Greene began a minor league rehab assignment Thursday in the Arizona Complex League — his first live pitching since undergoing bone-chip removal surgery from his right elbow before the season. He has not thrown a single MLB inning in 2026. That context cuts both ways: it creates uncertainty, but it also means some managers have already dropped him for more immediate returns. In 2025, Greene was a legitimate SP2 with triple-digit velocity and a double-digit K/9 on full health. If he progresses through the AZL efficiently (typically 2–3 rehab starts before a higher-level assignment), a mid-July MLB return becomes plausible. Stash in any format where bench depth allows it — the ceiling is a top-20 pitcher returning in the back half.
