Oh, absolutely! I do a lot of drills on court involving sprints as well. Before every practice I try to get in 10-15 minutes of movement drills.
I'm just wondering about aerobic training and what kind of distance a player should train for. I can jog a 5k right now, at a mediocre speed, but I'm curious if I should try to improve my 5k time to sub 21:00 or if I should start working on being able to run a 10k. I'm not yet at the point in my tennis experience to be playing full three set matches so I'm not sure how much aerobic capacity one requires.
Here's what one USTA coach says about "running":
"When training the players the USTA works with, we usually do some sort of "running" four to five times a week. The running session usually lasts between 20 – 40 minutes, but there is a lot of variety in the types of running we do.
You’ll note that we put running in quotation marks, because much of what we do is different from the long, slow distance running many tennis players are familiar with – there is some long distance running, but the “running” sessions also involve footwork/tennis agility work, or interval runs. The type of running depends upon the periodized strength and conditioning schedule of the player.
Generally, the long distance running and longer interval repeats (400s and 800s) are done during the preparation phase when you are getting ready for the season. Shorter, higher intensity intervals (20s, 40s, 60s, 100s, 200s, and 400s) and on-court footwork/tennis agility are the main focus during the pre-competition phase in the weeks leading up to main competition or competitions. During the competition phase of the season, on-court footwork/tennis agility is the “running” focus.
Recognizing that each player is an individual, we adjust the plan depending upon the player’s cardiovascular endurance, agility and their physical and physiological strengths and weaknesses."

I am puzzled by your statement, "I'm not yet at the point in my tennis experience to be playing full three set matches so I'm not sure how much aerobic capacity one requires."
That is, do you still need lots of practice to maintain an extended rally, or do you need a lot more practice to hit forehands and backhands on the run?
If so, even though having better fitness is a goal, you may want to concentrate on playing more tennis to improve your tennis skills and work on your conditioning at the same time.
Extended hitting sessions using 6 balls and keeping the ball in as continuous play as possible may be your best bet for both improving your tennis and working on conditioning at the same time.
This is a good time of year with long evenings to get in extra tennis.
And if you have trouble finding a hitting partner some night, you can get in a pretty good workout against the wall:
