I believe he'll have the opportunity to earn a starting role. I don't think he's quite there yet. I think he'll share time in a rotation between LF and CF. Kiké will probably due a 50/50 split with CF/2B. Arroyo has been pretty good so I don't see him being benched.
Kiké has a 746 OPS after starting off ice cold. He has a 914 OPS over the last 30 days. Odds are that Duran will not have a 900 OPS.
He's the LFer of the future. Similar to how some people wanted to project Beni as a CFer. Duran just isn't that good there.
Kiké will play more than Duran going forward. Santana is off the roster for now.
Duran won't play 2b. He hasn't played there at all since the beginning of the 2018 season for Lowell.
His defense isn't ready and he can't hit away from Polar Park. He may be ready though. I would have brought him up when they demoted Cordero. These aren't mutually exclusive opinions.
Some are speculating Kiké to 2b, Duran to CF. I don't think they are going to make Duran and fulltime guy right now. I think he'll get a lot of opportunities, but play about 50% of the time unless he really forces their hand.
