The first day of the draft has come and gone and the Mariners took a conservative tack with their first three picks, going with high-floor college arms at 20, 59, and 77. While Elon’s George Kirby was a consensus first-rounder and Arkansas’ Isaiah Campbell was well-regarded as a comp-to-second round choice, TCU’s Brandon Williamson was viewed as a stretch at 59; he was listed at 83 on MLB Pipeline, 86 on Baseball America, and all the way at 138 on FanGraphs. This might indicate that Williamson will agree to sign under slot value, and with Kirby and Campbell most likely signing at or slightly underslot, that should free up some money for the Mariners to splash on an intriguing prep prospect.
