Landen Roupp Is Doing Exactly What We Told You He Would

Landen Roupp just posted a 0.82 ERA with a 10.64 K/9 over his last 11 innings, and if you've been following WaiverScout, none of this should surprise you. We first flagged Roupp as a watch back on April 5 when his roster percentage sat at a laughable 7.1%. By April 10, we escalated him to Add Now at 19% ownership. He's now at 48% and surging — up 28 percentage points in the last week alone. The window to act for free is closing fast.

The Numbers Are Accelerating

What makes Roupp's breakout compelling is that the rolling windows tell a story of a pitcher getting better, not just riding a hot streak:

  • 7-day: 0.82 ERA | 10.64 K/9 | 2.65 FIP | 11 IP
  • 14-day: 1.06 ERA | 9.00 K/9 | 2.69 FIP | 17 IP
  • 30-day: 2.45 ERA | 10.09 K/9 | 2.22 FIP | 33 IP

That 30-day FIP of 2.22 is elite-tier — the kind of number you see next to names like Paul Skenes, not mid-rotation waiver wire adds. His ERA has been converging downward toward that FIP, which early signs suggest is the real skill indicator here. The 7-day strikeout rate has spiked to 31.7%, up from an already-strong 27.8% over 30 days. That's not noise — that's a pitcher who could be refining his approach in real time.

The Strikeouts Are Real

A 31.7% strikeout rate over the last seven days demands attention. For context, his 30-day K/9 of 10.09 already placed him among the most effective arms on the wire. His most recent outing — 7 strikeouts against just 5 baserunners allowed — shows the kind of dominance that earns a pitcher permanent rotation trust in San Francisco. He's logging full starter workloads too, with 11 innings in the last week confirming his role is secure.

The FIP tells us this isn't smoke and mirrors. At 2.65 over the last seven days and 2.22 over 30, Roupp is generating outs through skill — strikeouts and limited damage — not defensive luck or sequencing fortune. That's the kind of foundation that holds up as sample size grows.

The Ownership Window Is Closing

At 48% rostered with a +28% weekly velocity, Roupp is going to be universally owned within days. FantasyPros and CBS Sports both have active pages tracking his fantasy value, which means the mainstream fantasy community is catching on. RotoWire is monitoring him as well. The signal has gone from underground to consensus — but in over half of leagues, he's still sitting there unclaimed.

We need to be transparent about the sample size here. We're working with 33 innings over 30 days, and this confidence level remains an early signal. The skills profile could be emerging as legitimate, but regression is always possible. That said, the data points we do have are remarkably consistent across every window, and the trend line is pointed in the right direction.

Verdict: Add Now

Landen Roupp is an Add Now. A 2.22 FIP over 33 innings, a strikeout rate north of 31%, and a locked-in rotation spot make him one of the most valuable arms available on the wire right now. He profiles as a legitimate contributor alongside established starters like Michael King rather than a streaming option. WaiverScout identified this signal at 7.1% ownership. If you waited, you still have a chance in most leagues — but that chance evaporates this week. Go get him.
