The Mariners’ pitching prospects really showed out in their abbreviated spring training outings. Justus Sheffield was arguably the best pitcher on the staff in Arizona. Justin Dunn looked like a confident, big league starter with swagger to spare. And although he only threw 4 innings, Logan Gilbert flashed #1 stuff and, as such, is our #3 prospect in the Mariners farm system.
Gilbert, the 14th overall pick of the 2018 MLB draft, has long been thought to be a quick-rising, mid-rotation arm who had a chance. After missing his pro debut in 2018, Gilbert began the season in West Virginia and jumped to AA Arkansas in his first pro season.
