The modern game of baseball does not wait for the old guard to catch up. Every match up and pitch thrown has a statistical edge to one side or the other and the best teams are on the right side of that equation more often than not. Talent still matters greatly, but front offices and managers are tasked more than ever with putting that talent in position to succeed.

When interim general manager John Mozeliak swung the axe the week, dismissing world champion pitching coach Mike Maddux, bullpen coach Dom Chiti, and assistant pitching coach Darryl Scott, it sent shockwaves throughout the organization. Maddux is arguably one of the most respected, feel-based pitching gurus of the last two decades. His work developing the change ups of Jose Soriano and Walbert Urena are proof of his accumen.

Normally when a last place team fires on field coaching personell the front office is looking for a scapegoat. But in this case, the front office was signaling a shift away from old school feel and onto new school data.

The Tech Mandate: Adapt or Evaporate

For years under owner Arte Moreno, the Angels front office has routinely favored old-school baseball intuition over cutting-edge laboratory development. While franchises across the league built pitch-design infrastructure, Anaheim fell behind. With one of the smallest analytics staffs in Major League Baseball and an owner known for skimping on player development, the Angels were at a strategic disadvantage on the field.

Former GM Perry Minasian did pursuade Moreno to build a new pitching lab at the team's training facitily in Tempe in an attempt to bring the Angels into the analytical era. However, after investing in this resource he then hired Mike Maddux, a man known for old school methods, to run the pitching staff. This created a situation in which the team had more information available than it was providing to its pitchers and some of them were upset they were not being fully supported.

Mozeliak made the underlying tension explicitly clear following the firings. The coaching staff simply refused to adopt the tools provided to them by the front office. Maddux, known for mechanics-focused coaching, clashed with a front office mandating more data integration. The organization’s youth movement wanted access to modern tech like spatial analytics, which the veteran staff reportedly resisted

The St. Louis Paradigm Shift

Fortunately for Mozeliak, he had trusted pitching guru Tim Leveque already in the organization. The two knew each other well after spending two decades together in the St. Louis Cardinals organization. Leveque has greatly improved the AA Rocket City Trash Pandas arms this season and guided the breakouts of Luke Murphy and Joel Hurtado.

Leveque is also a huge fan of pitch data and knows the way Mozeliak likes it to be integrated into game planning. This hire is the first notable move towards a Cardinals West shift the entire Angels organization is likely going to take this off season.

Empowering the Youth Movement

As the Angels undergo a top to bottom rebuild of the organization, they need to maximize their young talent to become competitive again. Players drafted out of power conferences such as the SEC and ACC are accustomed to a full slate of data. Getting to the professional ranks and being less informed than they were in college is far from ideal for player development.

Young hurlers like Reid Detmers, Walbert Urena, and Grayson Rodriguez are likely going to benefit the most from access to pitch tracking and biomechanical data. The development of Rodriguez in particular has huge ramifications for the Angels rebuild. As are the stakes for developing George Klassen, Tyler Bremner, and other talented arms the system.

And it is tantilizing to dream on any possible improvement to Ben Joyce's already incredible arsenal.

But the data revolution will not stop on the pitching mound. If Mozeliak had a trusted source to take over the offensive side of the Angels that change is likely made by now as well. In time, coaches that integrate analytics will be installed at every level of the organization. If Mozeliak has his way, the Angels will be structured like the Cardinals; a modern day mix of scouting, data, and player development adding up to continued success.
