BOSTON - The Red Sox showed the type of fight on Sunday that wasn't seen much at all earlier this season, but one too many extra innings did them in.
They turned a seven-run deficit in the 3rd inning into a tie game in the 9th, but lost to the Mariners in 12 innings, 10-8.
Sox relievers held the Mariners scoreless from the 8th inning to the 11th inning, but Craig Breslow - coming out to pitch his third inning of the game - allowed the game's winning run, and Robbie Ross Jr. came on with the bases loaded to allow another.
The Seattle Mariners jumped all over Red Sox rookie Henry Owens early on, as Owens allowed back-to-back home runs to Robinson Cano and Franklin Gutierrez in the 1st inning and another one to Gutierrez in the 3rd inning.
The third home run put the M's up 7-0, but the Sox would chip away.
Down 8-6 in the 9th, the Sox scored one and loaded the bases for Travis Shaw with two outs. Shaw ripped a single to left field which easily scored Brock Holt from third base. But David Ortiz, representing the winning run, was sent home on the hit and was nailed at the plate with plenty of time. The Sox came all the way back from down 7-0, but ran into a costly out to send it to extras.
The Sox offense showed up in the 3rd inning when Xander Bogaerts hit a solo home run that cleared the Green Monster. And inning later, Rusney Castillo did the same thing.

A pair of sacrifice flies in the 4th and 5th innings, one by Josh Rutledge and the other by David Ortiz, brought the Red Sox to within three runs, 7-4.
Owens settled down after the third inning and didn't allow a run in the final three innings that he pitched. He finished with a line of 6.0 innings, seven runs, 10 hits, a walk, and 10 strikeouts.
Since 1978, the only other Red Sox pitchers as young as Owens (23 years, 26 days) with 10 or more strikeouts in a game are Jon Lester ('06) and Roger Clemens ('84).
Owens was relieved by Alexi Ogando in the 7th, who proceeded to allow a solo home run to Nelson Cruz. Ogando has now allowed seven home runs over his last 14.1 innings.
The Sox responded again in the bottom of the inning, but not with any actual hits. Both Mookie Betts and Brock Holt walked and were successful in a double steal.
Xander Bogaerts then grounded out to first base, scoring Betts. With Ortiz up, reliever Fernando Rodney threw a wild pitch that scored Holt. Ortiz then grounded out to end the inning, but not before the two runs would close the gap to 8-6.
Trailing by the same score in the bottom of the 9th, the Sox put two men on for Bogaerts, who grounded weakly to second base and was thrown out, but drove in a run. That set up Shaw's RBI single to tie things up and send it to extra innings.
