Years of Eligibility left

You have 10 full-time (12+ hours) semesters to play four years in. Be careful if you take summer or winter term hours too, those count towards either fall or spring semesters. I ran into that issue, I took a year off and just did studies before playing juco. When I was recruited to a NCAA D2 school, they looked at my transcript and told me I only had 1 semester of eligibility left. Basically I shot myself in the foot when I thought I was getting ahead with my credits. I ended playing far a NAIA team...

So, your redshirt counts as 2 semesters (assuming you were there the whole school year), your playing counts for another 2 semesters (under sam assumption). Assuming you do not enroll in any full time semesters until you start playing again, you will have six more semesters (3 years) of eligibility.

Another question about this subject.  My son took a medical redshirt his first year at 4 year school due to surgery.  Is going to juco, played 3 games and got hurt after the third game.  How many years/semesters does he have left?  Can he take another year redshirt? 

Medical Redshirt Rules

• A baseball player may also be redshirted for medical reasons. These reasons  include baseball-related injuries as well as unexpected illnesses and conditions  such as cancer. A baseball player may apply for two medical redshirts during his  or her college career. If a player has already received a redshirt for  non-medical reasons, that player may apply for only one medical redshirt.

  The rule allowing for two medical redshirts is particularly useful in college  baseball because arm injuries to pitchers can require more than a year to  properly heal. By using two medical redshirts, a college pitcher can take his  time in recovering from arm surgery.  This allows the player to return at full strength.

Removing a Redshirt

• Once a redshirt is issued to a baseball player, that player is not banned  from playing that season. A team can choose to remove a player’s redshirt at any  point during the season, but regardless of when the redshirt is removed, that  player loses an entire year of eligibility. Even if the player steps on the  field in the very last inning of the last game of the year, that player loses  the entire year of eligibility. College baseball teams don’t often remove  redshirts from player during the middle of the season, but it usually occurs  when an active player suffers a long-term injury and must be  replaced.

I'm uncertain if since he played 3 games, and then was injured, if the redshirt tag would apply. Maybe contact his coach and see if he was able to receive his second medical redshirt.
