The organization says in its statement that Seager is “expected to resume baseball activities in January.” That would seemingly make it possible for him to participate fully in Spring Training.
Of course, that timeline is somewhat tighter than seems preferable. Seager has already been out for over three months and was experiencing some hip problems just before his elbow ligament popped. It obviously would have been preferable to use that time to rehab both issues. Presumably, there’s an explanation, though it hasn’t yet been given publicly.
Seager, 24, has been a high-end performer since breaking into the league at 21 years of age late in the 2015 season. He had not been in top form in the early stages of the 2018 season, though that might well have changed with a hot streak. All said, Seager carries a .302/.372/.494 slash with 54 home runs through 1,528 MLB plate appearances. He’ll be eligible for arbitration for the first time this fall, though his ill-timed health problems will significantly dent his expected earnings.
