As a musician on the side, Diamondbacks relief pitcher Brandon Medders knows how important it is to be in tune and on time. After a slow start to the season, brought about by a nagging muscle strain in his upper right back at the beginning of spring training, Medders has found his groove.
The singer-guitarist has allowed just one run over his past 12 appearances for a 0.63 ERA and is resembling the pitcher that had a 1.33 ERA over his final 23 outings with Arizona in 2006, when he held opponents to a .178 average and struck out 31 in 27 innings.
Medders had been pitching in middle relief, usually throwing an inning before manager Bob Melvin turned to Brandon Lyon and Luis Vizcaino for set-up duty ahead of closer Jose Valverde. But Medders, who was to challenge for that role before he hurt himself the day before spring workouts began in Tucson, could be on the verge of owning a new gig.
Manager Bob Melvin wasn't ready to make it official, but he's been waiting for Medders to strut this kind of stuff and has been impressed with what he's seen.
"It looks like his confidence is back," Melvin said. "We feel like his stuff is crisper. He's throwing the ball where he wants to. He's using all his pitches. He's to the point where he's in that group where we'd consider him in either a tied or plus game."
Melvin conceded that he probably leaned on Vizcaino a little too much and with Medders' progression, this has been a good time to give Vizcaino a bit of a rest.
REPLAY: By winning the first two games of their series with the Pirates, which included Tuesday night's 7-3 win, the Diamondbacks have captured six consecutive series at home and will look for their first series sweep this season at Chase Field.

QUOTE TO NOTE: "I'm trying. Believe me, I'm trying to bring it down. Sometimes, maybe it works, but it's really just one speed. That's the toughest thing for me, trying to figure out that level. As I've been around the game and played a little bit more, hopefully, I can figure out a nice medium." -- Center fielder Eric Byrnes on playing with one speed: wound-up, excitable fast.
