That was a painful way to end the eight game win streak.
The Sox had a three run lead entering the eighth inning thanks to a two-run shot by Hanley Ramirez, and a one-run homer by Andrew Benintendi.

The eighth inning started with Addison Reed pitching. He first hit a batter in the foot, allowed a two-run homer, gave up a single, wild pitch, and a walk.
With no outs and runners at first and second, Joe Kelly gave up two consecutive RBI-singles. He struck out the next batter, but proceeded to give up another single, then a sacrafice fly and a walk.

There was a golden opportunity to reclaim the lead in the ninth inning, but fell short by a run. Aroldis Chapman loaded the bases with no outs, all walks.
Benintendi had the chance to make a major difference, but instead he launched a sacrafice fly to left. The ball ended up a double play as Edurado Nunez got called out at third.
With that, there were two outs and Mitch Moreland at bat. He flied out to center to end the game on two pitches.

On the bright side, Edurado Rodriguez looked comfortable pitching again. He tossed six innings with only two hits and two walks against him. He punched out six batters.
With that stellar performance, his ERA has dropped to 3.80 from 4.08.
