Martin has a 112 wRC+ for the season, which is pretty good. He did have an ABYSMAL August (38 wRC+) but he has bounced back nicely this month and is sporting a 118 wRC+ for September.
Now this is pretty far off his 141 wRC+ of last year, but I don't think many people here expected him to hit that well again this year.
Martin has been great this year, although he was pretty banged up in August and it definitely showed.
