Fielder was on deck at the time and the first person to reach the two players.
"He's my teammate," Fielder said. "I'm out there, what am I supposed to do? I was just trying to make sure I was part of the conversation."
Conger wasn't happy that Odor was taking too long to get in the batter's box to start the inning. The situation became inflamed when Conger came out of his crouch to continue the conversation.
"Rougie is better than me," Fielder said. "If I was a rookie, that wouldn't happen. If somebody got in my face, we wouldn't have had a conversation. If somebody gets in your face, you have to defend yourself."
Fielder said it's up to the umpire to get the hitter into the box, not the catcher.
"I don't know who made [Conger the] on-field policeman," Fielder said. "If that is a big deal, let the umpire handle it."
• The Rangers optioned pitcher Anthony Ranaudo to Triple-A Round Rock on Monday to make room for Nick Martinez, who started in Colorado.
• With Fielder playing first base on Monday, the Rangers had to sit Mitch Moreland. Manager Jeff Banister said there were no discussions on using Moreland in the outfield while the Rangers are in Colorado, because of Moreland's history of leg injuries.
• The Rangers struck out 14 times without drawing a walk on Sunday. The last time that happened was on Sept. 28, 2008, against the Angels.
