Lowe has a 13.50 ERA in 2 2/3 innings of work out of the Rangers' bullpen. He couldn't protect a two-run sixth-inning lead and had command issues in a 3-2 walk-off loss to Detroit on Wednesday.
"If I had the option, if they told you can sit in the big leagues all year and throw 30 games or you can go to Triple-A and throw 60 I would go to Triple-A," Lowe said. "I want to pitch. I don't want to work hard in the offseason to just sit around. I'm never going to complain that my starters are pitching the way they are, that's unheard of. To have an opportunity to pitch everyday that's what I want to do."
The right-handed Lewis, who is scheduled to start Tuesday against the Angels, had been on the paternity leave list to tend to the birth of his second child.
The move leaves lefty Michael Kirkmanwith the Rangers for the time being. Kirkman was called up from Round Rock on Friday morning to take Lewis' place on the roster.
Manager Ron Washington said he's confident Lowe will return to the big leagues at some point.
"It's not what I want him to do, it's what he needs to do, he needs to get some consistent work," Washington said. "He hasn't pitched in a whole year, he certainly can help us at the major league level but he needs to get some consistent work and we haven't been able to get that to him here."
