Career
Erlich made his Grand Slam debut at the 1995 Wimbledon Championships, entering the main draw as a lucky loser. He was defeated in the first round by German Arne Thoms, in straight sets. Three years later he qualified for his second Grand Slam, the 1998 United States Open, but exited again in the opening round, losing to 20th seed Michael Chang.
On the Association of Tennis Professionals Tour he was more successful as a doubles player and with partner Noam Behr reached the final of the 1996 Eisenberg Israel Open, as wild cards entrants.
His best wins perhaps came in the doubles, with victories over the Àlex Corretja and Emilio Sánchez combination from Spain as well as the Dominik Hrbatý and Karol Kučera pairing from Slovakia. Doubles: (3).
