Through four games of the season, Red Sox pitchers are enduring one of the worst starts for a staff in recent memory.

"I didn't rethink about it last year, you saw what happened. It was the same plan," manager Alex Cora said after Sunday's 10-8 road loss to the Mariners, Boston's third defeat in four games to open the season. "Whoever's doubting us [after] what we did last year. I mean this year? Check what happened last year."

Just five months after winning the World Series, the Red Sox lost three of four to the Mariners from Thursday through Sunday while allowing 34 runs -- tied for the most of any team in the first four games over the past 10 years.
