Mariners Moose Tracks, 3/21/20: Red Sox sign-stealing, Padres TJs, and Aaron Judge’s lung

Despite what your body clock says, this is indeed Saturday.

• The Mariners optioned four players to AAA-Tacoma yesterday: INFs Donavan Walton and Patrick Wisdom, as well as RHPs Zac Grotz and Taylor Williams.
• They also released likable RHP reliever Sam Tuivailala. Despite good results last year, Tuivailala was reportedly 85-87 mph on his fastball this spring and clearly not at full strength.
• Something to keep an eye out for on FanGraphs.

Around the league...

• The Red Sox appear to know of MLB’s ruling in their involvement with sign-stealing cheating and disagree with the ruling, per reporting by Daniel Kaplan of The Athletic.
