SURPRISE, Ariz. -- Jack Cust launched a solo homer in the 10th inning, his second of the game, capping a wild final three frames in the Mariners' 9-8 victory Saturday over the Rangers at Surprise Stadium.

Trailing by four runs in the eighth, Adam Kennedy hit his second Cactus League homer for the Mariners off Darren O'Day -- a blast that was immediately followed by consecutive solo shots from Mike Wilson and Cust to knot the score at 6.

Omar Quintanilla, a University of Texas product who was signed by the Rangers in the offseason, broke the deadlock with a two-run home run in the bottom of the eighth. The Mariners tied it when Luis Rodriguez scored on a wild pitch and Steven Baron singled home Michael Saunders in the ninth.

With Doug Fister working in a Minor League game, the Mariners went with bullpen candidates throughout the game. Starter Fabio Castro gave up four runs in the second inning.

Adrian Beltre led off with a single for the Rangers, but all four runs scored with two outs on an RBI double by David Murphy, a triple by Matt Treanor, a single by Mitch Moreland and a double by Ian Kinsler.

Mitch Moreland, batting in the No. 9 spot, went 2-for-2 with a pair of singles while Michael Young reached base three consecutive times on two walks and a single. The Rangers' Cactus League losing skid is now at five games.

Mariners shortstop Jack Wilson returned to the lineup after missing two days because of personal issues and went 3-for-3 with an RBI. He has five hits in his past six at-bats and is hitting .500 for the spring.

Franklin Gutierrez returned to the lineup after missing two games with back stiffness, going hitless in three at-bats.

Rangers starter Neftali Feliz went five innings and allowed two runs on four hits, two walks and three strikeouts. He threw 72 pitches, including 42 for strikes, and now has a 1.93 ERA in four outings.

Up next for Mariners: Erik Bedard makes his fourth Cactus League start Sunday as he continues his comeback bid when the Mariners host the Padres in a 1:05 p.m. PT game at Peoria Stadium. Bedard, who hasn't pitched in the regular season in 18 months due to shoulder problems, is 1-0 with a 1.59 ERA in 5 2/3 innings. His last outing was an unofficial Minor League intrasquad game Tuesday, in which he gave up five hits and two runs in 3 1/3 innings.

Top closer candidate Brandon League, who got roughed up Friday, gets a chance to bounce back with an inning of work and Jamey Wright and Josh Lueke are also scheduled to pitch. Fans can listen live on Gameday Audio.

Up next for Rangers: Left-hander Derek Holland pitches for the Rangers against the Royals at 3:05 p.m. CT on Sunday at Surprise. The Royals and Rangers split the first two games they've played at the complex they share. Alexi Ogando, David Bush and Darren Oliver are scheduled to pitch in a Minor League game on the back field.
