Do me favor. Don’t think about buying and selling Mookie Betts. Who would try this, anyway? As an alternative, think about Mookie Betts buying and selling Mookie Betts. That’s to say, think about Mookie Betts deciding to commerce the present model of himself for a youthful model of himself. Most of us would make that commerce in a second – my youthful self had a lot hair and was already studying at a fifth-grade stage! – however why would Mookie Betts make that commerce? Coming into 2024, he had simply put up a seven-win season whereas working a 166 wRC+, the second-best batting line of what ought to find yourself as a Corridor of Fame profession. That’s the best self, proper there. No trades crucial.
From afar, Betts’s 2024 season was of a bit with those that preceded it. He put up his eighth-career 4-WAR season and ran a 141 wRC+, virtually precisely consistent with his profession mark. However take a look at this:
Go forward and ignore the quick 2020 season, when Betts posted a low pull price. All of the numbers go up towards the second half of the graph earlier than dipping again down in 2024. In a few main methods, Betts regarded lots much less like what we’ve seen on this decade, and much more like what we noticed again within the first few seasons of his profession. He went again to hanging out much less, pulling the ball much less, and hitting the ball considerably softer. In case that graph isn’t clear to you, let me present you a similar numbers, this time break up up into three chunks: 2014 via 2017, 2018 via 2023, after which simply the 2024 season.
See the chunks? If these three metrics — Betts’ strikeout price, hard-hit price, and pull price — are ringing some bells, it’s most likely as a result of I wrote about them again in Could. On the time, I seen that pitchers have been doing their best possible to pitch Betts away, away, away. Effectively, that development continued all through the season, and it definitely appears doable that it explains quite a lot of these numbers. Persevering with with our theme, let’s take this in chunks. We’ll speak concerning the strikeout price first as a result of it’s the least dramatic.
Betts has by no means been something however wonderful at avoiding strikeouts. Nevertheless, he had an 11% strikeout price in 2024, and even by his personal ridiculous requirements, that was one thing. It was tied for the very best mark of his profession, it represented a virtually 30% drop-off from his 2023 price, and it put him within the 98th percentile of all main league hitters. The factor is, his plate self-discipline didn’t change all that dramatically. He noticed fewer pitches within the zone, which is an efficient method to keep away from strikeouts, however he additionally had one of many larger chase charges of his profession. The massive distinction was that he swung extra usually on the primary pitch and he recorded one of many highest contact charges of his profession. That’s a bit odd, as a result of chasing extra usually results in whiffing extra. Nevertheless, seeing extra outdoors pitches may result in extra contact, as the best contact level for an out of doors pitch is additional behind house plate, which provides the batter extra time to react. As I discussed, all of those numbers have been inside Betts’ profession norms, however between the aggression, particularly on the primary pitch, and the upper chase price, it appears secure to say that Betts was seeking to put the ball in play a bit extra usually.
On the similar time, Betts’ contact high quality took an infinite dip. His hard-hit price fell from 48.5% in 2023 all the best way to 39.5%. That also left him pretty near the league common, nevertheless it was one of many greatest drops in baseball, and the underlying numbers are even uglier. Betts’ ninetieth percentile exit velocity and his greatest pace (which throws out the weakest 50% of batted balls after which takes the typical of the remaining 50%) represented profession lows. The ninetieth percentile mark put him within the twenty seventh percentile. This isn’t the course during which you need to be trending.
As I famous again in Could, Betts adjusted to the skin pitches by establishing nearer to the plate. That may make it tough to hit the within pitch with authority, as a result of you’ve got much less time to activate it, however Betts’ contact high quality was down throughout the board. Right here’s his hard-hit price on pitches within the zone:
The inside third positively noticed the most important drop-off, however his hard-hit price was down on pitches out over the plate too. That brings us to our third and last chunk. Betts ran a 34.3% pull price, the bottom of his profession and not less than 10 share factors decrease than his price in every of the three earlier seasons. Listed below are spray warmth maps for 2023 and 2024. All the pieces’s shifting away from left subject and towards proper subject. It’s additionally shifting away from deep fly balls.
Betts has by no means been the strongest participant within the league, however he’s all the time hit the ball arduous, and he remodeled himself into one of many recreation’s true masters at turning on the within pitch and ripping it down the road or over the fence. In 2024, nonetheless, he traded that tremendous energy for the power to spray line drives to all fields. It definitely looks like this was a response to the best way he was being pitched. In spite of everything, it’s fairly arduous to yank a pitch on the skin nook down the left subject line. And if you happen to’re not seeing pitches you can yank to the pull facet, then it not is smart to construct your entire strategy round that objective.
I don’t need to overreact to a single season, not to mention one during which Betts produced his typical improbable offensive numbers — particularly contemplating that Betts missed practically two months with a fractured hand. That is a type of occasions after I actually want we had bat monitoring knowledge stretching again over the past a number of years. Betts had a median bat pace of 69.1 mph in 2024, which put him in simply the 14th percentile, and I want there have been a method to know whether or not that was an enormous drop-off from earlier seasons. He turned 32 final yr, and simply Tuesday, Tom Tango revealed an ageing curve that makes it seem like there’s a dramatic bat pace drop-off beginning at 32. Should you take a look at Betts’ spray charts and his contact charges, you get the sense that he simply reworked his strategy with the intention to profit from the pitches he was seeing. Nevertheless, the exit velocity numbers are such an excessive departure from his earlier seasons. To some extent, they’re most likely a symptom of that bigger adjustment, however Betts’ bat may be slower than it was.
