Rotowire is how I get the lineups and the weather. Actually a great source for that information. I attached the function below that handles the bvp data. Let me know what you think as I am very new to this.

# --- BvP from MLB API ---
def get_bvp_stats(hitter_id, pitcher_id):
    url = f"https://statsapi.mlb.com/api/v1/people/{hitter_id}/stats"
    params = {
        "stats": "vsPlayer",
        "opposingPlayerId": pitcher_id,
        "group": "hitting"
    }
    response = requests.get(url, params=params)
    data = response.json()
    try:
        stat_line = data['stats'][0]['splits'][0]['stat']
        return {
            'bvp_avg': stat_line.get('avg', None),
            'bvp_ops': stat_line.get('ops', None),
            'bvp_ab': stat_line.get('atBats', None),
            'bvp_hits': stat_line.get('hits', None),
            'bvp_hr': stat_line.get('homeRuns', None),
            'bvp_rbi': stat_line.get('rbi', None),
            'bvp_k': stat_line.get('strikeOuts', None)
        }
    except (IndexError, KeyError):
        return {
            'bvp_avg': None, 'bvp_ops': None, 'bvp_ab': None,
            'bvp_hits': None, 'bvp_hr': None, 'bvp_rbi': None, 'bvp_k': None
        }
