Yamamoto announced Monday via his personal Twitter account that he has decided to retire from professional baseball.

EDGE Analysis

Yamamoto's decision comes just one week after the Dodgers reassigned him to minor-league camp after he was unable to claim a spot on the team's Opening Day roster. The 26-year-old right-hander made 21 appearances (19 starts) in the majors from 2019 through 2021, logging a 6.05 ERA and 1.41 WHIP across 96.2 career innings between the Marlins and Mets. Yamamoto struggled mightily in 2022 in stops with three of the Mets' minor-league affiliates, and rather than facing the likelihood of another year on the farm in the Dodgers organization, he's elected to close the door on his playing career.

Yamamoto signed a minor-league contract with the Dodgers on Tuesday.

EDGE Analysis

It's not clear whether Yamamoto has been given an invitation to major-league spring training. The 26-year-old spent all of 2022 in the minor leagues with the Mets, with his most extensive action coming at Double-A Binghamton where he posted a 4.55 ERA over 31.2 innings.

Yamamoto cleared waivers Monday and was outrighted to Triple-A Syracuse, Anthony DiComo of MLB.com reports.

EDGE Analysis

Yamamoto owns a carer 6.05 ERA in 96.2 major-league innings, so it's no surprise to see him go unclaimed on waivers. He'll remain in an organizational depth role in the minors for now.

The Mets designated Yamamoto for assignment Tuesday.

EDGE Analysis

Yamamoto failed to land a spot on the Mets' Opening Day roster, and he'll now lose his spot on the 40-man roster ahead of the regular season. If he goes unclaimed on waivers, he'll be a candidate to provide rotation depth this year if the Mets' pitching staff deals with additional injuries.

Yamamoto was re-assigned to the Mets' minor-league camp Friday, Joe Trezza of MLB.com reports.

EDGE Analysis

The right-hander wasn't expected to break camp on the big-league roster anyway, but the quick exile is likely due to the shortened spring training schedule and a lack of innings for the Mets' established arms. "We need to get him stretched out," manager Buck Showalter said regarding Yamamoto's demotion. The 25-year-old should begin the year at Triple-A Syracuse and could see action in the majors later this summer if injuries force the Mets to dip into their rotation depth.

Yamamoto (shoulder) was activated off the 60-day injured list Friday and optioned to Triple-A Syracuse, Tim Healey of Newsday reports.

EDGE Analysis

Yamamoto had been out since late May with a sore right shoulder. He'd been pitching at the Triple-A level while on a rehab assignment and will now remain there as a normal member of the team.

Yamamoto (shoulder) had his rehab assignment transferred to Triple-A Syracuse on Saturday, Anthony DiComo of MLB.com reports.

EDGE Analysis

Yamamoto allowed one run on three hits and no walks while striking out five in four innings at Low-A St. Lucie last week, and he'll now progress to the top level of the minors. The Mets haven't yet announced when the right-hander will be able to return, but he'll likely be in the mix to be activated sometime next week.

Yamamoto (shoulder) made his most recent rehab start at Low-A St. Lucie on Thursday, working four innings while striking out five and giving up a run on three hits and no walks.

EDGE Analysis

Now four starts into his rehab assignment, Yamamoto has made his last three turns with St. Lucie after kicking off his minor-league stint in the rookie-level Florida Complex League. He's continuing to build back up for a starting role in case the Mets require an extra arm for the rotation later in September, but Yamamoto is more likely to slot into the bullpen if the big club suffers no further attrition to its pitching staff in the next week or two.

Yamamoto (shoulder) began a rehab assignment with the rookie-level Florida Complex League affiliate Friday, Anthony DiComo of MLB.com reports.

EDGE Analysis

Yamamoto has been on the injured list since late May due to a sore right shoulder, but he resumed mound work in mid-July. The righty tossed a scoreless inning during his first rehab appearance and will likely require several appearances in the minors before he rejoins the major-league club. However, Yamamoto should be available as a starting option for the Mets if they need one in September.

Yamamoto (shoulder) has been throwing bullpens in Florida and could move toward a rehab assignment soon, Mike Puma of the New York Post reports.

EDGE Analysis

Yamamoto has already missed nearly two months with right shoulder soreness. His return isn't imminent, but it looks as though he'll be back well before the end of the season if he can avoid setbacks.
