A simple piece of chewing gum has turned up the heat twice this season between NL West division rivals.
A look back at how it all went down...
Incident No. 1 -- April 9 in San Diego
Angel Pagan and Padres catcher Derek Norris exchanged words in the top of the ninth inning of a 1-0 Giants win, and afterward Pagan explained that the tiff started after he accidentally threw a piece of gum under Norris' legs. As Pagan told it, he stepped into the batter's box and saw a dirty piece of gum where he would place his foot. He picked it up and tried to throw it aside, but the stickum on his gloves mixed with the gum and it flew directly under Norris, not away from the plate as intended.
"It's nothing to be mad at," Pagan said. "That's his game face, I respect that ... But I didn't do anything wrong."
As Pagan started to tell the story, he warned reporters: "If I tell you, you're going to laugh." He went out of his way to say the incident is "in the past."
"That's not a thing I like to happen," Pagan said. "But that's the nature of the (game). We're playing with so much adrenaline."
That showed on the next pitch when Craig Kimbrel, the new Padres closer threw a fastball up and in. Pagan countered with a triple to deep center and he crouched and screamed as he straddled the bag. He admitted he was angry in the moment.
"I get excited, but I was angry," he said. "I didn't feel I did anything wrong and then I got thrown at right here in my chest."
The Giants got the last laugh, winning in the 12th inning.

"It was a great game overall," Pagan said. "It was a very fun game, interesting, fun. Everything."
Incident No. 2 -- July 21 in San Diego
Hector Sanchez, in his first start since being recalled from Triple-A Sacramento, put Tuesday's game away with a sixth-inning grand slam. Sanchez's first grand slam came last April in Colorado when the Rockies intentionally walked Joaquin Arias to load the bases. This time, Gregor Blanco was intentionally walked so Dale Thayer could go after Sanchez instead.
Sanchez said he didn't take it personally, but he did show a bit of flair as the ball screamed for the right-field seats. Sanchez paused and then flipped his bat, and as he headed toward first, Thayer took the chewing gum out of his mouth and threw it at Sanchez.
"I didn't notice that," Sanchez claimed. "I'm just trying to enjoy the game. It's a grand slam, you don't hit a grand slam every day. I'm just trying to enjoy the game. If somebody gets mad at me, I don't know what the reason is. I just enjoy the game."
The Padres did get mad, and revenge came in the ninth. Kinda. Shawn Kelley threw inside on his first pitch to Sanchez and then followed him to first on a groundout. Kelley said a few words to the young catcher.
"He told me something," Sanchez said. "I (didn't) hear what he told me."
Kelley claimed he was "just trying to pitch my game."
"I guess that's part of the game now," he said of the bat flip. "To me, that's a little disrespectful, especially to Dale. I don't think there's a place in this game for that, but it's part of it. Guys admire what they do, and when you get one, sometimes guys watch it. But that's between him and his teammates and the Giants. That's not our business."
The Padres made it their business and the benches cleared. It was a typical baseball clearing, with players mostly standing around. Only a couple of players had to be held back and the teams never got close to an actual brawl.
The biggest blow might have been landed later, when Angel Pagan, referencing the gum-toss earlier this season that enraged Padres catcher Derek Norris, cut Sanchez's interview off by jokingly saying of Thayer, "He's copying me, man!"
"That's my move," Pagan said.
