My doubles partner and I have fallen into a predictable pattern of match play lately. The majority of our matches, whether playing at the 3.5 or 4.0 level, have gone to a third set tiebreak. We usually come out blazing and have great first sets. We usually end up winning the matches but here is a sample of our latest scores: 3.5 match 6-1,3-6, 1-0 (10-2 tb) and 4.0 match 6-1,6-7,1-0 (11-9 tb). This is starting to get into my head and I feel myself getting tight from the get go of the second set. Lately, we've been saying to each other "think of the first set as a warm-up or pretend we are starting a new match". We try to stick to our original game plan but things seem to take a complete U-Turn in the second set. The winning volley's my partner made in the first set are now going long or getting dumped into the net. I start spraying my service returns or double faulting. We both get tight knowing that the number of our unforced errors is adding up and we are now down a service break or two. We know we should be focussing on one point at a time and continue to be positive and supportive of each other, but frustration does creep in before you know it. Although we are generally happy to be able to close out the match in the tiebreak...we would like to try to make it easier on ourselves and close it out in 2 sets. Any advice, mental or tactical, would be appreciated.
