After Friday's 7-4 win in the series opener against the Sox, Maddon accused the Boston coaching staff of ordering reliever Franklin Morales to plunk Luke Scott, which led to a heated exchange between both clubs.
"By the way their players reacted to the entire situation, I knew it did not come from them," Maddon said Friday. "It's kind of incompetent behavior."
On Saturday, Valentine fired back.
"Wow, is that how they do it there," said Valentine, who is in his first year as Boston's manager. "When they throw at our guys, it comes from the coaches, you mean? Oh. I don't know. I don't know how things are done on their side and I don't think they know how things are done on our side. Whatever."
Maddon was aware of the comments when he met with the media prior to Saturday's game at Fenway Park, but he chose not to react to Valentine's statements.
"I think if you just rewind the tape everything is pretty much self explanatory," he said.
Instead, Maddon believed his reaction on Friday night prompted Valentine's response.
"I guess I did the same thing yesterday," Maddon said, "so I'm sure that what I said specifically may have motivated the return salvo."
Maddon doesn't plan on discussing the matter personally with Valentine and would prefer the players to smooth things out between the two teams.
"I'm sure players from both sides have all ready spoken to each other and know exactly what went on last night," he said. "I know the Red Sox players have a lot of respect for our guys and vice versa."
So will there be any carryover on Saturday night?
"No, I really don't [anticipate that]. We're here to play baseball. We don't come to instigate fights," Maddon said.
As for Saturday's game, Scott was back in the lineup after being hit in his right knee by a 97 mph-fastball in his last at-bat Friday. He received treatment on Saturday, heavily wrapped the knee and rode a stationary bike in the Rays' clubhouse before Maddon made the decision to start Scott as the designated hitter.
"I just wanted to make sure Luke's knee was OK, and he's fine to go," Maddon said.
Scott has good career numbers against Red Sox starter Josh Beckett, going 10-for-24 with three home runs and seven RBIs entering Saturday's game.
