Houston Astros outfielder Kyle Tucker is not in the starting lineup for Sunday's game against the Tigers. Tucker has not been the lightning in a bottle that everyone expected him to be so far, but it's still early. Mike Trout didn't do so hot when he first came up either. Though it is concerning that he also sat on Thursday and hasn't produced yet, there is still a lot of upside for him. At this point, it's tough to start him in a weekly league as his isn't playing everyday or producing, but he is still a top prospect and a must hold.
