Collector Trivia & Player Notes

* This is Spencer Giesting’s official 1st Bowman Autograph, the first flagship certified autograph issued for the Diamondbacks left-handed pitching prospect.

* Giesting was selected by the Arizona Diamondbacks in the 11th round (318th overall) of the 2022 MLB Draft out of UNC Charlotte.

* He reached Double-A Amarillo during the 2024 season, continuing his steady climb through Arizona’s farm system.

* While pitching for High-A Hillsboro in 2024, Giesting posted an impressive 1.50 ERA with 10.1 strikeouts per nine innings, earning Northwest League All-Star honors.

* Giesting throws from a deceptive three-quarter arm slot, making his fastball and breaking pitches difficult for hitters to pick up.

* His arsenal features a sweeping slider, an upper-80s cutter, and a high-70s breaking ball that generates swings and misses.

* MLB Pipeline has ranked him among the Diamondbacks’ Top 30 prospects, recognizing his continued development as a starting pitcher.

* At 6’4”, Giesting has the durable frame clubs look for in a professional starting pitcher.

* Current update: Giesting continues pitching in the Diamondbacks’ system as one of Arizona’s more advanced left-handed pitching prospects and remains on the radar for future upper-level success.

* As a 1st Bowman Auto, this card represents the earliest licensed certified autograph available for one of Arizona’s better left-handed pitching prospects.

* Left-handed starters with upper-level success and swing-and-miss stuff have historically generated strong hobby interest as they approach the major leagues.
