Timely.
The Sox are 22-20, which is better than I expected. The Sox are 4th in MLB in runs scored--with a "no name" lineup--which is fantastic. But the team ERA is now 27th in MLB, definitely a disappointment.
The 8 game winning streak ended 9 days ago. Since then, just as you say, the rotation seems to have taken a turn for the better.
But the bullpen's wheels have literally come off--signified last night when Reyes took the mound for the 9th inning. Winck got hammered by St Louis. Jansen, our $16M closer, got hammered twice by St Louis. Schreiber hasn't pitched because he's hurt and is probably going on the IL. Brasier is gone. Bleier could be right behind him. Bernardino's ERA for May is 6.14.
Assuming Jansen is actually OK, I see two decent relievers for tonight: Martin and Jansen. My guess is Whitlock and Crawford, both of whom can start, will go to the bullpen in an effort to reconstruct one. So will Houck, with Pivetta getting the 5th starting spot after Sale, Paxton, Bello, and Kluber.
Finally, the "no name" lineup seems to be struggling: 5 runs total in the last 3 games against the Cardinals and Mariners.
To paraphrase Bette Davis in All About Eve, "fasten your seat belts, it's going to be a bumpy season."
