TJ Rumfield's Power Outbreak Offers Hope Amid Average Slump

Rockies everyday first baseman TJ Rumfield has hit a brief slump, batting just .118 over his last seven games, though he did crush a clutch go-ahead homer on Wednesday. The last-place Rockies (26-42) continue to run the rookie out daily, especially with Tyler Freeman sidelined on the injured list. Rumfield is fully healthy after avoiding a hand fracture in late May and remains locked into the starting lineup.

His recent cold spell shouldn't panic managers, as he is still batting a robust .275 with an .858 OPS over his last 30 days. This mirrors our season projection of a .275 average and 10 home runs, as well as his solid .273 career mark. The underlying metrics suggest his high-contact approach is sustainable, making this current dip a buying opportunity.

Colorado wraps up its series against Chicago today facing Edward Cabrera (4.99 ERA) before heading to Oakland for three games. While A's starter Gage Jump (2.45 ERA) poses a tough test, matchups against Jeffrey Springs (4.68 ERA) and J.T. Ginn (3.26 ERA) are highly exploitable. Given his everyday role and upcoming matchups, he is a recommended option. Verdict: Start.

Outlook Peter Lambert

Hand injury clouds Peter Lambert's solid run in the Astros' rotation

Peter Lambert has pitched well recently, posting a 2.78 ERA over his last 14 days, but he is now questionable after suffering a hand injury during his June 10th start. He currently slots in as the number four starter for the fourth-place Astros, who are looking to snap a two-game losing streak. His status for his next turn remains highly uncertain.

While Lambert's 3.52 ERA and 1.23 WHIP through 56.3 innings this year represent a massive step forward from his rocky career in Colorado, our models expect some regression. Our season projection points to a 4.00 ERA and a 1.30 WHIP rest of season, suggesting his recent hot streak is playing slightly above his true baseline.

Having already made his lone scheduled start of the week on Wednesday against the Angels, Lambert has no remaining matchups on the schedule this week. With the hand injury threatening his upcoming availability, fantasy managers should look elsewhere. Verdict: Sit.
