At this point in the season there are four players on UConn's 35 man roster who have not played in a game this season, so at this point it is probably safe to think that these players are redshirting the season. The one position player redshirt candidate is sophomore Andy Hague, who was previously reported as recovering from an injury. The other three redshirt candidates are freshmen. They would be outfielder/pitcher Adam Schwartz, and pitchers Tyler Briggs and Tim Pfaffenbichler. It is not unusual for UConn to have a few young pitchers redshirting in any one season. Sometimes they are recovering from injury, other times the coaching staff is just looking for time to have these players develop their skills.
You just never quite know what will happen with players who are redshirted. Sometimes they just disappear from the roster over the summer or in the following season or so. Other times they become a big part of the team in succeeding years. Caleb Wurster would be an example of the latter, along with Carson Cross, who became perhaps my wife's favorite UConn pitcher. A different type of redshirt would be Paul Gozzo and Karl Johnson, both of whom had to sit out last season due to transferring into UConn from other schools.
