Jakob Marsee’s season at the plate has already taken a hit, but the more complicated conversation is out in center field, where the numbers refuse to agree on what kind of defender he really is.
On one side, Defensive Runs Saved paints a rough picture. Marsee sits at minus-11, a number that puts him near the bottom of the league.
Statcast, though, tells a far friendlier story. It has him at six Outs Above Average, which lands him in the 92nd percentile across baseball.
That split starts with what each stat values. OAA is built around whether an outfielder gets to and converts balls in play, factoring in distance, time and direction. Marsee checks those boxes because he can move, react and cover ground.
The Statcast breakdown backs that up. His reaction is 1.6 feet above average, and his burst adds 0.4 feet.
The problem is the route work, which comes in 1.2 feet below average. Even with that flaw, his overall jump still sits 0.8 feet above average.
So Marsee can get away with some inefficient routes because the athletic tools show up fast enough to rescue him. That goes a long way toward explaining why OAA likes him so much.
DRS looks at the full defensive package and is much less forgiving. Marsee has been charged about four runs below average in the metric’s range component, and his arm has cost Miami another six runs. Add in one run below average from good plays and defensive misplays, and the total lands at minus-11.
That doesn’t mean the stat should be treated as the final word on his defense, especially when it comes to range. Statcast says he reacts to balls well above average, and that’s something you can see on the field too.
Pete Crow-Armstrong is a strong example of why these individual pieces need context. Even with his elite range, DRS has him at minus-2 runs in good plays and defensive misplays.
Marsee is not Crow-Armstrong, and nobody is pretending he is. But the larger point holds: a center fielder can cover plenty of ground and still lose value through mistakes or other parts of his game.
The cleanest read on Marsee is probably somewhere in the middle. He does not look like the standout defender his OAA number suggests, but he is also not the disaster his DRS total makes him out to be.
He’s an athletic center fielder with quick reactions, shaky routes and an arm that can get him in trouble. The metrics disagree, but together with the eye test, they give a fuller picture.

Eury Prez Just Gave Marlins Fans A Painful Wild Card Reminder
Eury Prez had been giving the Marlins the kind of lift they badly needed in his recent starts, but Friday brought a harsh reminder of how thin the margins still are in Miamis rotation. Against the Nationals, the young right-hander ran into trouble in the third inning and never really settled in, as Washington kept building on the opening and Miami finished with a 9-2 loss.
Prezs command looked shaky as the inning unraveled, and the outing came after a stretch in which he had been much more effective. On the other side, Nationals rookie Jackson Kent picked up his first career win, while Washington added on later to turn the game into a comfortable one. For the Marlins, it was the sort of night that makes every missed chance feel heavier, especially with the playoff race always lurking in the background. [Read more 🡒]
Eury Prezs Rare Stumble Raises A Bigger Marlins Concern
Eury Prezs recent run of steadier pitching had been one of the more encouraging signs for the Marlins as they tried to keep their season moving in the right direction. In the opening game of their road series against the Nationals, though, the young right-hander had a rough one, and Miami could not recover in a 9-2 loss that set an early tone for the trip.
Prez was tagged for five runs in three innings, with the command issues and the long ball combining to make this feel more like a detour than a trend. He has generally looked more like himself since coming back from the injured list, which is why the bigger question for Miami is whether this was just an off night or the start of another stretch where the margin for error gets too thin.

Marlins Have Found A Playoff Weapon Few Teams Can Match
Speed has become more than a theme in Miami this season, it has turned into a defining part of the Marlins identity. Under manager Clayton McCullough and first-base coach Craig Driver, the club has made base stealing a deliberate strategic focus, with preparation and intent built into how they want to pressure defenses and create runs during the regular season.
That approach has now given Miami a weapon few clubs can match, with Otto Lopez, Esteury Ruiz, Xavier Edwards and Jakob Marsee all giving the lineup another layer of threat once they reach base. For a team still trying to stay in the postseason picture, that kind of depth on the bases can matter just as much as a big swing, and it leaves open an intriguing question about how far that speed can carry them if the race tightens.
