10 months to get back into playing shape

I quit playing ball 4 years ago and would like to be ready for a college wood bat league next summer. How should I go about getting back into playing shape by that time. Since I quit my conditioning is pretty awful but I’m much stronger. I’m not sure how long I should wait to start throwing again or what my workout regimen should entail.

A quick google search lead me to this

Day 1: Legs and Abs

Squat: 4 sets of 15 reps
Stiff-Leg Dead lifts: 3 sets of 12 reps
Hamstring Curl: 3 sets of 12 reps
Leg Extension: 2 sets of 10 reps
Walking Lunge: 2 sets of 20 steps
Leg Lifts: 1 set of 30 reps
Crunches: 2 sets of 15 reps
Oblique Twists: 1 set of 25 reps
Reverse Crunches: 1 set of 30 reps

Day 2: Arms and Chest

Close-Grip Bench Press: 4 sets of 8 reps
Flies: 2 sets of 12 reps
Tri Pushdowns: 3 sets of 10 reps
Skull Crushers: 2 sets of 12 reps
Overhead Dumbbell Extension: 3 sets of 10 reps
Tri Pull downs: 2 sets of 8 reps
Forearm Curls: 4 sets of 10 reps
Wrist Curls: 4 sets of 10 reps

Day 3: Shoulders and Back

Bent rows: 3 sets of 15 reps
Back Extensions: 3 sets of 25 reps
Wide Grip Pull-ups: 1-Failure
Lateral Raises: 2 sets of 12 reps
Machine Rows: 2 sets of 8 reps
Cuban Press: 3 sets of 12 reps

I might try it with a lot of running on my off days and gradually being a throwing program. Any recommendations would be greatly appreciated.
