Los Angeles Angels star Shohei Ohtani has been out since June 6, and it remains unknown when he can return to the field.

Manager Mike Scioscia said the two-way player would be re-evaluated in two weeks for the sprained ulnar collateral ligament in his right (throwing) elbow that caused him to be placed on the disabled list, according to Bob Nightengale of USA Today.

The medical staff is "very optimistic" about Ohtani's health, although it remains possible he will still need Tommy John surgery, which would end his season, per Nightengale.

Bill Shaikin of the Los Angeles Times added that the 23-year-old has been taking one-armed swings in the batting cage while awaiting a prognosis.

Scioscia said last week the Angels would consider letting the rookie hit if he can't pitch, per Jeff Fletcher of the Orange County Register.

The Japanese star was one of the most exciting players in baseball over the first couple of months of the season. He excelled as a pitcher, posting a 4-1 record and a 3.10 ERA in nine starts, striking out 11.1 batters per nine innings.

On his non-pitching days, Ohtani served as the designated hitter and batted .289 with six home runs and 20 RBI in 34 games.

Unfortunately, his elbow injury has kept him off the field and the Angels are struggling without him, losing six of their last seven games.

While the medical staff remains confident he will return this season, there appears to be a lot of unknowns going forward.
