If there was any question the feud between the Red Sox and Orioles third baseman Manny Machado would continue, it was answered Tuesday night. Machado was thrown at by Chris Sale and later went on a profanity-laden tirade against the Red Sox organization.

The Red Sox and Orioles have already played seven times this season -- the O's have won four of those seven games -- and they still have 12 more head-to-head games remaining, including two more Wednesday and Thursday nights. Something tells me this Machado-Red Sox feud is far from over.

Here is a chronological recap of how things got to where they are now.

April 21: Machado spikes Pedroia

This all started in the eight inning on April 21. Machado slid into second base on a force play and he spiked Dustin Pedroia in the left calf. Here's the video:

To me, that looks unintentional. It looks like Machado's foot hit the bag and popped up, and Pedroia's calf happened to be right there. Had it been intentional, Machado could have done a lot more damage. Between that and his immediate concern for Pedroia's well being, my gut says it was an unintentional and unfortunate play.

After the game Pedroia said he wasn't mad at Machado -- Machado texted him an apology after the game -- and bragged that he's "turned the best double play in the Major Leagues for 11 years ... The (takeout slide) rule's irrelevant. The rule's for people with bad footwork."

Red Sox manager John Farrell, however, called it an "extremely late slide" and was not happy with the play.

April 23: Barnes throw at Machado

It wasn't until two days later than the Red Sox retaliated against Machado. Red Sox starter Eduardo Rodriguez threw inside a number of times early in the game, then, in the eighth inning, Matt Barnes threw a pitch behind Machado's head and was immediately ejected.

Interestingly enough, Pedroia yelled across the field to Machado to tell him he didn't ask anyone to throw at him. "I just told him I didn't have anything to do with that. That's not how you do that, man. I'm sorry to him and his team. If you're going to protect guys, you do it right away," said Pedroia after the game. 

Here's more from Pedroia, via Jen McCaffrey of MassLive.com:

"It's definitely a mishandled situation," Pedroia said. "There was zero intention of (Machado) trying to hurt me. He just made a bad slide. He did hurt me. It's baseball, man. I'm not mad at him. I love Manny Machado. I love playing against him. I love watching him. If I slid into third base and got Manny's knee, I know I'm going to get drilled. That's baseball. I get drilled, and I go to first base. That's it."

Barnes, naturally, denied throwing at Machado intentionally. He and Farrell both claimed it was a fastball that got away from him, which is the usual defense when a pitcher throws at a hitter intentionally and doesn't want to own up to it. I don't think Barnes was aiming for Machado's head.  My guess is he wanted to put one in Machado's ribs and missed. Barnes is not exactly known for his control, after all. (He's walked 11.2 percent of the batters he's faced since Opening Day 2015.)

Barnes told McCaffrey he was "trying to go up and in, trying to get some weak contact," yet catcher Christian Vazquez was set up outside, undermining Barnes' alibi:

Barnes was fined an undisclosed amount and suspended four games for "intentionally throwing a pitch in the area of the head." He initially appealed the suspension, though he dropped the appeal shortly thereafter and served the ban last week.

Pedroia, it should be noted, missed three games after getting spiked in the calf. He has since returned to the lineup.

May 1: First game since Barnes throws at Machado

Barnes threw at Machado in the final game of a three-game series at Camden Yards. On May 1, the two clubs opened a four-game set at Fenway Park. There were no real fireworks in the first game of the new series. Mookie Betts was hit by a pitch from Dylan Bundy, which may or may not have been intentional:

Betts took his base and that was that. No one else was thrown at or hit in the game -- the Red Sox did pitch Machado inside a bunch, though that's not uncommon, he's a great hitter and teams try to bust him inside -- or anything like that.

Machado did hit a home run, however. Hit a home run and he admired the heck out of it:

That is a man who very much enjoyed hitting a home run against a team that had thrown behind his head the last time they met.

So far this season Machado is 7 for 28 (.250) with two doubles, three home runs, and six runs driven in against the Red Sox. That covers seven games.

May 2: Sale throws at Machado, Machado goes on rant

Tuesday night, in the second game of this four-game series, Sale rekindled this feud by throwing behind Machado's legs in the first inning. There were no warnings issued prior to the series despite the bad blood, so Sale was not ejected despite the obvious intent. Both clubs were issued warnings instead.

Here is the pitch behind Machado's legs. Sale would later strike him out to end the inning.

Later in the game Machado exacted some level of revenge by hitting a home run over the Green Monster against Sale. The BoSox had the lead at the time and would go on to win the game, however.

Following the game Machado ripped both Sale and the Red Sox, saying he's lost all respect for the organization during an expletive-laden tirade. Here's a transcript of his rant, via Jon Meoli of the Baltimore Sun:

"I mean, if you're going to [expletive] hit me, hit me," Machado said. "Go ahead. [Expletive] hit me. Don't let this [expletive] keep lingering, [expletive] around, and keep trying to hit people. It's [expletive] [expletive]. It's [expletive] [expletive]. MLB should do something about it. You have pitchers out there with [expletive] balls in their hands throwing 100 miles per hour trying to hit people. I've got a [expletive] bat, too. I could go up there and crush somebody if I wanted to. But you know what, I'll get suspended for a year, and the pitchers only get suspended for two games. That's not cool."

...

"Coward stuff," Machado said. "I mean, that's stuff that you don't [expletive] do. But I mean, I'm not on that side. I'm not in that organization. They're still thinking about that same slide that I did. There was no intention on hurting anybody and I'm still paying, I'm still trying to get hit at. Get thrown at on my [expletive] head. They're [expletive] throwing everywhere. [Expletive] [expletive]. I've lost my respect for that organization, that coaching staff and everyone over there."

Sale, for what it's worth, didn't care too much about what Machado said. He said he's "not losing sleep" over the incident or the ongoing feud between the Red Sox and Machado.

Given the fact the Red Sox have thrown behind Machado twice, including once behind his head, MLB and the umpiring crew figure to be on high alert going forward. Anything closely resembling a pitch at or behind a hitter will likely be met with an immediate ejection plus a suspension.

With 12 game still on the schedule between these two AL East rivals, I get the feeling his Machado-Red Sox feud is not over yet. Hopefully no one gets seriously hurt along the way.
