Out of the nearly 1700 players who have appeared for the Red Sox through the 2013 season, there have been almost 800 players that have worn a Boston uniform for just a single season. Some may be remembered for one fleeting moment in the spotlight, like Billy Rohr, who was one out away from a no-hitter against the New York Yankees in his first major league start in 1967 but made just eight more starts that season and won only one other game (his next start, also against the Yankees). Others may have been aging former All-Stars looking for one last season under the sun, like Carlos Baerga or Mark Lemke.
Then there are those who use that one season to showcase their talents, performing at a level perhaps unexpected. Every plate appearance seems to produce, every play in the field seems fluid and flawless, and the sportswriters and fans watch in awe and amazement.
