Seth Halvorsen delivers clean inning in win

Seth Halvorsen fired a scoreless inning, allowing no hits or walks in Tuesday’s 3-2 win over the Marlins.

Fantasy Impact

Halvorsen continued his efficient relief work, holding the line for Colorado with a clean sixth inning. The 25-year-old now holds a 4.38 ERA and 1.46 WHIP through 24.2 innings in his rookie campaign. He’s shown flashes, but with low strikeout totals and limited usage in key spots, Halvorsen’s fantasy relevance remains minimal outside of deep NL-only formats.

Seth Halvorsen competing for closer role

Seth Halvorsen is competing in camp to open the season as the Rockies closer.

Fantasy Impact

Halvorsen threw live batting practice on Thursday. He recorded two saves last season with a 1.46 ERA across 12 1/3 innings. The Rockies closer won't be super valuable, but any closer is worth rostering in deeper leagues.
