PHOENIX -- A day after Stephen Drew's trade to Oakland late Monday, the D-backs filled his roster spot by recalling right-handed pitcher Sam Demel from Triple-A Reno on Tuesday.
Demel was 1-4 with a 4.60 ERA in 51 relief appearances with the Aces in 2012. More recently, the 26-year-old posted a 2.79 ERA with 14 strikeouts in August.
"I've just been attacking hitters more," Demel said. "My changeup has been really good all year, so learning when to use that in certain situations was huge. I've been getting swings and misses with it. It's been good."
It's unclear how long Demel will stay with the big league club, however. The D-backs will promote top prospect Tyler Skaggs on Wednesday to start the first game of their day-night doubleheader against the Marlins, and they'll need to make a corresponding move then.
Regardless of the duration of his stint with the D-backs, Demel is just happy to be back in The Show.
"It feels good, to battle as much I did this year, to try to figure stuff out, and now I've been on a couple really good stretches," Demel said. "It's nice to be rewarded for it. It's a good feeling."
The righty held a 4.21 ERA in 34 games with the D-backs in 2011, and is 4-3 with a 4.88 ERA in 71 career games over two seasons with Arizona.
"When he left here, it was all cutter, but you have to use all your pitches," D-backs manager Kirk Gibson said. "He started off kind of rough down there, but he's thrown the ball pretty good lately."
