The 34-year-old Erlich slammed a volley from close to the net to return a Bopanna shot from the baseline to enter the final and set up a title clash with either third seeded Indo-Serbian pair of Leander Paes and Janko Tipsarevic or the all-American duo of Rajeev Ram and Scott Lipsky.
In a match that lasted about 90 minutes, the Indian pair wasted a breakpoint in the seventh game of the second set to go 4-3 up, following which Erlich and Ram won three games in succession, including game seven, to wrap up the set 6-3 and take the match into the tie-breaker.
In the tie-breaker, Erlich and Ram took the lead in the fifth point of Bhupathi's serve, when Erlich placed a serve return on the line. They went 6-4 up after Erlich rushed upfield after serving and placed a volley that the Indian pair could not return.
