Too soon, of course, to consider it to be a trend, but worth a quick hit in order to put it (so to speak...) "into play"...
There have been 19 starts with 100+ pitches from the starting pitcher over the first five-plus days (we fudge here, since the season had a single opening night game on 4/5...) of the brand-spankin' new season.
This contrasts with 38 such starts over the same time frame in 2014.
You are cautioned not to take this as evidence of increasing caution, but...there it is.
We will follow up...stay tuned.
[UPDATE: As of 4/16, this ratio is remaining pretty much the same as what was initially reported. Now eleven full days into the season, the total number of 100+ pitch count games is at 59, as opposed to 111 such games over the same span in 2014. ]
