Arizona Diamondbacks' Top Prospect Provides Cautionary Tale For Seattle Mariners

In this story:
Seattle Mariners' top prospect Cole Young put together a massive five-hit night for Triple-A Tacoma on Wednesday, and with the M's offense struggling, the calls for him to get promoted are growing louder and louder.
However, perhaps the Arizona Diamondbacks' top prospect, Jordan Lawlar, serves as a cautionary tale and a reminder to the M's about the perils of promoting top prospects.
Lawlar is ranked as the No. 4 prospect in the sport by MLB Pipeline and is hitting .336 at Triple-A this season. He went 0-for-19 in eight games at the big league level and was sent back down Thursday by Arizona, showing that even red-hot prospects aren't instant successes at the next level.
Top prospect Jordan Lawlar has been optioned to Triple-A by the Diamondbacks, per @Gambo987.

For comparison, Young is hitting .277 this season and is the No. 43 prospect in baseball. Perhaps the M's just don't want to put Young through the major leagues until they know he's ready, and they don't think 52 games at Triple-A is enough to say that yet.

I want to see Cole Young promoted, but for the "can't be worse than current guys" people, Jordan Lawlar was having a better season in the same league as Cole Young is a top 5-10 prospect and a year older. Went 0-19 https://t.co/puEbeafWKl

There's also the issue of roster construction and how Young fits into the big-league roster, which we wrote about here.
As for the Mariners themselves, they enter play Thursday at 30-24 overall and in first place in the American League West. They lead the Houston Astros by 0.5 games and will take on the Washington Nationals Thursday at 6:40 p.m. PT.
