Tier 1 — Must Start (any league size)

Three bona fide aces (99%+ ownership on two of them) all line up for two starts this week, which is the macro story — you're not really streaming in Tier 1, you're just confirming that yes, you start them twice. The middle of the board is where the week breaks open: Davis Martin at 56% and Aaron Nola at 64% are the most interesting decisions, and there's a genuine 15-team-only flier in Shane Baz. The second starts across the board carry low confidence tags, so weigh the Sunday/Saturday games as bonus rather than baseline.

Tarik Skubal (DET, 99.0% owned)

• Starts: 2026-05-04 and 2026-05-10
• Why: Reigning Cy Young-tier arm, elite K9 with sub-1.00 WHIP profile, and 99% ownership tells you the market sees zero matchup-dependence here.
• League notes: Auto-start in all formats — 12T, 15T, points, 5x5.

Jacob deGrom (TEX, 99.0% owned)

• Starts: 2026-05-05 and 2026-05-10
• Why: When healthy, the best ERA/WHIP/K9 combo on the planet; 99% ownership reflects that the injury risk is already priced in and you start him every time he toes the rubber.
• League notes: Auto-start in all formats.

Cam Schlittler (NYY, 97.0% owned)

• Starts: 2026-05-04 (high conf) and 2026-05-09
• Why: 97% owned with a high-confidence first start means the league has caught up to the swing-and-miss profile; Yankees offensive support adds W equity in 5x5.
• League notes: Auto-start in all formats.

Tier 2 — Confident Streamers (12-team and deeper)

Davis Martin (CWS, 56.0% owned)

• Starts: 2026-05-04 (high conf) and 2026-05-10
• Why: High-confidence first start, sub-4 ERA trajectory, and at 56% owned he's the best add/start combo on the board for ratios + a punt-friendly K rate.
• League notes: Start in 12T and deeper; in points leagues check the second opponent before locking.

Aaron Nola (PHI, 64.0% owned)

• Starts: 2026-05-04 (high conf) and 2026-05-09
• Why: Two starts, high-confidence opener, and a K9 north of 9 even in down years; 64% ownership means he's still freely available in shallow leagues.
• League notes: 12T must-start, 15T lock, strong points-league play given innings volume.

Gavin Williams (CLE, 94.0% owned)

• Starts: 2026-05-05 (high conf) and 2026-05-10
• Why: 94% owned for a reason — mid-3s ERA upside with a K9 flirting with double digits; high-confidence first start makes this a clean two-start week.
• League notes: Start in all 12T+ formats.

Sandy Alcantara (MIA, 94.0% owned)

• Starts: 2026-05-05 (high conf) and 2026-05-10
• Why: Volume monster — innings + WHIP suppression are the carry tools, and a high-confidence opener locks in the floor even if K9 lags the elite tier.
• League notes: Auto-start in points and 15T; 12T 5x5 managers should still run him out twice.

Tier 3 — High-Variance Sub-30% Plays (15-team only)

Nick Martinez (TB, 32.0% owned)

• Starts: 2026-05-04 and 2026-05-09
• Why: Tropicana-adjacent run suppression and a WHIP that plays up in deeper formats — the one compelling reason is ratio stability across two starts.
• League notes: 15T only; skip in 12T 5x5.

Reynaldo López (ATL, 18.0% owned)

• Starts: 2026-05-04 and 2026-05-10
• Why: When the fastball is playing, the K upside is genuinely top-30; 18% ownership means you're buying low on a former sub-2 ERA arm.
• League notes: 15T flier, AL/NL-only must-add.

Shane Baz (BAL, ?% owned)

• Starts: 2026-05-04 (high conf) and 2026-05-09
• Why: High-confidence first start plus stuff metrics that have always graded ahead of the surface ERA — the lone reason here is upside.
• League notes: 15T speculative add; monitor before deploying in 12T.

Avoid This Week

Eric Lauer (TOR, 6.0% owned)

• Two starts at 6% owned with low second-start confidence and a fly-ball profile that doesn't survive the AL East — leave him on waivers even in 15T.

A.J. Puk (ARI, 1.0% owned)

• Chase Field run environment plus a reliever-converted role at 1% ownership means you're chasing volume that may not materialize; pass in all formats.
