PEORIA, Ariz. -- During his first three Cactus League starts, White Sox right-hander Lucas Giolito lived up to his billing as the Majors' No. 11 prospect per MLBPipeline.com. He allowed two runs on seven hits and two walks, while striking out six over nine innings.
In Tuesday's 7-6 loss to the Mariners, Giolito looked like a work in progress.
"I take what I can learn from it," Giolito said. "It starts with the first batter. You want to put that guy away 0-2, you want to execute your pitch. I try to throw a fastball, and threw it right down the middle. And from there, just not feeling my pitches, throwing a lot of stuff in the dirt. It's one of those days when you go out there and you don't compete to the best of your ability."
Giolito faced eight batters in two-thirds of an inning, allowing four hits and two walks.

"I didn't really execute anything I was trying to do today," Giolito said. "As a starting pitcher, you want to work efficiently, you want to throw low pitch count innings, work through a game. I threw 30 pitches and didn't get out of the first inning. I just didn't do my job."
Giolito, 22, came to the White Sox along with Reynaldo Lopez and Dane Dunning in a December trade that sent Adam Eaton to the Nationals. He was 0-1 with a 6.75 ERA in six games (four starts) over three stints with the Nationals in 2016. 
"I need to work on pounding the strike zone more consistently," Giolito said. "I can't fall behind most of the batters I'm facing."

Worth noting
• Manager Rick Renteria was pleased with Carson Fulmer's progress over the last year, and his progression through Spring Training. His latest showing was a four-inning outing against the Indians on Monday.
"He's starting to command the zone a little bit better," Renteria said. "He slowed his windup down. He's mixing his pitches well. He's a poised young man. Even last year, he showed a tremendous amount of energy, a lot of fire. We really like him. He's got a good arm."

Nevertheless, Renteria figures Fulmer, the club's No. 5 prospect, probably wouldn't make the Opening Day roster.
"I'm sure that he still has to get some work done," Renteria said. "With the guys that we have in camp, it probably puts him starting off in the Minor Leagues. That's just speculative on my part. We still have three weeks left in the [Cactus League] season."
• Renteria continues to like what he's seeing from 21-year-old infielder Yoan Moncada, the No. 2 prospect in the Majors, during Spring Training.
"He's chipping away, seeing enough pitches, trying to get himself into a rhythm," Renteria said. "We're really working on him expanding his defensive abilities. He's a young man who's just at the beginning end of scratching at the surface of what he can potentially be."
