Solid and sometimes novel cluing make for a entertaining Tuesday offering.
I hadn’t seen ‘contact’ and ‘old vice’ in these senses before, both supplying those necessary ‘aha!’ moments that keep us engaged. Good fun: a slow start but mostly write-ins from about the half-way point. Thanks to Sleuth.

*anagram
‘Preserve’ in 1ac is def, I think, and. ‘prepared’ gives SET.
Yes, solid — a steady solve, one corner at a time. Thanks, Sleuth and GB.
Thanks, Rishi. Oops, slip of the eye-brain interface. Typed ‘pre’ and switched off. The def is correctly underlined though.
I completed in short time but had trouble parsing27 across and 2, 4 and 7 down. In 16d, I think you meant A N(ame) LOCATED . Thanks both.
I missed the ‘contact’ and ‘old vice’ wordplay – both very good – and (just being thick) couldn’t see ONTO for ‘virtually dominant’. TOTTING-UP for ‘problem for a driver?’? I thought it was a bit vague and also wondered about the use of the hyphen.
I would describe a good (usually fast) bowler as being a ‘strike bowler’ rather than as a ‘striker’. The use of ‘strikers’ can be justified by a batsman facing the bowling as being ‘on strike’.
I liked the answer-as-clue PIN-UP and the apt 6d anagram.
Thanks to Sleuth and Grant
Thanks to Sleuth and Grant. I was slowed down by some UK items (TOTTING-UP, Sale-Manchester) and had trouble parsing PIN-UP, but I enjoyed this puzzle.
Thanks Sleuth & Grant.
In cricket the batsmen strike the ball. The confusion in parsing 11 across may have arisen because the opening batsmen usually face fast bowlers.
Thanks Sleuth and Grant
A tricky little puzzle in parts, especially with the same ‘local knowledge’ clues mentioned by acd@6 that were both new to me. Forgot to go back and see if I could properly parse both PIN-UP and IDLENESS and don’t know whether I would have been able if I had.
Did have an ‘aha’ moment when Joe BIDEN surfaced for ‘vice’ at 24a and thought that it was quite a clever bit of deception. Liked EYE-OPENER and TORONTO (when I finally got the ON TO[P] bit … wasn’t as enthused about DEEP SEA’s definition.
Finished up the top by correcting SET ASIDE (from PUT ASIDE) after seeing SLOPPY at 1d and that PIN-UP was the last one in.
