HR from Iannetta powers Mariners past Yanks

On a night where getting on base came pretty easy for both teams, only the Mariners could take advantage of it Friday.

Working off the strength of three RBIs from Chris Iannetta -- including a go-ahead home run in the fifth -- the Mariners snagged the opener of this weekend's three-game tilt versus the Yankees, 7-1. Right-hander Nathan Karns earned his first win for the Mariners, striking out seven in five innings. He walked four and allowed five hits in the outing. The only run Karns allowed was a home run to Brett Gardner in the first.

The Yankees' bats were anemic during scoring opportunities on the night, leaving 12 on base and notching an 0-for-12 mark with runners in scoring position. Right-hander Luis Severinodidn't have his best stuff, allowing four runs and eight hits while striking out only two over 5 2/3 innings.

Players and coaches from both teams -- and throughout Major League Baseball -- wore No. 42 on Friday to celebrate Jackie Robinson Day.

MOMENTS THAT MATTERED
Road warrior: Iannetta delivered a two-run homer in the fifth off Severino on a well-struck line drive over the left-field fence, projected at 408 feet by Statcast™. Iannetta's second homer of the year gave Seattle a 3-1 lead and was Seattle's 15th long ball in the first 10 games. Iannetta added an RBI single in the eighth and went 3-for-3 with a walk, raising his on-base percentage in four road games to .909 (6-for-7 with three walks), compared to his .111 batting average and .200 OBP in five games at Safeco.

Stranding, not landing: The fourth inning couldn't have started much better for the Yankees. With the game tied at 1, Dustin Ackley led off with a walk. Starlin Castro singled, moving Ackley to third. A Karns wild pitch moved Castro to second. But Karns worked his way out of trouble, striking out Didi Gregorius, Chase Headley and Jacoby Ellsbury in succession, with Headley and Ellsbury going down looking.
