The macro picture is ugly for old hitters
Per FanGraphs data reported by the Associated Press, MLB hitters aged 35 and older combined for just 5.6 WAR through roughly the first third of this season. For context, that same group produced 71.3 WAR in 2003. The aging curve has not just steepened. It has fallen off a cliff, and the league's velocity explains why: the average fastball in 2026 sits north of 94 mph, with 18 qualified pitchers averaging at least 96.
The lesson for dynasty managers is that the decline phase you remember from older player pools no longer exists. There is no gentle three year glide path anymore. There is a good season, a warning sign, and a collapse, usually in that order and usually faster than the market prices in. Here are three current cases, each representing a different version of the problem.
The mirage: Paul Goldschmidt
Goldschmidt is having a feel good rebound at 38 with the Yankees, and if you roster him in a dynasty league, this paragraph is the best trade window you will get.
The surface is spectacular. After hitting .226/.277/.333 over the final four months of 2025, per MLB.com , Goldschmidt has raised his OPS nearly 200 points and hit eight home runs since Aaron Judge's rib injury in late May, more than all but three hitters in baseball over that span. The story writes itself: veteran finds fountain of youth in the Bronx.
The problem is that MLB.com 's own deep dive into the rebound found the opposite of what sustainable rebounds look like. Goldschmidt is swinging slower, hitting the ball more softly, and chasing and whiffing more than last year. And the June numbers are the tell: per Pitcher List, his June wOBA was .441 against a .293 expected wOBA, ranking 6th and 131st respectively among 172 qualified hitters. That is one of the largest luck gaps in the sport, and by early July, Pitcher List noted the correction had already begun.
