What happened: MLB Network's MLB Tonight crew poked fun at Brandon Nimmo's arm muscles during a broadcast segment. The remark came as a lighthearted aside rather than part of game analysis.

Why it matters: The bit fits MLB Tonight's recurring habit of ribbing players outside live action. Nimmo's path to the majors has drawn its own coverage beyond his on-field performance.

What to watch: No further detail on the segment has surfaced.
