62 Sam Tuivailala RP

Tuivailala (Achilles) had surgery last Wednesday in San Francisco and is facing a 6-to-8-month recovery timeline, Greg Johns of MLB.com reports.

The right-hander was only able to log five appearances with the Mariners following a move from the Cardinals at the trade deadline before suffering his injury. The organization had visions of Tuivailala serving as a valuable multi-inning option out of the bullpen, but given that his return isn't likely to come until after the start of the 2019 season, he won't have a chance to start paying dividends again for quite some time.

Tuivailala (Achilles) was transferred to the 60-day disabled list Tuesday.

The move is procedural, as he's been ruled out for the season and potentially part of next year with a strained Achilles. He'll vacate the 40-man roster, making room for Robinson Cano's return from the restricted list.

Tuivailala (Achilles) could miss part of the 2019 campaign following season-ending surgery, Greg Johns of MLB.com reports.

Tuivailala was placed on the 10-day disabled list Thursday due to a strained right Achilles, and it was later determined that he'd need to go under the knife. His status for the beginning of spring training is now up in the air, as manager Scott Servais stated Tuivailala will miss "significant" time, per Johns. A clearer timetable for Tuivailala's return should surface when next season approaches.

Tuivailala is expected to require season-ending surgery on his Achilles, Ryan Divish of The Seattle Times reports.

Tuivailala hit the 10-day disabled list with a strained right Achilles on Thursday and the injury appears to be a significant one. He appeared just five times for Seattle after being shipped from St. Louis in late July. Assuming his season is indeed over, the 25-year-old will end the year with a 3.41 ERA in 37 innings of relief.

The Mariners activated Tuivailala on Sunday, Greg Johns of MLB.com reports.

Tuivailala will join the big club right away after he was acquired from the Cardinals on Friday. The 25-year-old has posted so-so results (3.69 ERA, 1.45 WHIP in 31.2 innings) out of the St. Louis bullpen this season, but his mid-to-upper-90s fastball makes him an enticing relief prospect for Seattle. He'll likely see most of his work in lower-leverage spots initially.
