Before we go any further, let me just answer that question right now: Jalen Beeks.
Yes, you didn't ask a question, but we still had to clear the air there. The question you didn't ask was: who is the guy on the PawSox worth watching out for? There, that's your answer. Here's why:
Beeks was the Red Sox Minor League Pitcher of the Year last year and now he's doing even better. Through eight starts with the PawSox this season, he is 2-2 with a 2.28 ERA in eight starts. He has struck out 65 batters in 43.1 innings and walked just 10 batters. He has not walked more than two batters in any given outing as well.
Beeks is 24 years old and was the team's 12th round draft pick back in 2014. The lefty has steadily climbed up the ranks of the Red Sox system and is now just one rung below the big league level. So yeah, this is someone to keep a close eye on.
At the moment, Beeks is really the team's prize possession in Triple-A. That doesn't do a whole heck of a lot for the big league club though since they have a bucket load of starters: Chris Sale, David Price, Rick Porcello, Eduardo Rodriguez, Drew Pomeranz, Steven Wright, Hector Velazquez and Brian Johnson. That's eight guys right there.
It's really hard to say if he's gonna do anything for the big league club this season but hey, a lefty who can get guys to swing-and-miss is always a good thing.
Speaking of lefties, Robby Scott has a 1.84 ERA down there in 16 outings this year with three walks and 24 strikeouts in 14.2 innings.
That said, there is some lefty depth in the Red Sox organization, for what it's worth. This, plus a healthy Austin Maddox and Tyler Thornburg should certainly help the organization when needed (plus Brandon Workman).
