In today's baseball, throwing in the upper 90s is much more commonplace than it was even just a decade ago. Bullpens are stacked with fireballers and starters don't throw nearly as many innings as they used to, so there's no need to hold back on the mound.
Add in better training programs, breakthroughs in surgeries and recovery and new nutrition habits and it's no surprise that pitchers are throwing harder than ever.
