The right-arm fast medium bowler has represented England across all three formats and replaced Willey last summer to help the Scorchers claim their third KFC Big Bash Championship.
“The trend of the Scorchers getting players back who have been with us before has worked well in the past,” coach Justin Langer said.
“Tim was with us last year he’s a great professional and an outstanding bloke, when I told the players everyone was really excited because he’s the consummate team man.”
“It was a short turn around for Tim to get to Australia but he was happy to do it because I think he had such a great time last year. It was a bit harder to convince Hannah, his wife after just having their third child but it was great to get him back on board.
“We’ve said all along we would only get one international player this BBL, but after injuries to Nathan Coulter-Nile and Jason Behrendorff ruled them out of the season and then the exciting news that Jhye Richardson and AJ Tye will be leaving us for the ODI’s meant we had to look at another option.
“We’ve known our bowling stocks could potentially take a hit, we’ve got some great local talent that we’re confident in, but we just need to maintain the depth of our fast bowling.
“Having someone like Tim come into the Scorchers squad will be a welcome lift both on the field and off.”
