MIAMI (AP) — A week ago, the Boston Celtics were too old.
Three games later, they're one win away from the NBA finals.
And Miami — the team that was constructed with hopes of supplanting Boston as the power in the Eastern Conference — is suddenly in big trouble.
Kevin Garnett finished with 26 points and 11 rebounds, Paul Pierce scored 19 — including a huge 3-pointer over LeBron James' outstretched arm with 52.9 seconds left — and the Celtics beat the Heat 94-90 on Tuesday night, taking a 3-2 lead in the East finals that now shift to Boston for Game 6 on Thursday night.
