What is a number like that based upon? Joe had 22 GIDP in 666 plate appearances this past season. Trevor led the league with 28, in 632. Obviously that's not close to 25%, so we must be talking about fewer PA. Focusing for simplicity on the greater DP threat, Trevor, I see on his b-r.com splits page that he had 48 PA all season where it was one out and only a man on first. 13 GIDP came from that, which is a 27% rate. Inning over, a very bad outcome, for those times. A strikeout (he also did those sometimes ) is bad too, but not as bad. There were also (if I added in my head correctly) 78 other PA with any combination of a man on first (and/or other bases) with fewer than 2 outs, from which came the other 15 DP. That's under 20%. A strikeout is bad too, but not as bad. And then there are the other 506 times Trevor came to bat, when a DP was a very remote possibility if at all. (Indeed none of his DP that season came when no one was on first.) That's 0%. A strikeout is worse in all those situations, by not even putting the ball in play for a chance involving your BABIP, nor adding a baserunner via a walk. If choosing a pinch hitter, sure, one would factor these chances in with the particular situation. For the starting lineup, hopefully what we're mostly talking about here, one is kind of stuck with the situational luck of the draw through the course of the game. The DP rips your heart out that inning. Strikeouts are death by a thousand (OK, one or two hundred) cuts, representing missed opportunity. Over the long season, I don't see the DP as markedly more deadly.
