We talk a lot about the importance of hip internal rotation for bowlers
And here is a small article from the epic guys at cressey performance to back it up, they have the same issues for their baseballers

Lead Hip Internal Rotation is important for mobility in the baseball player.
Even though a baseball is thrown with the arm/upper body, the lower half of the body and the trunk play a major role in velocity, accuracy, etc.
Limitations in lead hip internal rotation can create compensations at the hip, pelvis, and in turn, the upper body.
Limitations here can place increased stress on the lumbar spine as well as the elbow and shoulder. Lead hip would be considered the left hip on a right handed thrower and the right hip on a left handed thrower.
We like to see at least 30 degrees of hip internal rotation in sitting and in prone. I
f there are limitations in mobility in either sitting or prone, this can be due to capsular or bony limitations.
It can also be due to soft tissue limitations in the adductor muscles and hip internal or external rotator musculature.
If there are limitations in either motion, try performing self-myofascial release to the aforementioned muscles or seek out a physical therapist or a massage therapist to address those areas.
Many times with overhead athletes, assumptions are made that the problem may be at the elbow or shoulder.
Make sure to assess the lower body, specifically lead hip hip internal rotation mobility, to make sure the body isn’t compensating further up the kinetic chain.
Some great points
We did a webinar for the Inner Circle guys about how we test the internal rotation with our fast bowlers
