Spencer Horwitz Is Heating Up — And WaiverScout Saw It Coming
Spencer Horwitz just posted a .519 wOBA over his last 17 plate appearances while cutting his strikeout rate nearly in half. At 2% rostered, almost nobody is paying attention. That's exactly why you should be.
The Signal Is Strengthening
WaiverScout first flagged Horwitz as a watch back on April 13, then downgraded him to deprioritize on April 14 when the data wasn't there yet. The algorithm was right to wait. Now the numbers have caught up, and the signal is clear: Horwitz has been on an unmistakable upward trajectory across every meaningful rolling window.
Look at the wOBA progression: .352 over 30 days, .420 over 14 days, .519 over the last 7 days. That's not noise — that's acceleration. His batting average follows the same curve: .271 to .310 to .429. The plate discipline numbers tell you this isn't just BABIP luck. His strikeout rate has plummeted from 18.1% over 30 days to 11.8% in the last week, while his walk rate has climbed from 15.3% to 17.6%. He's making better decisions at the plate and making harder contact.
The Quality of Contact Is Real
This is where it gets interesting. Horwitz's exit velocity has jumped from 87.3 mph over 30 days to 94.5 mph in the last 7 days — a massive 7.2 mph improvement. His hard-hit rate has surged from 33.8% to 45.8% in that same window. Over 35 plate appearances and 5 games, this isn't a single-game mirage. The data is clear: Horwitz is squaring baseballs up with authority he wasn't showing earlier in the season.
His recent game log backs this up. A 3-for-3 performance on April 17 with a walk. A home run on April 19. A 2-for-4 line on April 22. He's been consistently putting together quality at-bats, not just riding one explosive game.
The Fantasy Landscape
The Sporting News noted before the season that Horwitz could be a major steal for fantasy owners. That early-season buzz hasn't translated to roster percentage — he's sitting at just 2% with zero ownership velocity. The industry is sleeping on this.
At first base, you're likely looking at the Freddie Freeman tier or bust in most leagues. But Horwitz doesn't need to be Freeman to have value. In deeper leagues or as a streaming option, a first baseman walking at a 17.6% clip and slugging with real authority has utility — especially one who's available in virtually every league on the planet.
Why Watch and Not Add?
The 30-day numbers still anchor the overall picture, and .271/.352 over 72 plate appearances isn't screaming must-roster. The hard-hit rate at the 14-day and 30-day windows (34.3% and 33.8%, respectively) suggests the 45.8% we're seeing now may regress. We need to see this elevated exit velocity and contact quality sustain for another week before the signal upgrades to a clear add.
The improving plate discipline is the most encouraging piece. A hitter who's walking in 15-17% of his plate appearances while simultaneously reducing strikeouts is making a real adjustment, not just getting lucky. If the hard-hit numbers stabilize above 40%, this becomes an add in all formats.
Verdict: Watch
Spencer Horwitz belongs on your watch list immediately. The wOBA trend is surging, the plate discipline is elite, and the exit velocity spike suggests something mechanical has clicked. At 2% rostered, you have time — but not much. If this keeps up through his next 5-7 games, the window to add him for free will close. WaiverScout identified this signal early, and the data has only strengthened. Keep him on your radar and be ready to move.
