I don't think there's any kind of 'gentlemen's agreement' against that type of play. To me it's more that baseball has, over the years, slowly morphed from a game where the ball was always assumed to be in play unless specifically stated otherwise to one where just the opposite is now considered to be the norm. -- Think back to Muffy's "steal" of 3rd base on a walk in that series against the Dodgers. Once 'Ball 4' was called, 3B-man Justin Turner, who was in short RF as part of a shift, just started casually strolling, head down the entire way, back towards the general direction of his regular position -- remember also that this was during a freakin' playoff game - as if he had all the time in the world to get there because, well because of course he did, the last play was over and now nothing would or could! happen until the next pitch was thrown. Now I'm not implying that Turner actually thought those specific thoughts but he certainly acted as if the game was in a holding pattern and would be until his pitcher opted to dictate otherwise. Murph meanwhile, alertly saw what was happening and, for maybe the one and only time in his life, made a clever base-running move. Gary, you may recall, once described Murph as running as if under the impression he was invisible. -- That very same week over in the AL playoffs [TEX v TOR], Ranger 2Bman Rougned Odor scampered home when Russell Martin's return throw to the mound dinged off Shin-Soo Choo's bat and into foul territory. Yet, even as he was streaking home, the HP ump was waiving off the play as if not only is the time between batters automatically deemed to be dead-time but now nothing is allowed to occur even in the time between pitches! The umps got together and, after much discussion, eventually allowed the run to count. But it's telling that, even from the arbiters of the game, the very first reaction was that Odor could NOT advance because the game was on pause. Choo, btw, had his back to Martin the entire time so there was no implication that he intentionally interrupted the throw and Odor, to his credit, kept running despite the HP ump's initial call otherwise the whole thing could have really turned into a mess. Now this particular play last night was a bit different. Sanchez actually looked towards Berti at 3rd but then made a lazy throw as if his glance alone was sufficient to negate any hi-jinx -- a habit born of the above mindset most likely -- and then Familia made an awful return throw. Good for Berti, bad on Mets. My overall point here is that I don't think players are reluctant to try oddball tricks like these because they don't want to upset the other side but rather because it rarely occurs to them to do so. If quizzed on it most would probably come to the conclusion plays like these are in fact allowed but that certainly wouldn't be their first thought and some of them would probably have to stew on it a bit and maybe check with one or more of their coaches before coming up with an answer. Now in addition to how more mundane this attitude makes the game of baseball think about the message it sends to fans; if time between batters and even between pitches is dead time where nothing CAN happen, well then that's just another excuse to use that thumb to switch to, and maybe not back from, something else on their TV/Phone/Game console. And you tell me that TV ratings are down? ... huh!
