Showalter said it doesn't bother him when he sees other teams in the American League East active around Friday's non-waiver Trade Deadline.
"We are kicking around a lot of things -- sometimes the best moves you make are the ones you don't make. I could tell you abut three or four we decided not to do in the last two years that if we made them we would have really regretted them," he said. "Of course, I won't tell you about the other ones that we wish we would have made."
The O's have been rumored in a bunch of potential moves lately, with San Diego's Justin Upton among the recent names to surface. Upton would be a rental, and the O's acquired a rental down the stretch last year in lefty reliever Andrew Miller, who signed as a free agent with the Yankees last offseason.
Showalter acknowledged Tuesday it's tough to find an impact player of that quality who fits your needs at the Deadline. It's unknown if the O's, who were well above .500 at this point a year ago, would be willing to give up something to get a player for two months.
"We don't have Eduardo Rodriguez to trade this year," Showalter said of the promising young lefty the O's sent to Boston in exchange for Miller. "Of course I'd do it again.
"The problem is when people are asking for people that are part of what you are trying to do this year. That's tough. And if they go away, then who?"
Showalter is likely referring to young players like Jonathan Schoop and Kevin Gausman, who have drawn a lot of interest from outside clubs, though it's highly unlikely the O's would be inclined to move either. With a thin farm system -- and injuries to top prospects Dylan Bundy and Hunter Harvey -- the club is gauging interest in a number of its current players, including relievers Brian Matusz and Tommy Hunter.
