March 29, 2025 9:23 PM : Halvorsen was perfect Saturday, striking out one without allowing a baserunner to secure a four-out save against the Rays.
Analysis: Halvorsen averaged 99 mph on both his fastball and sinker, needing just 14 pitches to secure the Rockies' first save opportunity of the season. The 25-year-old impressed late in 2024 with a 1.46 ERA in 12.1 innings and made a strong case for more save chances with his sharp 2025 debut.
