Round Four (107): Mariners select Ryan Webb. LHP Georgia

Ryan Webb is yet another prototypical #4 starter who hasn’t actually been used as a starter at Georgia. The 6’1″, 195 lb lefty has an average fastball that sits in the low-90s and has touched 95 at times and a fringe-average changeup he doesn’t use much. The separator for Webb and why he has a chance to start in the big leagues are his two breaking balls.

The curveball sits in the high-70s with good depth and the slider flashes plus, which is especially impressive considering he just started throwing it in 2020. There are some concerns surrounding Webb, who may go undrafted as a result.

His control is best classified as fringe-average. His delivery is rigid and lacks fluidity, contributing to his control issues. He missed a large chunk of the 2019 season with a sore arm and prior to 2020, he had only been a modestly successful pitcher in the SEC.

There isn’t much upside to Webb, but the floor is that of a solid, multi-inning reliever, similar to former Mariners lefty Mike Montgomery. By selecting Webb in the early fourth round, Seattle might be able to squeeze some savings by going under-slot, which could be a part of the plan to sway Masyn Winn from his Arkansas commitment.
