TUCSON, Ariz. (AP) _ Jay Buhner hit two home runs, but the Arizona Diamondbacks still went on to defeat the Seattle Mariners 9-8 in 10 innings.

Greg Colbrunn went two-for-three with a home run for Arizona.

The loss capped a long day for the Mariners. Their bus trip from their Peoria training camp, normally a two-hour drive, took five hours because a propane truck crash closed Interstate 10.

Luis Gonzalez hit a three-run homer for Arizona, and Lenny Harris hit a game-tying solo home run in the 10th. The winning run came when Hanley Frias walked, advanced to third on Colbrunn's single, then scored on Luis Ordaz's soft grounder to shortstop Charles Gipson, whose throw to the plate was not in time.

The left-handed Harris, who had one homer all of last season, hit this one with one out off left-hander Arthur Rhodes.

``The one I hit last year was off a lefty last year, anyway,'' Harris said. ``Once you get locked in and you finish good and you're swinging the bat good, pretty much it doesn't matter. You've just got to be patient up there, get a pitch and put good wood on it.''

Colbrunn, who hit a solo homer in the fifth to give the Diamondbacks a 7-4 lead, has three homers and is hitting .556 (10-for-18) in the spring.

Mariners' manager Lou Piniella left the game early with a sore back.

Buhner hit a leadoff homer off Armando Reynoso in the second and a two-run homer off Brian Anderson in the fourth, giving him four home runs in the spring. His homer off Anderson sailed high over the green wall in straightaway center.

``I'm feeling great right now, so ride the wave,'' Buhner said. ``I'm going to be selfish right now. I think I have a lot to prove, not only to the people out there, but to myself, that I'm healthy, that I can get myself ready for the season.''

Seattle's Freddy Garcia allowed five runs on five hits in 2 2-3 innings in his second outing.

Arizona's Byung-Hyun Kim struck out five, including Alex Rodgriguez, in 2 2-3 innings but also allowed three runs.

Seattle tied it at 7-7 with three runs in the eighth, the last two on Brian Hunter's two-out single off Jeremy Ward. The Mariners went ahead 8-7 in the top of the 10th on Hunter's RBI double.
