All valid points but most probably we will never know since the Home Run is too vital to the game and if pitchers blow out their arms MLB snd owners will just see it as an incentive to not pay high salaries for stating pitchers. If I was an owner I would be very hesitant to pay top dollar over many years for pitching and I think that's beginning to play out and will become the norm soon. Look what the Tigers are doing under Harris. Low one and two year deals, develop a bullpen of "multi inning" relievers, Avoid "Closers" who command big $$, develop your draft picks and work the waiver wire and have bullpen days. Forget about multi year big dollar deals. Arod signed for 4 years 80 million. Harris could have added one year and done that easily but refused, same with Friedman and LA at the trade deadline refusing to add one year to ok the trade. Baltimore which is loaded passed on all the big names and traded for Burnes for one year. Sure there are outliers, Yamamoto and Nola for a couple but one brings huge gate receipts and promotional money to LA and the other is a retuning star. Starting pitchers are targeting 5 innings / twice through the lineup now so why pay huge dollars for that ?
