Seattle Mariners starter Felix Hernandez is expected to miss 4 to 6 weeks after being diagnosed with a grade 1 lat strain in his right side. Seattle manager Scott Servais said that an MRI revealed the extent of the injury.

The Mariners scored twice in the bottom of the 10th inning to defeat Oakland 6-5 Monday, snapping a four-game losing streak.

The Mariners’ disastrous trip concluded with an 11-2 loss and three-game sweep to the Red Sox.

J.P. Crawford and Shed Long, the Mariners’ double-play combination of the future, were both recalled from Triple-A Tacoma on Friday.

For about two innings, victory seemed possible, if not plausible. The Mariners delivered a four-run punch to Boston starter Rick Porcello in the top of the first and figured to get more over the next eight innings, while Seattle starter Felix Hernandez put up an easy 1-2-3 first inning and worked his way out of what could have been a calamitous second inning.

Mitch Moreland hit a three-run home run, Rafael Devers and Andrew Benintendi each added a solo homer, and the Boston Red Sox moved above .500 for the first time this season with a 14-1 victory over the Seattle Mariners.

The moves were announced in advance of the Mariners opening a three-game series with the Red Sox.

J.A. Happ and four relievers combined on a two-hitter, Cameron Maybin contributed with his bat and glove, and the New York Yankees beat the Seattle Mariners 3-1. The Yankees won for the fourth time in five games and headed to Tampa Bay to play the AL East-leading Rays for the first time this year.

Left-hander J.A. Happ allowed one hit in five scoreless innings and Cameron Maybin drove in a run with a second-inning double as the New York Yankees defeated visiting Seattle 3-1 Thursday night.

Whatever was smeared under the hat of Seattle pitcher Yusei Kikuchi, it hasn’t turned into a sticky situation for the Mariners, New York Yankees or Major League Baseball. A day after a dark substance was spotted under the bill of Kikuchi’s cap in a win at Yankee Stadium – possibly illegal pine tar – all sides kept cool. MLB issued no penalty or even a statement on the matter. Yankees manager Aaron Boone said his team would handle things behind the scenes.

On the one-year anniversary of the Mariners’ most recent no-hitter, thrown by James Paxton in Toronto, another left-handed Seattle starter flirted with such a magical possibility.
