Mariners Outright Justus Sheffield

The Mariners announced that left-hander Justus Sheffield has cleared waivers and been outrighted to Triple-A Tacoma.

Sheffield, 27 in May, was a first round draft pick and was previously considered one of the top prospects in baseball. Selected 31st overall by Cleveland in 2014, went to the Yankees in 2016 as part of the Andrew Miller trade and then went to Seattle in the 2018 James Paxton deal. Baseball America placed him on their top 100 list for four straight years beginning in 2016, including placing Sheffield in the top 50 for the latter two years of that stretch.

Unfortunately, he hasn’t been able to deliver on that hype so far. He’s pitched 186 innings in the big leagues over the past five seasons with a 5.47 ERA, 18.2% strikeout rate and 10.6% walk rate. His 49.5% ground ball rate is strong but the results have been poor otherwise. His work in the minors hasn’t inspired much confidence either, as he registered a 6.99 ERA over 24 Triple-A starts last year.

Those poor results nudged him off the roster when the Mariners signed Tommy La Stella last week. None of the 29 other clubs were willing to commit a roster spot to Sheffield so he’ll stick with the M’s as non-roster depth. Players with over three years of service time or a previous career outright can reject an outright assignment and elect free agency, but Sheffield doesn’t meet either qualification. If he earns his way back onto the roster, he still has one option year remaining.
