The 24-year-old has joined the Baggies on a two-year contract for a £50,000 fee, and Martis said: "I did not play as well as I could last season but I was ready to fight hard for my place this time around, I was determined to work hard and play much better, but the gaffer at Hibernian was not giving me the confidence I needed and I was starting to get the feeling it was not going to work out."
