Green was released by the Nationals last week after appearing in 40 games with Triple-A Syracuse this season, where he slashed .246/.319/.285, but failed to make much of an impact on his overall stock. Over 129 career games with the A's, Angels, Giants and Nationals, the 29-year-old has compiled a .246 average and 38 RBI while mainly being used as a reserve infielder. He'll serve as organizational depth for a White Sox team already dealing with injuries to Tyler Saladino and Leury Garcia, but remains a longshot to see much, if any, major-league playing time.

The Nats designated Green for assignment earlier in the week but Green will remain in the Washington system, having passed through waivers unclaimed. A first-round pick in 2009, Green is merely an organizational depth piece. He has totaled 353 plate appearances in parts of five seasons at the major-league level (97 plate appearances since the start of the 2015 season).

With Trea Turner (hamstring) returning from the disabled list, Green was the obvious casualty. The 29-year-old received barely any playing time during his short stint with the Nationals, going 0-for-3 in his only start Thursday. Green likely returns to Triple-A Syracuse if he clears waivers, where he should see regular playing time and further chances to hone his skill set.

Green is the beneficiary from the Nats' sudden void at shortstop, as Trea Turner and Stephen Drew are both sidelined by hamstring injuries. The former first round draft pick is off to a rough start this season, batting .162 over 20 spring games and .154 over four games with Triple-A Syracuse, but provides major league experience at the position. Nonetheless, he needs to find some rhythm at the plate if he wants to remain with the team long-term.
