With another outstanding themeless, Ms. Weintraub is INRAREFORM. I found very little to PRESS her on.
My error came at 18A: Analagous (AKIN). I tried AsIN, which in my support, is often found in an analogy. But the excellent 12D: Place where lots of calls are made (POKERTABLE) finally put me right. I love that clue for its distinct and clear absence of a question mark.
Other clues of note include 37A: What can get batters out? (SPATULAS) - didn't fool me for a minute, although I did think of "ScraperS" first. Also, I liked 31A: One might be by the water cooler (WORKMATE). And also 39D: Knocks loudly? (BERATES). Some fine work there.
The triple stacks in the NW and SE corners are both very good. Starting with BARBIEDOLL above AVERAGEJOE and 17A: It gets you what you need (LIVINGWAGE), I love the contrasts in gender and presumed socioeconomic status. The other triple is not as strong, but I do like ROLLERRINK.
The more I review this puzzle, the more I find to enjoy. I'll leave you with one last outstanding clue and answer. 50D: A cameo may have one (LINE). As in one single line. That's brilliance, my fine readers.
UPNEXT? Well, whoever it is has tough shoes to fill.
