The major challenge in this puzzle was sussing a theme, which appears to be four items found at the end of fill, which do not appear by themselves when eaten (i.e, they're always in plural form). I may be all wrong as after some 200 puzzles write ups, I just am not sure. I blogged Jacob's first publication last year (a quote theme) and see he has had a NYT as well as another here in March since then. The long fill was the theme and reveal, but there also were: AMENITY, ASIATIC, LABELED, ORATION, GO TO SEED, HABITATS which are nice. Remarkably few proper name references so this should be doable by most. Left handed reliever Jesse Orosco was probably the most obscure along with the YMCA reference to Geneva but I know baseball and the perps were easy because it had to be a place, so it was all good. I also do not want to rock the boat, so let us head out into the sea of clues/fill.
