I don't want to go around automatically handing out free passes to 8th place hitters almost regardless of the count. Hell, it was the 4th inning in a tie game with 2 outs and one runner aboard, hardly a critical situation. Terry used to do that almost as a reflex and what you wind up doing is turning over the lineup more often and assuring that the opposition starts the next inning with the top of the lineup instead of the pitcher, something which likely increases their chances of scoring the next inning at least as much as you might decrease it with the IW - although once you toss in that Corbin was actually out-hitting Murphy going into the game (Corbin = .263 and hit over .300 in 2016) even the best case scenario is hardly a given. More than one runner on? OK. Later in the game? Sure (although then they'd likely PH). Facing a better 8th place hitter? Yeah maybe. But unless the count were already 3-0 (or maybe 3-1) after the SB, I'm not going to want to make a habit of running from the JR Murphys of the world, a guy who essentially is Anthony Recker* w/half the HR rate * Recker, btw, is current hitting quite well for AAA Reno [.327/.431/.673 over 55 ABs] in the Arizona system - so he and Murphy are essentially battling for end of the bench jobs in Phoenix
