LL’s Top 50 Mariners Prospects 2020

A year ago when writing this list, we hadn’t seen Jarred Kelenic play a game as a Mariner, Logan Gilbert throw a pitch as a Mariner, nor Julio Rodriguez play a game stateside. George Kirby, Isaiah Campbell, and Brandon Williamson were all gearing up for what would be their last season of college baseball and trying to keep draft chatter at a minimum. Noelvi Marte hadn’t played a single pro game. The Mariners farm system was still regarded with a healthy dose of skepticism by almost everyone in the industry, including the fanbase, many of whom were quick to invoke the names of failed prospects of the past or suggest not to get too attached to this new crop before “DiPoto [sic] trades him.”

But a year later, the shape of the next Mariners team is starting to come into sharper focus. Mariners prospects are popping up in tweets, articles, and even on MLB Network, led by Kyle Lewis’s majestic homers, Justin Dunn’s informative and entertaining analysis of his pitching mechanics, and Julio’s thousand-watt smile. Evan White signed a contract extension with the club that made him the de facto Opening Day first baseman. The lineup card at T-Mobile Park is slowly beginning to fill with the names of the future.

If you haven’t followed the minors in years past, this is a great year to get started. As in years past, we will have plenty of in-depth coverage of the minors this year, written from the perspective of a group of people deeply familiar with and invested in the Mariners and their development—something the major prospect sites can’t offer. Our Mariners prospect list goes up to 50 to help you learn the names and faces of the players who will populate this year’s Midshipman’s Log, our multi-weekly roundup of the minors that pulls information and analysis (and video, where possible) from across the system. So whether you are a prospect maven or new to the world of the minors, we will provide you information and a space to discuss all Mariners prospects, all the time. We’re excited for the future, and excited to have you with us.
