Sebastian Caseres - 4/30/26

Another lesser known Angels arm – 18-year-old Venezuelan lefty Sebastian Caseres. Silky smooth delivery and advanced feel for spin. Thin/wiry build but plus athlete with standout body control and a loose arm.

You know those prospects who (SEEMINGLY out of nowhere) show up next spring throwing 5 mph harder? Caseres checks a lot of those boxes. He’s listed at 5’11” 148. I thought closer to 6’ and 165-170 lbs. Regardless – this kid doesn’t have his man muscles yet.

In love with the delivery. Easy/repeatable mechanics. Well-timed rotation and good balance – head very still through landing with no recoil. Compact arm circle. Easy on-line follow through with finish in good fielding position.

Only pitched one inning but pounded the zone with fastball/slider combo. Slider flashed plus with late break/tilt. Able to land in zone or chase with intent. Makeup read – works at a deliberate pace. Seems calm, cool, collected. Low pulse vibe. Body projection, athleticism and smooth delivery you can really dream on. Would like to see in a longer outing and a 3rd pitch. Really intrigued by this short look. On my follow with keen interest list.
