Needless to say, a batter doesn't want to get into an 0-2 hole.
Batters this season are hitting .152 on 0-2 pitches.
Frame of reference?
On 2-0 counts, batters are hitting .334.
On 3-1 counts, they are hitting .348.
Even on 1-2 counts, batters are hitting .167.
So when a batter gets a hit on 0-2 the effect is more than just the hit itself, but the impact of the letdown on the defensive squad when that batter comes through or, if you see the glass half-empty, the pitcher simply not putting the batter away.
0-2 hitters this season
So far this season, no batter has had more 0-2 plate appearances than Starling Marte with 55. Marte has gone 11-for-51 (.216) with three doubles and 19 whiffs.
Next, in terms of PA is Mark Trumbo going 8-for-52 (.154) with three doubles, a homer and 31 Ks.
Now I want you to pause a moment and think, of all the players in the majors who would most want to have with an 0-2 count at the plate to do damage to the opponent.
Don't immediately say Miguel Cabrera, he's a .125 hitter and he has no homers.
Don't shout Mike Trout either, he's a .200 hitter without a homer.
There is one guy, who consistently manages to find a way to damage his opponents, no matter what the count, no matter what the situation, no matter what the score:
Dustin Pedroia is a .360 hitter on 0-2 counts.
Pedey in 50 at bats has 18 hits, the most in the majors. Alexei Ramirez is next with 13 hits.
What's more, Pedroia has only struck out nine times on 0-2 pitches.
There are other good ones out there
But give me Dustin Pedroia's 18-for-50, .360 batting average and .333 with runners in scoring position with an 0-2 count.
