Baseball Star uses the Baseball Cannon as his primary weapon, which deals 3-7 impact damage and 4-8 critical damage based on distance. The Baseball Cannon fires faster and is more accurate than the All-Star's primary weapon. As expected, this leads to faster overheating. It compensates for this by having a shorter overheat penalty.
An alternate ability of Dummy Shield, the Future Dummy is stronger than the default Dummy Shield, but only one Future Dummy can be placed down at a time. When the Future Dummy is destroyed, it explodes (dealing up to 75 damage to nearby Plants).
Weapon upgrades
Baseball Star's Weapon Upgrades
Chilled Baseballs
By chilling the baseballs the day before, the overall heat tolerance is increased.
Super Zomboss Fans
By installing tiny Zomboss fans, the venting of an overheat moment takes a little less time.
Lead Filled Baseballs
By injecting the balls with lead, the baseballs hurt more causing more damage.
Unlocking (Garden Warfare only)
Baseball Star is unlocked by reaching level 10 with the All-Star. Each level after 5 will reward the player with a single character piece until all are unlocked at level 10.
Strategy
With
The Baseball Star has a high fire rate, thus overheating quickly. Use him at close range, as you can potentially deal up to 350 damage, enough to vanquish any plant. If you keep a prolonged volley of baseballs hitting your opponent, it will either vanquish or heavily injure them, depending on the class's base health and how much health they had prior to their encounter with you. Do not use him at long range, as although he seems to play like the Golf Star, his damage fall out is severe, crippling his damage to half of his close-range hits. Remember to fire in short bursts, as if your weapon overheats, you are a sitting duck to enemy Cacti, and an easier vanquish for the other plants. If your weapon overheats while fighting, use your Sprint Tackle or Imp Punt to finish your opponent. If on low health, place a Dummy ShieldShield Decoy and dash to the side or wait until the plant comes to you, in which case use your abilities to take them out.
Against
Be wary of any Baseball Stars in medium range of you, as they can inflict heavy damage or downright vanquish you if they are accurate, with the possibility of this being exceptionally high for Sunflowers and Roses and less so for Citrons, Corns, and Chompers. As a Cactus, you can safely pick off health from the Baseball Star from long range and put up a Tallnut Battlement to block any weakened shots sent your way. If you are playing as a Peashooter and a Baseball Star attacks you head-on, keep in mind that he has enough health to survive your Chili Bean Bomb and is fast enough to outrun the Sombrero Bean Bomb. If your aim is true, fire a Shuck Shot as a Corn to vanquish him immediately. Pea Gatlings, Time Snares, EMPeaches, and Sunbeams are effective at lowering his health or stunning the Baseball Star.
