MLB Injury List Update

One thing to note for all the fantasy baseball injury news you may hear is what type of IL the players are being placed on. There is still a COVID IL (a few players have already been placed on it). Vaccinated players with close contacts have no minimum stay. Non-vaccinated players still need to stay around seven to 10 days on the IL. The current MLB IL remains at 10 days. Starting this week, the IL will be 10 days for hitters and 15 days for pitchers. One can learn a lot about the players' current injury based on which IL they get put on. Teams will be placing injured players on the 60-day IL to create for themselves more roster flexibility as those players do not count against the active 40-man rosters. More importantly, if a player is hurt and is placed on the 15-day IL, the team then believes that the player will be back sooner than the 60 days, or the mid June.

Also of interest, MLB will allow rosters to have 14 pitchers on their active rosters through May 29, and then the limit of 13 pitchers will take affect. This will go into the thinking of Major League teams when calling up players for injured ones. When picking up and dropping players, keep that in mind.

Injured Hitters for Fantasy Baseball

Ronald Acuna Jr. (OF, ATL) - Knee: Acuna was activated off of the IL on April 28. The question that surrounded him when he was coming back was whether he is healthy enough to start stealing right when he comes back. Acuna answered that with two stolen bases in his first game back. He may only play every other day to start until he builds up the stamina to play every day. 

Teoscar Hernandez (OF, TOR) - Oblique: Hernandez was placed on the IL with a left oblique strain. This week, he began hitting in the cage against a high-velocity machine. This is the first step to his return but there is still no timetable for his return. Raimel Tapia or Bradley Zimmer will continue to benefit with more playing time for the Blue Jays.

Jose Altuve (2B, HOU)- Hamstring: Altuve was placed on the IL with a strained left hamstring. He is currently on a rehab assignment and is expected to be activated this week, maybe Monday.

Luis Urias (3B, MIL) - Quad: Urias injured his left quad running the bases earlier this spring and is yet to play this season. He is on a rehab assignment and should be activated from the IL this week.
