The Mariners optioned Diaz to their spring training complex Monday.
ANALYSIS
The move makes room on the Mariners' 28-man active roster for right-handed reliever Gregory Santos (biceps), who was reinstated from the 15-day injured list. Diaz had made two appearances for the big club since being recalled Sept. 1, allowing one hit and one walk while striking out three over 3.1 scoreless innings.

2023 Fantasy Outlook
Diaz spent most of 2022 in Triple-A, where he posted a 4.98 ERA, 1.36 WHIP and 46:20 K:BB over 47 innings. For a second straight season, he got a brief taste of the big-leagues, hurling 15.1 innings over four outings (three starts) and recording a 2.93 ERA. While that number looks good on the surface, Diaz gave up four walks in each of his first two appearances and logged a troubling 11:10 K:BB overall. Diaz doesn't throw hard -- he averaged 91.4 mph on his fastball last year during his time in the majors -- but he throws five different pitches, using all but his curveball at least 16% of the time last season. The slider was clearly his best pitch, as he threw it 44 times to big-league hitters during the campaign without giving up a hit while posting a 40.6% whiff rate on the offering. The southpaw ended the campaign on the 60-day IL with an undisclosed injury, and Los Angeles designated him for assignment in November before re-signing him to a minor-league contract the following month. He'll likely open the 2023 campaign back at Triple-A but should see some time in the majors at some point during the season.
