This may be a stupid question. Since Trevino has put tape on his left thumb, this can assist the sensing of the pushing on the left thumb #1 pp, is this legal? Since this is a kind of assistance or training aid. If it is leggal then why those specify glove is illegal?
My hypothesis is that Trevino puts the tape on his thumb to keep the glove from wearing out in that spot. I find that hitters wear that spot out more than most.
