MESA, Ariz. -- Mike Zunino slugged his third home run of the spring and Boog Powell logged a tying RBI single in a four-run ninth inning that sent the Mariners to an 8-6 win over the Cubs on Thursday at Sloan Park.
Anthony Rizzo launched his first home run of the spring -- a solo shot in the first inning -- and he added a double in the sixth in going 2-for-3 for the Cubs.
Mariners left-hander James Paxton turned in a sharp three-inning outing as he struck out five with no walks in his first spring start after pitching two innings out of the bullpen in his debut last week.

"They have a really good team over there, a strong lineup, World Series champs," Paxton said. "They bring it. It was good to go out there and face a team that talented and have some success."
Zunino added an RBI double on a ball lost in the sun by left fielder Kyle Schwarber in the fifth. Right fielder Mitch Haniger went 2-for-4 with a double and third baseman Taylor Motter had two hits and a walk.
Mike Montgomery, competing for the No. 5 spot in the Cubs' rotation, allowed one run on three hits, including Zunino's solo homer to left in the second. Montgomery, acquired from the Mariners last July, had no walks and one strikeout in his third start of the spring.
"My arm feels great," Montgomery said. "I'm just building my strength. It was a step in the right direction."
The Cubs scored a pair of runs in the fifth on back-to-back doubles by Willson Contreras and Taylor Davis and an RBI single by Jonathan Jay, and Davis tied it in the seventh with a run-scoring single. Jacob Hannemann then drove in the go-ahead run on a single off of Jean Machi in the eighth.
