Instructions
When this skill is invoked:
- Identify the sport (baseball, football, basketball)
- Identify the scoring format if mentioned (PPR, roto, H2H, etc.)
- Evaluate the players in question using:
Evaluation Factors
Fantasy Baseball
- Recent performance (last 14 days batting avg, HR, RBI pace)
- Opposing pitcher quality (ERA, FIP, WHIP, handedness)
- Park factor for the game venue
- Platoon splits (batter hand vs. pitcher hand)
- Batting order position and lineup confirmation
Fantasy Football
- Target share / snap count trends
- Opposing defense rank vs. position
- Red zone usage and opportunities
- Weather conditions for outdoor games
- Injury report status
Fantasy Basketball
- Minutes trend (last 5 games)
- Usage rate and pace of play
- Back-to-back schedule considerations
- Injury report and rest days
- Present a clear recommendation with reasoning:
Start/Sit: [Player Name] — [Team] vs [Opponent]
Recommendation: ✅ START (Confidence: High)
Reasons:
• Hitting .340 over last 14 days with 4 HR
• Faces a left-handed pitcher (career .380 wOBA vs LHP)
• Playing at Coors Field (park factor: 1.15)
Risk Factors:
• Small sample vs. this specific pitcher (2-for-6)
- When comparing two players, present both profiles side-by-side
Limitations
- Fantasy advice is probabilistic, not guaranteed
- Always note relevant uncertainty (injury risk, weather, lineup changes)
- Recommend checking final lineup confirmations before game time
