People need to stop these "Duda/Alonso" stopgap suggestions that would only lead to an eventual grievance from the union and make Boston a less desirable stop for other free agents).
All HRam has to do is play well in 2018,an d he'll get his 497 PAs, even with Duda and JD on the 25 man roster.
He may file a grievance, if he sucks next year and misses out on 497, but he won't win. I'm not buying the idea that serious damage will be done to the Sox image, in terms of future free agent signings. If HRam sucks in 2017, it will be basically 3 out of 4 years falling short or way short of expectations. A team should be able to make plans to mitigate serious problems on their teams.
He is having surgery, so signing someone good as insurance should not be an affront to HRam. Like I said, if HRam stays healthy and plays well, he can and should still get over 500 PAs next year.
JD Martinez plays the OF whenever any of them needs a rest or gets hurt. That should be at least 100 PAs in the field. If JBJ keeps struggling, he may get more "rest" than is needed, so that number could be closer to 150 that 100 PAs with zero OF injuries. JD has only played more than 123 games once in his career. He's only gotten over 517 PAs once. That being said, let's assume he gets 650 like he did this year. That's 150 in the OF and 500 at DH. That leaves about 200 PAs at DH and 700 at 1B. That's 900 PAs total for Duda and HRam to split, assuming absolutely no injuries at LF, CF, RF, 1B and DH (highly unlikely). If HRam can't play well enough to get 500 out of those 900 PAs, then he has no beef.
If he plays well, and we still keep him from getting 497, then he has a beef. I doubt we bench him, if he's doing better than Duda and JBJ (or even Beni vs LHPs).
