The Rockies were looking to replace Clint Barmes as their starting shortstop after his tough 2006 season, so they gave their #1 prospect according to Baseball America a shot to compete for the starting job.  Troy Tulowitzki outplayed Barmes and earned the starting job.  He had a tough start, but he seems to be settling into the job.  In 45 games this season, Tulowitzki is 45 for 171 (.263 avg, .708 OPS) with 24 runs scored, 2 homers and 20 RBIs.  The Rockies hope Tulowitzki keeps up the good work.
