Mariners Notes: Thomas, Sheffield, Dunn

The Mariners have outrighted Dillon Thomas, according to a club announcement.

The outfielder was initially selected by the Rockies in the fourth round of the 2011 draft. After a decade in the minor league systems of the Rockies, Brewers and Mariners, the 28-year-old was finally selected to a big league roster earlier this year. Unfortunately, he was only able to play four games, accumulating nine plate appearances, striking out in seven of them and getting one hit. His Triple-A numbers this year are solid, slashing .273/.379/.458, good enough for a wRC+ of 110.

Other notes from Seattle…

• Justus Sheffield will begin a rehab assignment tomorrow, according to Jen Mueller of ROOT Sports. Sheffield has been out almost a month with both a flexor strain and an oblique strain. Before going on the IL, Sheffield was struggling to replicate his solid 2020 season. After 55 1/3 innings of 3.58 ERA ball last year, the lefty has logged 73 2/3 innings this year with his ERA having ballooned up to 6.48.
• Mueller also provides an update on Justin Dunn. Though this one is not as encouraging, as Dunn has not begun throwing off a mound yet. The righty has been on the IL since mid-June with a shoulder strain. The 25-year-old was enjoying a breakout season before the injury, throwing 50 1/3 innings with an ERA of 3.75. He had also increased his strikeout rate and reduced his walk rate, compared to last year.
