The incident happened in the eighth inning of Sunday's loss to the Red Sox.
On Friday night at Camden Yards, Machado made a late slide that injured the left knee and ankle of Boston second baseman Dustin Pedroia, who is still out of the lineup after missing two games in Baltimore.
In other roster news, relief pitcher Matt Barnes will start serving his four-game suspension on Wednesday after dropping his appeal. He will be able to pitch during the process.
The Red Sox and Orioles play again May 1 at Fenway Park.
If Machado had a baseball-sized red mark on his hip or some sore ribs, I would still think throwing at a batter is stupid, but I wouldn't be as alarmed.
"I would never intentionally throw at someone's head", Barnes explained, per ESPN.com. Jab and Zach weigh in on the slide and whether it was dirty and talk about Pedroia's comments about how he had nothing to do with the retaliation.
Machado and Orioles manager Buck Showalter said they weren't going to ascribe motive to the pitch.
Twins manager Paul Molitor said the team thinks it has a "fairly legitimate case" as to why Major League Baseball should at least consider reducing the penalty against Sano. On Tuesday, Pedroia was asked if he created any tension. "I'm not trying to give you a short answer but we're moving on". He also was critical of the high and inside pitches thrown by his teammate.
While most of New England was tuned into the Bruins and Celtics playoff games yesterday, the issues between division rivals Boston and Baltimore continued into the last game of their three-game series. The Red Sox went on to win the game, 6-2, but Machado banked a nice pile of respect for how he handled his would-have-been beheading.
