Giants Draft UC Santa Barbara Ace Jackson Flora No. 4 Overall

Flora blossomed from UCSB bullpen to a frontline starter, a trajectory that MLB observers expect could lead to a quick rise through the minors.
His pitching mix includes a mid-to-upper-90s fastball that can reach triple digits, plus a gyro slider in the upper-80s, a slower sweeper around 80 mph, and a changeup, with all primary offerings graded around 55 and well-commanded.
During UCSB's season, Flora racked up a school-record 133 strikeouts in 102 innings and had a stretch of 38⅓ scoreless innings, highlighting his dominance beyond the surface numbers.
Flora grew up as a Giants fan in Pleasanton and attended Foothill High School; he even cited Brandon Crawford as a big influence, underscoring his local ties to the franchise.
The pick marks the Giants’ first top-five selection since 2018 (Joey Bart) and positions Flora among a lineage that includes Will Clark, Matt Williams and Buster Posey as notable top-five alumni, underscoring the franchise’s long-standing history of developing impact players.
The San Francisco Giants used the No. 4 overall pick in the 2026 MLB Draft to select UC Santa Barbara right-hander Jackson Flora, the consensus best starting pitcher in the class. NBC Sports Bay Area reported that the Giants added a potential ace to a farm system in serious need of pitching talent.
Flora, 21, is a Bay Area native from Pleasanton who grew up a Giants fan. He attended Foothill High School before starring at UCSB, where he set the school's single-season strikeout record. The pick carries a slot value of $8,988,400, according to Sacramento Bee.
Flora was nearly untouchable in his final college season. He threw 102 innings, struck out 133 batters, and posted an ERA between 1.03 and 1.06, according to UCSB Gauchos. He also put together a stretch of 38⅓ consecutive scoreless innings, a run that underscored just how dominant he was.
Flora made the jump from UCSB's bullpen to a frontline starter this season. That transition impressed scouts. MLB Pipeline ranked him as the top pitching prospect in the entire draft class, per NBC Sports Bay Area.
Flora's fastball sits in the mid-to-upper 90s and can touch triple digits. He pairs it with a gyro slider in the upper 80s, a slower sweeper around 80 mph, and a changeup. NBC Sports Bay Area noted that all of his primary pitches grade around 55 on the scouting scale and are well-commanded.
At 6-foot-5, Flora has the size scouts love in a starting pitcher. His four-pitch mix and frame are the main reasons experts believe he could move quickly through the minor leagues on his way to San Francisco.
Flora is the Giants' first top-five selection since catcher Joey Bart went No. 2 overall in 2018. He is just the sixth player in franchise history drafted in the top five. Past top-five Giants picks include Will Clark (No. 2 in 1985), Matt Williams (No. 3 in 1986), and Buster Posey (No. 5 in 2008), per New York Post.
UCSB also has a strong track record of producing high-end MLB talent from its pitching staff. UCSB Gauchos noted that Flora is the first Gaucho pitcher to be selected this high in the draft, continuing the program's reputation as a pipeline for pro-ready arms.
Growing up in Pleasanton, Flora rooted for the Giants and looked up to shortstop Brandon Crawford as a big influence. Sacramento Bee reported that Flora cited Crawford as someone he admired, giving his selection a personal layer beyond pure baseball.
Other top picks in the 2026 draft included Roch Cholowsky and Grady Emerson, per San Luis Obispo Tribune. But Flora stood out as the clear top arm. For the Giants, landing him at No. 4 — a player who grew up dreaming of wearing orange and black — made the pick feel like more than just a transaction.
