CLEVELAND -- For four innings the Cleveland Indians' hitters were quiet. Then they got noisy.
Jason Kipnis' walkoff three-run home run with two outs in the bottom of the 10th inning gave the Indians a 6-3 win over the Seattle Mariners Friday night.
Seattle pitchers had retired 15 batters in a row before Drew Stubbs drew a two-out walk in the bottom of the 10th inning. Stubbs stole second and went to third on an infield single by Michael Bourn.
Kipnis then belted an 0-1 pitch from Lucas Luetge just over the wall in right field for his seventh home run.
Trailing 3-1 after five innings, the Mariners knocked Indians starter Ubaldo Jimenez out of the game in the sixth inning. Justin Smoak led off the inning with a single on Jimenez's 98th and final pitch of the game.
Left-hander Rich Hill relieved Jimenez, and Raul Ibanez hit Hill's second pitch over the right field wall to tie the game at 3-3. It was Ibanez's fourth home run in the last four games and his seventh of the season.
Jimenez, who was not involved in the decision pitched five innings and gave up two runs on seven hits. Jimenez struck out a season-high nine batters and walked one.
Jimenez came into the game having pitched well in recent starts. After going 0-2 with a 10.06 ERA in his first four starts, Jimenez in his three starts prior to Friday was 3-0 with a 1.45 ERA.
Jimenez was dominating in the first two innings, striking out five of the first seven batters he faced.
The Indians took a 2-0 lead in the second inning off Seattle starter Brandon Maurer. Nick Swisher led off the bottom of the second with a walk, and he went to third on a double by Carlos Santana.
Swisher scored on a sacrifice fly by Jason Giambi, and Santana scored on a wild pitch by Maurer.
The Mariners got a run back in the fourth inning on a solo home run by Kendrys Morales, a towering blast into the second deck in right field, a drive estimated at 429 feet.
The Indians countered with an opposite-field home run to right field by Stubbs to push the Cleveland lead to 3-1 in the fifth.
