Clase will start in left field and bat eighth in Monday's game versus the Reds.
Clase will make his MLB debut after he was recalled from Triple-A Tacoma earlier Monday after outfielder Dominic Canzone (shoulder) was placed on the 10-day injured list in a corresponding move. According to Shannon Drayer of Seattle Sports 710 AM, Mariners manager Scott Servais said Monday that Clase will play while he's with the big club, so it sounds like he could see the lion's share of starts in left field while Canzone is out. The 21-year-old has slashed .311/.396/.622 with two homers, three steals and a 12:7 K:BB with Tacoma this season and is worth a look in deeper fantasy leagues.
