re going to put our hands higher. We’re going to change the angle of the bat at the starting point.”

…Kelly’s hand lowered a little. Kelly has faster, more efficient bat paths, and has more time to identify tones and make swing decisions.

Kelly’s offensive rebound, which last year he hit 108 WRC+ with the Tigers before being traded to the Rangers on July 28 for Liam Hicks and Tyler Owens; Detroit was 52-55 at that time, and it seemed like it would be sure to kick the strings out. Of course, they hyped up, snatching wildcard berths, while Kelly’s Rangers (only 51-55 in the trade) were below .500. Kelly dropped to 81 WRC+ for the rest of the time and ended the year with the 0.238/.313/.374 (99 WRC+) line and 1.8 WAR, which remains his best performance in the last two categories since 2021.

Since signing with the Cubs, Kelly has continued to refine his swings to hit more frequently than last year, when his 46.3% ground rate was the highest since his cardinal. He told sportsSahadev Sharma in late April. More:

“One of the big changes Kelly made was the weight distribution between his hind feet and forefoot. It used to be a 50-50 distribution. But now, the force plate data tells him that his hind feet are 70-30 heavier.”

Here is a visual comparison of Kelly’s 2023 and ’25 positions:

Like Sharma, I chose Dodger Stadium in order to best keep camera angles and background consistent (it wasn’t easy to do given Kelly’s unification and league changes). You can see the lowered hand and the degree of his squat is slightly lower. His Statcast hitting posture and swing path metrics are a bit noisy given his experiments and travels, but I think his last stretch with the Rattlers (from the end of the All-Star break to his 2024 release) captures these changes well compared to his all-2024 and ’25 averages:

Relative to the end of his Arizona position, Kelly has moved back nearly three inches (the depth of serving) in the box and stretched out about an inch from the plate (distance), while closing a few inches between his position and his feet; he went from 26.8 inches in Arizona around 20 inches last year, opening to 24.6 inches this year:

Additionally, Kelly increased the speed of some bats and increased the angles of his swing path (his swing arc) and attack (vertical angle of his bat’s optimal position), resulting in the pursuit of the loft after the pursuit. He is bringing contact to the front of the board (intercept). He didn’t show it in the table above, but it’s also relevant that he pulled the ball from two degrees to five degrees to more angles.

Nevertheless, Kelly’s contact quality has been greatly improved. His average exit speed increased by three miles compared to last year, increasing his average launch angle by 1.6 degrees (reflecting the speed of the ground ball, down 2.4 percentage points), doubled his barrel rate and nearly doubled his aerial speed:

Kelly’s average 3.1 mph exit rate growth is 11th among players with at least 300 PA last year and 100 this year, while his barrel rate has increased by 6.6%. He increased his expected slip percentage by nearly 140 points compared to last year and nearly doubled his tough 2023 season:

Kelly surpassed his expected numbers, but not much was particularly frequent. His excellent board discipline strengthened his progress: his pursuit rate dropped from 23.5% to 17.9% of the low and his swing strike rate dropped from 9.5% to 8.1%. Therefore, his career is at a maximum of 16.8% (about 7 points than his career), and only 13% of the time (about 7 points than his career). What really caught my attention was how he controlled the runner’s scoring position, which I discovered during my research on Smith earlier this week:

These are not typos. Kelly is more than four times the frequency as he hits the runner in the scoring position, which in this case helped him reach the highest WRC+ for any batsman at least 40 pa. Smith scored a different score than the base void (27.4% vs. 12.9%) compared to Smith, and Kelly refused to chase (17.4% vs. 21.5%) in this case. It turns out that even though he didn’t play like hard last year, Kelly’s runners in the scoring position were excellent (.328/.455/.639, 208 wrc+ in 77 PA), with a higher walking rate than strikeout rate (14.3% vs. 7.8%) and even nearly the same rebuild rate (17.5%) in this case (17.55%).

If you’re wondering if Kelly wants to maintain such a hot start, the answer is already “he doesn’t.” Because his current numbers are strong, his return is already in progress as he hits only .228/.313/.368 (96 wrc+) at 64 PA on May 64, while 67 PA in March and April and 4 in April, his return rate is .360/.507/.840 (258 WRC+). In the recent leap, he made 10.9% of his batting, despite a hard hit rate of only 30.4%, with an average exit speed of 87.6 mph. The real question is whether he can get back to last month’s job, although he does seem to be on the rise again:

Kelly took out four to six weeks of play, and Kelly’s numbers could get most of the game time, meaning he would be more exposed and experience more wear and tear while working hard, even the most productive catcher. Nevertheless, the success he has tasted recently has given him a point of reference for something that works, and although he has to adjust to a pitcher to illustrate this, he has shown the flexibility to do so.
