Arm Health - Essential Metrics

Do You Know These Essential Arm Health Metrics?






The number one question parents, players, and coaches ask is...

“How can pitchers maximize velocity without hurting their arm?”

There are a lot of opinions on this topic, such as pitch counts, the impact of certain pitches like curve balls, and pitching mechanics, but when it comes down to it, there is little to no evidence that those things actually reduce the risk of harm.

Instead, the priority should be on these four primary factors that will ensure a player’s health and keep them progressing to the next level. 

1. Fatigue - Does a player lose significant strength after a bout of high-intensity throwing?

Fatigue is the number one cause of injuries and poor performance in athletes, particularly in sports that involve repetitive and high-intensity movements like pitching.  

Fatigue is best measured by assessing changes in strength that occur after an outing. When the muscles become fatigued, their ability to generate force and stabilize the joints effectively decreases. As a result, a pitcher may see drops in velocity & accuracy.  

Proper conditioning and training programs that address strength can help a player better withstand fatigue during games and practices.  And objectively measuring fatigue with strength measurements can fine tune a players ideal pitch totals rather than a one size fits all approach.

2. Poor Recovery - Does throwing arm strength bounce back quickly?

Without adequate recovery, the throwing arm muscles and connective tissues may not fully repair and regenerate after intense training or competition.  

Insufficient recovery can lead to persistent weakness and soreness in the throwing arm, and increases the risk of overuse injuries, such as tendinitis, muscle and tendon strains, or stress fractures.  

Adequate rest, nutrition, hydration, and post-throwing recovery work are crucial for ensuring the throwing arm bounces back in strength for subsequent performances.

3. Weakness -  Is the throwing arm weak relative to the body?

An imbalanced strength ratio between the throwing arm and the rest of the body can lead to poor performance and injury. When the throwing arm is relatively weaker, it must absorb the strain from the rest of the body that’s pushing to its highest level.

To address throwing arm imbalance, athletes should focus on a comprehensive strength training program that hones in on the body's deficiencies, with extra focus on the specific demands of throwing.

4. Biomechanical Compensations -  Is there an increase in joint loading due to throwing delivery changes?

Compensations occur when athletes alter their throwing mechanics to correct for weakness, pain, or other limitations. These changes may lead to abnormal joint loading and cause excessive stress or torque during the throwing motion.  

Identifying mechanical issues has long been used to address throwing problems, but the approach usually misses the mark because it fails to address the underlying problem of needing enough strength to optimize delivery.

Key Health & Performance Metrics

ArmCare.com uses the following four strength based metrics to help coaches, parents, and players monitor and develop a high-powered arm.



1. ArmScore - total throwing arm strength expressed as a percentage of body weight (i.e., a score of 100 means that the athlete has a 100% of their body weight in throwing arm strength - a 200 lbs athlete would have a total of 200 lbs of strength.)

2. Strength Velocity Ratio -
total arm strength relative to the miles per hour that it can throw 

3. Fatigue Score -
total arm strength post pitching as a percentage of total arm strength in a recovered state (i.e., many highly developed players will have over 100, which means they get stronger after they throw.)

4. Recovery Score -
the change in total arm strength from recovered exam to recovered exam

Using these four measurements, the ArmCare App develops a personalized training plan to optimize health and maintain peak form of their throwing arm.

To learn more, ArmCare.com's Arm Health and Performance Level 1 course is the first-ever baseball certification course that uses arm strength measurements to personalize player development by addressing the most critical factors behind injuries.

2025 Year in Review: Draft We’ve reached the end of the 2025 calendar year, and while we’ve already jumped in on the 2026 cycle with some of the fall events and post-draft content we’ve had here at Perfect Game, there’s still one more piece on the docket, and that’s the 2025 Year-In-Review piece here from the PG Draft staff.  The 2025 MLB Draft took place in July, when many highly talented players heard their names called and continued their journey through the game to the next level. There’s already been some of those names making noise in the minors and guys who are moving up prospect lists and becoming names to know for MLB fans digging deep into the future of their organizations. While we are going to “close the book” on 2025 with this article, these players still have many years ahead of them, and many blank pages to continue...

Lucien Saint Cyr, INF, Class of 2026 Commitment: Bucknell Saint Cyr announced his pledge to Bucknell, giving the Bison an interesting blend of present tools and projection. Saint Cyr stands 6-foot-1 and offers room to fill in his medium frame, profiling in the middle infield defensively. The New York product starts wide at the base in the right-handed box, keeping his hands high behind the ear. He works into a subtle outward step load, firing through a compact barrel that showcases bat speed and gap-to-gap impact. For head coach Scott Heather and Bucknell, they land a high-quality Northeast infielder in the ’26 cycle, adding to a class that takes the quality over quantity approach. Patrick Diaz ('26, NY) 102 EV off the bat. Impact to the pull side. #PGNational @PGMidAtlantic @PG_Uncommitted pic.twitter.com/NN0L3FRdO9 — PG Showcases (@PGShowcases) July 9, 2025 Patrick Diaz,...

MVPitcher: Duncan McLeod The uncommitted junior toed the slab in three of the four games for Team Mick, tossing 3 2/3 innings.  Zero walks, zero hits and 6 punchouts for the lefty who was used both as a starter in the series clinching game 4 and he closed out game 3 on Friday in quick fashion.  McLeod was very efficient as well, needing just 42 pitches over all his outings.  In the game 4 start, over two innings he punched out 3, with one strikeout with all of his offerings.  The mid 80’s fastball regularly played up, set up with efficient use of the secondaries, with the breaking ball 73/74 and fading change-up 72-74.   Owen Bone (2026) at it again... Solo shot in the 5th to tie things up. Back to back days with a home run for Bone. #PGHS pic.twitter.com/2JC9qETI5h — Perfect Game California (@California_PG) December 13, 2025 MV Hitter: ...

13u Tourney All-American Team

What a year it was in 2025 on the national landscape at the 13u level as Perfect Game continues to expand its reach around the country, providing an even bigger schedule of events coast-to-coast which has allowed players all over show out and gain their deserved recognition. Whether in Texas for the Houston 1000 or the 13u WWBA in West Palm Beach, we saw huge, eye opening performances from the players placed below, knowing that we could EASILY build a third team and likely a fourth without much effort.  As we do every year with this exercise, it's worth pointing out the trickiness of this age group and putting the teams together with the 13u group. While the players are all members of the Class of 2030, some are younger for the grade, which allowed them to play at the 12u level where's it's a smaller field, shorter mound distance and different bats, so we'll separate them out and...

14u Tourney All-American Team

Player of the Year: Asher Williams It was an incredible year for Williams that was rewarded with a trip to the 14U Select Fest, before some more impressive play in the fall. He came to the plate almost 250 times in PG tournaments throughout 2025 and reached base in well over half of them, hitting to a .500 AVG while slugging a 14U circuit best 12 bombs and driving in 113 runs. The numbers on the surface are ridiculous, but when you look at the high-level events he put them up in, it makes it even more impressive. Pitcher of the Year: Tristan Blalock Blalock earns this honor after a dominant 2025 where he struck out 85 batters in just 48.2 innings of work with a minuscule 1.58 ERA. This included several strong performances at many national level tournaments and showcases where he was able to bully some of the best hitters in the country. It’s hard not to fall in love with...

PG Draft: Gut Feel Guys

Tyler Henninger
Article Image
While we are nearing the turn of the calendar to the 2026 year, that means we are just inching closer to the beginning of the season for many high school players and college baseball is on the horizon. We are prepping for a reshuffle of the 2026 MLB Draft Board as well here amongst the PG Draft staff. But before we get to that, we sat down and have each picked a couple of players who are in the mix to get selected in a couple of different buckets.  We have prospects who could go into the Top 30 picks or so, prospects who could be selected in the Top 5 rounds, and prospects who could go inside of the Top 10 rounds. With the draft quite far down the road and a lot of re-shuffling to be done as these players play themselves into certain spots on the draft board, our scouts picked some players who fit into these “buckets” who are gut-feel guys. These are the guys that our PG...

Hitter of the Year: Landon Bonner The 2028 class saw many players from across the country take the next step in their development as they entered the High School ranks. There were huge performances from highly ranked players on the PG circuit as well as some under-the-radar guys who burst onto the scene. Landon Bonner came into Sophomore National as a Top 500 ranked player and after an impressive showing, left with all eyes on him as a rankings riser in the class. The left-handed hitting shortstop from The Colony, Texas, had a summer to remember with All-Tournament Team selections in three of his next four events culminating with a historic performance at the 2025 PG 15U WWBA National Championship. The Hebron High School prep went 20-for-24 in nine games for 5 Star Mafia 15U Black with four homeruns and 12 runs batted in. He also scored 17 runs and finished with a mind-boggling 2.500...

16u Tourney All-American Team

Hitter of the Year: Koa Romero is the Hitter of the Year for the 16u group, as he would come to every premier event of the summer and earn All-Tournament honors (Beast of the East, 16/17u WWBA, Jupiter) in every single one. Over 82 plate appearances, Romero would pump ten homeruns with forty two RBI and sixteen walks, good for a .378 average and 1.339 OPS. The performance on volume at the best events of the year pushed Romero over the edge here, as he’d hit a pair of homeruns in Jupiter (one of them at 112 EV) as an underclassmen and collect double digit hits in BOTH WWBA events with a combined six jacks over the two tournaments. It was a summer that combined performance and winning on the biggest stages for Romero. It’s a quiet left-handed swing that packs a punch. He would reap the benefits of his performances, earning a commitment to LSU and jumping to the #74 prospect in...

They dip into Mississippi to land one of the premier arms and one that’s stood out on the circuit for quite some time. It’s a fast arm and the athleticism certainly shines working down the slope. The velocity has continued to tick up over the last calendar year and reached into the low-90s towards the end of the summer. He’s confident in his changeup and the breaking ball is...

There’s a lot of talent throughout this 2026 class, filled with the big-name stars, to talent that spreads across the nation. It’s been a lot of fun seeing these prospects grow and develop over the years, from the days of watching some of these guys at the 13/14u days at events on the circuit, to now where they are all graduating seniors in 2026. There’s been new faces who have popped along the way over the years, even in 2026, where some players who were relatively undiscovered, have come out and made a name for themselves with a statement performance. Between the familiar and the new, there’s a lot of names on this list that are going to be quite regularly talked about on the circuit, and for good reason.  Whether it’s PG All-Americans or not, there’s a lot of names with superstar potential at the next level. We’ve got 14 PG All-Americans...
