Luis Arraez’s Launch Angle Revolution

On Tuesday night, as I watched Luis Arraez, sparkler in hand, chatting with Otto Lopez outside the National League dugout, I couldn’t help but reflect on how he ended up in Philadelphia. This is Arraez’s fourth All-Star selection, but it’s also his first in four years. Although we’re only 90 games into the season, his 3.7 WAR is already a career high. As you surely know, the biggest improvement in his game came with the glove. Michael Rosen put it simply enough back in May, with an article titled “Luis Arraez Is Good at Defense Now.” At the time, Arraez had put up 5 FRV over 30 games. In the ensuing 61 games, he’s accrued another 3 FRV. The pace has slowed down, but he’s still grading out as an excellent defender (though the other defensive metrics admittedly disagree).
Today, however, we’re interested in Arraez’s offensive improvement. Arraez won his first batting title in 2022, and he did more than just put up a high batting average. He also walked more than he struck out, earning a 130 wRC+. He followed it up with a 131 mark in 2023, though he did so in a slightly different fashion. Both his walks and his strikeouts dropped below 6%, but he ran a .362 BABIP, which led to a .354 batting average. Essentially, he leaned way, way into his status as a contact god, and the sky-high BABIP made it all work out beautifully.
But Arraez took things too far. In 2024 and 2025 combined, his walk and strikeout rates fell below 5%, and his .307 BABIP, while above the league average, wasn’t good enough to carry an offensive profile that features no walks and no power. He ran a 107 combined wRC+, and because he was putting up negative value in the other parts of the game, he ended up with just 2.0 WAR. That put his value squarely between an average player and a replacement-level one. Read the rest of this entry »
