Josh Hamilton and Vladimir Guerrero drilled back-to-back home runs in the eighth inning to lift the Texas Rangers to a wild 13-12 victory over the Kansas City Royals in Thursday’s opener of a four-game series.

The Royals grabbed a one-run lead in the top of the eighth on Kila Ka’aihue’s pinch-hit single before the pair of Texas sluggers took Royals closer Joakim Soria (0-1) deep.

Frank Francisco (4-3) picked up the win despite surrendering the lead before Neftali Feliz struck out two in a perfect ninth for his seventh save.

The Rangers jumped out to an 8-0 lead after a six-run second inning, highlighted by a three-run home run from Justin Smoak.

Kansas City scored two runs apiece in the fourth and fifth innings to pull within 8-4, but the Rangers responded with a single run in the fifth.

The Royals later rallied for five runs in the sixth off Texas reliever Dustin Nippert to tie things at 9-9 on RBI hits from Jason Kendall and Mitch Maier and Scott Podsednik’s three-run homer.

Guerrero launched his first homer of the game, a two-run shot in the sixth, before the Royals answered in the seventh when Alberto Callaspo roped a two-run shot to again even the score.
