This puzzle was a delight.  The removal of "in" in the long answers and replacing it with the key noun, places the noun literally 
in the answer --- clever.  And there were so many
GOOD ONES!"Remote location?"    SOFA
"Musician's forte?"   LOUD [
forte means loud]
"Hot rod rod"   AXLE
"Green dispenser"    ATM
"Thumb"    HITCH [...a ride.  I was thinking nouns.]
"Corn site"   TOE
"Blue books?"   SMUT [not the college test variety]
"Debugging application?"    DEET [active ingredient in insect repellant]
"Pitches between innings?"    ADS
I noted two sets of answers which might have been linked:  APERY and MIMIC [copy]; OAKY and CASK [wine].
I loved this puzzle despite its use of ACER which is never used in tennis.  As I mentioned about a month ago, ACER is a major computer company.
