— SF Giants on NBCS (@NBCSGiants) September 5, 2026 In all, Flora allowed one hit, walked one batter and struck out two while throwing 28 pitches.

The Giants are taking a cautious approach with Flora after he threw 102 innings for UC Santa Barbara this year.

San Jose wraps up the 2026 regular season this weekend before beginning the California League playoffs next week, so it’s possible Flora makes another abbreviated start.

For now, the 21-year-old can celebrate a solid start to his professional baseball career.
