Ketchup is pronounced /ˈkɛtʃəp/. Its first syllable /kɛtʃ/ matches the words ketch, sketch, fetch, stretch, and wretch (all with stressed /ɛtʃ/), but none rhymes with the whole word because the extra final /əp/ is missing. Catch looks similar in spelling but is pronounced /kætʃ/, with /æ/ instead of /ɛ/.
