Tagging on a sacrifice fly from third base as a pinch runner, Marisnick bowled over Lucroy as he attempted apply a tag.
The suspension would cost Marisnick roughly $24K of this season's $2.212MM salary (in addition to the fine).
"After thoroughly reviewing the play from all angles, I have concluded that Jake's actions warrant discipline", MLB chief baseball officer Joe Torre said in a statement accompanying the announcement.
If he didn't appeal, then the suspension would have gone into effect Thursday. The Angels catcher sustained a concussion and broken nose.
Marisnick will sit for the first half of the Astros' series with the Rangers this week.
"First and foremost. I hope he's OK", said Marisnick after the game. "That was a bad play".
"I spoke with him after the incident". And I watched the play again and it looks ... he just drops right in front of me and once I kind of made a decision it was too late.
Marisnick later took to social media to explain himself, saying "I thought the play was going to end up on the outside of the plate". Lucroy went down hard and was bleeding from his nose, and had to be carted off the field.
MLB Rule 6.01 (i) concerning home plate collisions states, "A runner attempting to score may not deviate from his direct pathway to the plate in order to initiate contact with the catcher...or otherwise initiate an unavoidable collision".
"Major League Baseball should probably take a look at it and consider some type of suspension, quite frankly", he said.
