San Diego's closer over the last two seasons, Suarez is likely to begin 2026 setting up Raisel Iglesias in Atlanta. He relies heavily on his fastball, which averaged 98.6 mph last season along with a 98.4 mph sinker.

Velocity has never been a problem for Stanek, who has nine years of MLB experience. However, he posted an ERA above 5.00 with the Mets last season, and hopes to get back on track as a Cardinal this season. His fastball averaged 98.6 mph in 2025.

A huge increase in velocity helped Schlittler become a star last season, posting a 2.96 ERA in 14 regular-season starts. His four-seam averaged 98 mph last season.
