Jarlin Susana may not be in the running for an Opening Day roster spot, but the 20-year-old righty is certainly putting on a show at spring training.

The Washington Nationals pitching prospect took the mound for the third time in Grapefruit League play Saturday against the St. Louis Cardinals. He entered the contest in the eighth inning, looking to preserve a 2-2 tie.

That's exactly what he did, using blazing speed to get the job done.

Susana's first pitch of the afternoon was a 100.1 mph fastball. After issuing a four-pitch leadoff walk, Susana recorded a strikeout and a flyout, capping off the latter at-bat with a 102 mph pitch.

Although he walked the next batter he faced, Susana worked his way out of the jam by forcing an inning-ending lineout on a 101.5 mph fastball.

In all, Susana threw four pitches that hit triple-digit velocity.

Susana has thrown 3.0 innings so far this spring, not allowing a run. He has given up one hit and four walks compared to three strikeouts.

MLB Pipeline had the righty ranked as the No. 2 pitcher and No. 4 overall prospect in Washington's farm system at the end of 2024. Susana enters 2025 as a consensus top 100 prospect, with Baseball Prospectus slotting him in as the No. 47 prospect in baseball.

Susana went 4-10 with a 4.34 ERA, 1.312 WHIP and 13.6 strikeouts per nine innings in 103.2 innings between Single-A and High-A in 2024. He improved his strikeout-to-walk ratio to 3.27, compared to his 1.55 mark the year before.

The Nationals went on to lose 3-2 Saturday after one of their other pitching prospects, Marquis Grissom Jr., gave up a walk-off single in the bottom of the ninth.
