When the Padres made Coleman Borthwick their first-round selection in the 2026 Draft, scouting director Chris Kemp cited the 6-foot-6 hurler’s “track record of domination” as being a big part of why the club nabbed him 21st overall.
That belief also led to the organization turning to its No. 3 prospect to make his pro debut during Single-A Lake Elsinore’s 6-1 win over Ontario at The Diamond on Thursday night, helping the club advance to the California League Finals, which will begin Sunday night. Shortly after being drafted, Borthwick struck a refrain that’s sure to earn him brownie points among Padres fans:
“I’m ready to go beat the Dodgers,” he said in late July.
While Thursday wasn’t exactly taking on the two-time defending World Series champions, it was their Single-A affiliate. And Borthwick helped to send them packing.
Borthwick was thrust right into the fire, facing a bevy of ranked Dodgers prospects. He struck out his first two batters -- Kellon Lindsey (LAD No. 13) and Ching-Hsien Ko (LAD No. 12) -- and yielded just one run over two innings. His fastball was clocked as high as 98 mph and he picked up three of his four punchouts on his heater, one of his two pitches that grades out as a plus offering.
The other? His 60-grade slider. The breaker sat in the mid 80s and got some funky swings from Ontario batters, including Conner O’Neal, who struck out on one in the dirt in the seventh. Already equipped with a feel for spin from his days on the Florida high school circuit as an amateur, Borthwick should neutralize righties and lefties alike with his slider, which darts away from same-side hitters and darts in on opposite-side ones.

San Diego has been on quite the run of selecting high-upside high schoolers with their first selection for 10 years running. Borthwick relieved left-hander Kruz Schoolcraft (SD No. 2), the club's top selection in the 2025 Draft, who turned in arguably his best outing of the season with eight strikeouts across five scoreless frames.
Both teenage hurlers boast impressive raw ingredients to go along with their respective natural size -- Borthwick at 6-foot-6 and 245 pounds, Schoolcraft at 6-foot-8 and 229 pounds. It's a large part of why they rank as the club's top pitching prospects, giving a look of its best duo since the days of Robby Snelling and Dylan Lesko earlier this decade.

Borthwick and Schoolcraft might seem far away from contributing to the big leagues, but look no further than the last time Lake Elsinore took home a California League title for a reminder of how quickly prospects -- especially top-tier ones -- can emerge on the scene. In 2022, the Storm shellacked the opposition en route to a crown, led by a young shortstop prospect named Jackson Merrill; four years later, he already has an MLB All-Star Game appearance and Silver Slugger to his credit.
