Example for 'pay-to-pubkey-hash' is quoted in Wiki bitcoin script. I have a doubt that 14 is for bytes to push. But the data to push is 20 bytes. Please anyone could explain to me?

Script:

76 --> OP_DUP
A9 --> OP_HASH160
14 --> Bytes to push

89 AB CD EF AB BA AB BA AB BA AB BA AB BA AB BA AB BA AB BA --> Data to push

88 --> OP_EQUALVERIFY
AC --> OP_CHECKSIG
