Landen Roupp Is Flashing His Best Stuff Again — Add Now

Landen Roupp's strikeout rate just jumped to 28.0% over the last seven days, up from 23.3% over the trailing 30 days, and the results are following the swing-and-miss spike. His 7-day ERA sits at 3.00 with a 10.5 K/9, and his 3.43 FIP confirms this isn't smoke and mirrors. If he's available in your league, the window to add him is closing.

The Rolling Window Story

The 30-day numbers look ugly at first glance — a 6.65 ERA across 20.3 innings. But that surface-level stat is masking a pitcher whose underlying skills have been far better than his results. His 30-day FIP of 3.94 tells you he was getting unlucky or victimized by sequencing. Now zoom in: the 14-day window shows the ERA dropping to 3.87 with a 3.71 FIP over 16.3 innings. And in the most recent 7-day stretch? A 3.00 ERA, 3.43 FIP, and that 28.0% strikeout rate over 6.0 innings of work.

The trend is unmistakable. The ERA is converging toward where the FIP has been pointing all along, and the strikeout rate is accelerating in the right direction. His most recent outing — 7 strikeouts in that start — was his best punchout performance in the five-game sample.

WaiverScout Called This Early

We first flagged Roupp as a Watch back on April 5 when he was rostered in just 7.1% of leagues. By April 10, we upgraded him to Add Now at 19% ownership. Managers who listened got him for free. When his surface stats ballooned, we responsibly moved him to Deprioritize on June 2 at 58% ownership — and his roster rate has since cooled to 46%. That dip created exactly the re-entry point we're acting on now. The skills never left; the results are catching up.

The Broader Fantasy Conversation

We're not alone in recognizing what Roupp is doing. FanGraphs profiled his effectiveness in late April, noting it wasn't immediately obvious why he was succeeding but that the results demanded attention. Yahoo Sports went further, arguing he was being "robbed" of broader fantasy recognition. The analytical community is catching on, but at 46% rostered, the market hasn't fully priced him in yet.

Ownership Window

Here's the critical detail: Roupp's ownership velocity is actually cooling off despite his improving performance. He's shed roughly 7% in roster rate recently, likely a reaction to that inflated 30-day ERA. This is a textbook buy-low window created by managers chasing results instead of reading skills. A 28.0% K-rate pitcher with a 3.43 FIP who is available in more than half of leagues is a market inefficiency, full stop.

We should note the confidence calibration here — early signs suggest this strikeout surge could be a sustainable shift, but the sample remains small. Worth monitoring how the next couple of starts unfold. That said, the FIP has been strong across all rolling windows, and the strikeout trend is moving in one direction.

Verdict: Add Now

Landen Roupp is an Add Now. The strikeout rate is rising, the FIP has been elite-adjacent for weeks, and the ERA is finally falling in line. He's occupying a rotation spot and throwing meaningful innings for San Francisco. If you're in a league where pitchers like Jacob deGrom or Roki Sasaki are long gone, Roupp is the kind of arm that can quietly anchor your staff. At 46% rostered and trending down, he won't be this available for long once the ERA fully corrects. Move now.
