The one area on the Rangers' roster that seems like it could be a prime candidate for an upgrade is left field. Travis Jankowski hasn't been bad, but his upside is limited by an iffy track record with his hit tool and not hitting for much power to speak of basically ever. Thankfully, the top prospect in Texas' farm system could be the answer as Evan Carter is loaded with tools and could be on the verge of making his big league debut.
Carter looks like an absolute heist as a second round pick out of the 2020 draft as he is loaded with tools including a plus hit tool, the ability to hit for power, and he can really run. Through 94 games in the minor leagues this season, Carter has slashed .276/410/.448 with 13 homers and 22 stolen bases. Putting him in left field is kind of a waste as he is a strong defender at all three outfield positions, but Carter's bat and upside is too much to resist in the name of optimization. Texas could start him off at Triple next season and let him play his way into a promotion, but don't be surprised if he gets a long look as an option right out of spring training.
Okay, okay...it is definitely weird to include Leiter as he hasn't played in an official game since being placed on the development list in mid-July. However, Leiter's arm talent is too much too ignore here. Both his fastball and slider are plus pitches that get plenty of swing and miss and while his curve and changeup lag behind, they still can serve as at least change of pace pitches.
The issue, of course, is the command issues Leiter had in Double-A which is the likely reason why he got put on the development list so that he could work on his mechanics in a more controlled setting. Assuming those adjustments are made, Leiter already has some experience in the upper minors and with better command, he should be on the fast track to the big leagues where there should be opportunities for him to win a big league roster spot in 2024.
