Manny Machado is a career .209/.259/.423 hitter over 51 career playoff games -- who are some other stars who have been similarly bad in the playoffs?

Its easy to have a few bad series and I don't put much stock in to small sample size. But Manny has played 51 games now in the playoffs which is quite substantial.

To be fair he did have that one big NLCS

For the Orioles in my lifetime the biggest Orioles playoff disappointment was probably Adam Jones hitting .155/.206/207 in his limited playoff action with the Orioles although not really a huge sample size.
