PEORIA, Ariz. -- Mariners left-hander James Paxton continued his strong spring with four solid innings of one-run ball, but top White Sox pitching prospect Lucas Giolito had worse luck, as Seattle earned a 7-6 win on Tuesday at Peoria Sports Complex.
Giolito, the No. 11 prospect in the Majors per MLBPipeline.com, had allowed just two runs over nine innings in his first three spring starts. But the 22-year-old right-hander lasted only two-thirds of an inning, while giving up four runs on four hits and a pair of walks in a rough, 30-pitch outing.
"It's hard to pinpoint one issue," Giolito said. "I didn't really execute anything I was trying to do today. 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."

Paxton breezed through his longest stint of the spring, with only a solo homer by second baseman Yolmer Sanchez in the third marring his 62-pitch outing.
"I didn't feel great out there and didn't have my best stuff," Paxton said. "But I mixed speeds a little, kept them off balance. It's going to happen during the season. There'll be days I don't have my good curveball or cutter and just have to figure it out. It's the learning process, and I feel like I've learned a lot about myself."
Mariners second baseman Tyler Smith -- taking advantage of the continued absence of middle infielders Robinson Cano and Jean Segura to the World Baseball Classic -- went 2-for-3 with a home run, double and four RBIs.

Mariners right fielder Mitch Haniger continued his hot spring with a single, double, triple and stolen base in four at-bats, as he raised his Cactus League average to .444.
Left-hander Matt Purke racked up four strikeouts in two scoreless innings of relief for the White Sox, while Everth Cabrera ripped a two-run homer off Seattle reliever Nick Vincent in the sixth.
