PHOENIX -- Three Mariners homered off Clayton Kershaw Friday night in a 5-2 win over a split-squad Dodgers club at Camelback Ranch-Glendale.
Tyler O'Neill mashed a two-run homer in the fourth inning, and Leonys Martin (on an 0-2 pitch) and Danny Valencia went deep in the fifth, all off Kershaw, who allowed four runs on six hits in five innings with eight strikeouts and two walks. Kershaw struck out four of the first five batters he faced.
"Not the best outcome tonight, but a good work day and just have to keep going," said Kershaw. "It's always good to be humbled, so this is a good one tonight."
Ariel Miranda started for Seattle and went three innings, allowing a two-run single in the third inning by former Mariner Franklin Gutierrez. He was signed by the Dodgers to hit left-handed pitchers like Miranda, who struck out the side in the second inning.
The Mariners added an unearned insurance run in the seventh inning. They stranded 10 runners and were 1-for-9 with runners in scoring position.
Yasiel Puig had two hits and a stolen base for the Dodgers. O'Neill, Joe DeCarlo and Tyler Smith had two hits each for Seattle.
Dodgers outfielder Andre Ethier (hip stiffness) made his first game appearance since March 6.
