Elizegi, Barrena, and Enrique often overserve when their singles games are on....These guys have monster "speed serves" for lack of a better term. Hard and low with a ton of velocity that are very difficult to even catch when in the corner and certainly hard to return with any kind of offense...problem is they start getting closer and closer to the over line - which all too often happens after 2 or 3 successful ones - like at game point..ouch
