In casual American English, "He hit a home run and ran around all the bases" sounds like "hee HIHT uh HOHM RUHN and RAN uh-ROWND AHL dhuh BAY-suhz". Several things happen here, and the headline one is the Consonant-to-Vowel Linking: the consonant links forward into the next vowel without a pause. Keep stressed words long, unstressed words short, and link the consonants forward into the vowels.

What makes this sentence sound American.
The "" at the end of "run" flows directly into the vowel starting "and" — the consonant migrates to the next word with no pause between. This is called the Consonant-to-Vowel Linking, a connected-speech trick that makes phrases flow. It comes out as RUHN.

Small tricks that turn a textbook sentence into how an American actually says it.
Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
Pronouncing the vowel before M/N too pure.
In "and", the "a" vowel before M or N raises and fronts toward [eə] — the tongue pulls up and forward, breaking the vowel into a tense glide as it anticipates the nasal. The "/æ/" vowel raises and fronts before M or N — tongue pulls up and forward, producing a tense [eə] glide (between /e/ and /ə/). Not a pure /æ/.
Treating every L the same.
The L in "all" is a dark L — the back of the tongue rises toward the soft palate, adding a small "uh" quality before the L. Dark L adds a small schwa-like "uh" before the L. The back of the tongue lifts toward the soft palate.
Hard T at the end of a word, not a flap.
The "t" at the end of "" links to the vowel starting "" — it flaps to sound like a quick "d", with the tongue briefly tapping the ridge behind the upper teeth. Same flap as within-word (R1) but spanning two words.
Pausing between the words.
The "" at the end of "" flows directly into the vowel starting "" — the consonant migrates to the next word with no pause between. Final consonant "migrates" to next word — no pause between.
