What does Addison Russell mean for Starlin Castro?

The Chicago Cubs brought up young shortstop phenom Addison Russell to the big league level. What does that mean for Starlin Castro? 

The Chicago Cubs are bringing up the talent from the minor leagues to help the big league club. They recently brought up Kris Byrant to play at third base and to take some hacks in the middle of the lineup. He is already making an impact to the lineup with 4 RBI in his first 4 games in the league.

Now the team is bringing up another top prospect to the big league level with the call up of shortstop Addison Russell, according to Jon Heyman. Russell has been ranked the No. 2 rated prospect going into the 2015 season by Baseball Prospectus and is expected to hit in the big league level. He will come up to play second base for the Cubs. He is an accomplished shortstop though and likely would be the best defensive shortstop on the roster.

People now wonder what this means for Starlin Castro and his future with the Cubs? Is he on the trading block? Will he stay at shortstop defensively?

At the moment, it seems too early for the team to put Castro on the trade block. There are a number of teams that would love to get his bat in their lineup if he were to become available. With Castro up at the big league level, the Cubs started getting Russell prepped to play some second base. Castro and Russell will work together for the time being in the middle of the infield. At some point, Russell is expected to take the shortstop position though. He is just too good defensively at the spot and would give the team the defensive talent that is needed to play the spot.

If the Cubs look to keep Starlin and Russell in the lineup for the long-term, they could continue with the two in the middle infield or they could move Russell over to short and Stalin can move to third base with Bryant moving to the outfield. That seems like a lot of movement for the young players on the Cubs.

If the Cubs were unable to hang in the standings, we could see Starlin dangled out there in some trade talk. He is a solid bat for lineups and teams would love to add him onto their roster. He could bring in more young talent for the Cubs to bring onto the roster and allow their top prospect to play at his natural position.
