Jose Lopez continued his spring power surge with a 10th-inning solo homer as the Yomiuri Giants spoiled the Yokohama BayStars' home opener on Tuesday with a 2-1, 10-inning victory at Yokohama Stadium.

The homer was Lopez's third of the new season and gave him 11 RBIs in four games. With two outs and a 3-2 count against BayStars reliever Shuichiro Osada (0-1), Lopez blasted the tie-breaking shot into the left-field stands and just fair.

"I tried to have a big swing with two outs in extra innings," Lopez, a former regular with the Seattle Mariners. "I tried to hit a home run in my at-bat before, too. Before I get to home plate, I think to hit a home run, but once I get to the plate, I try to get a good swing.
