Brendan Donovan has been using TheStack for over a year to build real, measurable bat speed gains. After his first program last year, he saw a +4 mph increase in bat speed on his way to his first All-Star Game. Good things happen when you trust the science & dedicate yourself to the craft. Donnie works hard, stays consistent, and we couldn’t be more proud to have him on board as an official Stack Athlete!

The next step is having players understand how to efficiently increase their bat speed. The science of speed matters. Good thing we know a guy… @SashoMacKenzie

The fact that the idea of “swinging the bat faster is better” is considered new age analytical thinking is insane. Gaining speed/power/force production has been beneficial for every athlete in every sport since the beginning of time. Pitchers who throw harder have higher

Brendan Donovan is having his best season yet. He’s locked in on a great mindset: “Warm up to hit — don’t hit to warm up.” - He trains movement patterns to gain speed without losing the swing that makes him elite

#Statcast Aging Curve for Swing Speed (updated with 2025 data) I also included quasi-best-fit line, which you can play around with as more data comes in. This line in vertex form (which is much much much easier to understand than off-putting quadratic): -.02*(Age - 25.5) + 72

Bat speed sets your ceiling

You need to move the bat fast if you want to hit the ball hard. According to math, this is how fast you need to be able to move the bat to reach these exit velocity thresholds.

Bobby Witt Jr: What do you use for your mental game? • I look at my bat, find a little focal point, take a deep breath + say something like ‘IT’S TIME’ to get the juices flowing • Having a consistent preparation routine in dugout, on-deck & in the box each day

@danpadilla51 Have them train for bat speed on the days they are not with you. Monitor their data & review in person if needed. When you’re with the hitter, focus on mechanical improvements, bat to ball skills, mental approach, and take as many live ABs as possible.
