You are correct: my thoughts were for the team at full strength, where it will be Yuli at first, Alvarez at DH, Tucker at RR and White somewhere else.
Yeah, sorry I wasn't clear about what Kaplan was saying, it was more scatter-shot the way I presented it. Yup, Tucker is not a factor this season because, to put it bluntly, Alvarez passed him in terms of being called up... and even to a lesser extent, so did Fisher. Fisher doing well and having a good short stint in the majors bodes well to him being traded (for both him and the team). Tucker is not going to advance this year, but he'll be in the mix next year.
So to talk about the long term (re: rest of the season):
CF - Springer (1)
3rd - Bregman (2)
LF or 2nd - Either Brantley or Altuve (depending on Hinch) (3rd)
LF or 2nd- Either Brantley or Altuve (depending on Hinch) (4th)
DH - more than likely Alvarez's best lineup position (5th)
SS - Carlos Correa if he stays away from a masseuse, chiropractor, santeria witch doctor or a professional wrassler (6th)
1st - Yuli (7th)
C - Chirinos (8th)
RF - Reddick (9th)
Hinch other players to get spots starts in that lineup
Kemp gets some time in the outfield and DH and bats 9th. If Kemp DHs, then Alvarez goes to LF or Kemp goes to LF and Alvarez stays at DH and Brantley gets some time off or Reddick does.
White? He may be gone by then. Trade fodder or DFA'ed.
Marisnick - he has a ton of value to allow Springer, Brantley and Reddick time off to rest their legs. He'll bat in those spot starts somewhere in the bottom of the order with everyone moving up a notch. Basically, Marisnick with his slugging prowess is probably a #8 hitter when he plays.
Diaz - he is going to replace White in the roster and take up playing time at 2nd, SS, 3rd and 1st to spell all of those guys. Kemp will still get time at 2nd so Altuve can rest the legs more often by taking a day off or hitting in Hinch's merry-go-round DH spot.
Straw? Probably going back to AAA because he has options and really with Kemp, Diaz and Marisnick (not to mention Stassi who is the second catcher), that is your bench for the rest of the season. If they decide to carry one less bullpen pitcher, then you can keep either White or Straw, but I don't see that happening.
