Stuck on two. Either may have a redundant word in the clue.
1ac. Hunt losing Queen in hand! Trace from greyhound? (3)
Looks like it should be DOG (I have DO?).
27ac. First lob hit with great force but never caught. (4)
I have L?UT and LOUT seems the only possibility.
The first clue looks like mutiple definitions but can't really parse it; in the second can't see a definition; L(first lob) + OUT (hit with great force) could be the word play.
Any suggestions much appreciated.
