The incident came during the Rockies' 12th loss in the last 16 games, which dropped them to 24-30. But Weiss said he has seen and played on teams that won or competed for World Series titles and had blowups. They didn't happen publicly, and some were far more spectacular.
"It doesn't happen often, but it does happen occasionally, probably even moreso when I played," said Weiss, who played on the Athletics' 1989 World Series winner and made plenty of other playoff trips with the A's and Braves. "I remember several times where there would be altercations on the plane or on the bus, and you'd have to get in between guys.
"Our sport is different than any other sport. We play every day. We're together every day. You count Spring Training it's virtually every single day for eight months. Those things happen. Emotions are a big part of being an athlete. Sometimes as a competitive athlete you want your space or there's tension at times. It's not that big a deal."
Weiss said he was unaware Arenado's outburst -- with catcher Nick Hundley, Weiss and third-base coach Stu Cole stepping in front of him -- was on television until after the game. Arenado noted after the game that it would have been better to express himself that way in the tunnel beneath the dugout. Weiss agreed, and noted that he felt Arenado was not trying to embarrass any single person.
"We know Nolan, the people that are around him every day," Weiss said. "He's very intense, wants to win badly. It's not uncommon to see stuff like that.
"I think he felt bad about it. He didn't want to disrespect any one person or a coach, so he made sure after the fact that he cleared the air there. But I don't have an issue with guys showing that type of emotion."
• Lefty Boone Logan (left shoulder inflammation), who hopes to return Monday against the Dodgers, was scheduled to pitch for Triple-A Albuquerque on Saturday during a brief injury rehab assignment.
• Right-hander Christian Bergman (left oblique strain) is at the club's training center in Scottsdale continuing rehab and strengthening. The plan is for him to begin throwing by midweek.
• Shortstop Jose Reyes went 1-for-3, with the hit being a home run, Friday in the second game of his rehab assignment at Albuquerque. Reyes, who was suspended through May 31 because of an offseason domestic violence case and is on the restricted list, is scheduled for a rehab assignment of not more than 14 days.
