In hindsight signing Martinez to another 4 year contract was foolish, 2 years would have been much more appropriate, considering that he couldn't even play 1B much anymore, and that he was becoming ever slower on the basepaths.
I would offer him an extra $2 million, if he would agree to retire and annuitize the last year of his contract to $5 million per year over the next 4 years.
Christin Stewart looks like Adam Dunn in the K and BB categories, than HR. He could top 200 Ks moreso than hitting 40+ HRs, the latter @ least for a couple of seasons. Being a LH batter with some power is an asset, being poor defensively is a big liability. Put him on the bench as a PH and PT DH.
HRs by Aaron Judge in the minors his last 3 years (through age 24):
17, 20 and 19
.261 BAVG .345 OBP .465 SLG .810 OPS 24.4 PA/HR
HRs by Christin Stewart in the minors last 3 years (through age 23):
10, 30 and 28
.262 BAVG .363 OBP .508 SLG .871 OPS 20.6 PA/HR
And based on his 2017 Strike out rate, Stewart would have to get over 800 Plate Appearances to strike out 200 times.
Why is it so many are reluctant to give a kid a chance? I am not saying he will have a season like Judge.

Compare Stewart's last 3 years with any other player's last 3 years through 23 or 24, and they compare at the extreme high end. Yes, he is a liability on defense. But in LF, or maybe even eventually 1B, that liability is negligible compared to the offense he could provide.
He won't hit more than say .250, but his OBP should be about 100 points higher than his BAVG. There is no reason to not believe he hits at least 30 HRs on a regular basis. Again, Adam Dunn is a fair comparison and that isn't a knock on him at all.
