Lefty reliever feels 'pretty good' facing hitters; righty throws batting practice

Lopez makes spring debut; Romo not far behind

PEORIA, Ariz. -- Tuesday was a promising day for the Giants bullpen, as two of their top relievers, Javier Lopez and Sergio Romo, shook off their respective injuries to make significant appearances on the mound.

Lopez, who has been bothered by biceps tendinitis, worked two-thirds of an inning and threw 18 pitches in his Cactus League debut. He issued one walk and surrendered a hit to Matt Kemp, the final batter he faced.

Asked about his physical condition, Lopez said, "We'll see how it feels tomorrow, but right now it's pretty good."

Significantly, Lopez retired both left-handed batters he faced, Cory Spangenberg and Will Venable. Lopez has established himself as one of the Major Leagues' top lefty specialists.

"It was nice to get out there and work through my mechanics a little bit," Lopez said.

At Scottsdale Stadium, Romo faced hitters for the first time this spring as the right-hander threw live batting practice to Brandon Belt and Brandon Hicks. A sore throwing shoulder had delayed Romo's progress.

Manager Bruce Bochy was at Peoria for the club's exhibition game and didn't see Romo throw. But Bochy guessed that if Romo feels fine Wednesday, his next appearance should come in a Cactus League exhibition.

Guillermo Quiroz, who caught Romo, delivered a glowing report.

"His arm strength is back," Quiroz said. "To me, he looked effortless. I think he's pretty close [to resume pitching competitively]."
