This from Speier's twitter on Groome's pro debut;

Jason Groome: 2IP, 0R, H (2B), 30 pitches, 19 strikes, 7 swing/miss (5 on FB, 2 on CB), 3K.

Michael Chavis got promoted to Salem. Unfortunately it doesn't look performance related as he had been 7 for his last 42 with a 0:17 BB:K ratio. It seems like maybe he got promoted to prevent him from getting too psychologically down and maybe as a precursor to Dalbec getting promoted.

Tyler Hill's been hitting rather well in Lowell (.347/.414/.515 in 52 games). Bobby Dalbec's also hitting .386/.426/.727 in 23 games in Lowell.

Kopech's rocking a 14.2 K/9 in Salem right now. That figure would rank among the best relievers in MLB, never mind starting pitchers. He's struck out 10 or more batters in three consecutive starts and in four of his last five starts. The walk rate is still kinda high (4.2), but he's walked only 9 batters in 29 innings this month (as opposed to 15 in 22.1 innings in July).

Jason Groome being promoted to Lowell. Bradford said he will start either Thursday or Friday in Connecticut.

Kind of surprised Groome got promoted so soon after all of just 4 innings in the GCL. They held to their word when they signed him that he'd be pitching in Lowell after some time down in Florida. The longer it went before he made an appearance had me thinking that promoting him to Lowell would be unlikely but here it is. It's a pretty unusually aggressive move. Sure Logan Allen and Enmanuel DeJesus pitched a few innings in Lowell last year but they had gotten in a lot more appearances in the GCL. High school pitchers almost always spend the entire season down in the GCL after getting drafted or get promoted to a lower level short-season season than the New York Penn League.

Obviously very excited about Kopech. There have been big improvements with his delivery and slider. Kopech and Groome are as talented a pair of pitching prospects as there is in baseball. There are almost zero promising pitching prospects at the Double-A and Triple-A levels but the pitching propects at the lower minors is looking better, even after Kopech and Groome. I really like Raudes and if his velocity takes a leap next season, he'll be extremely intriguing. I really liked the Shawaryn selection too. Josh Pennington has a huge arm and has pitched really well his last three times out at Lowell.

Here comes Moncada.

Victor Diaz has become a very intriguing reliever or re-intriguing reliever if that's allowed in the english language. He came into the season as a member of an ever expanding list of pitchers who've hit 100 mph and since the Red Sox farm system isn't stocked with many hard throwing relievers, that made him very notable. Unfortunately he absolutely bombed early in the year. The opposition would have trouble scoring up to the point he entered and then they'd score like 5 runs in his outings. I thought for sure he'd be demoted to extended spring training and then later show up at Lowell. It wouldn't have been the end of the world because he had been pushed aggressively from the DSL, him being 22 I assume being one of the reasons. Instead he stayed and has pitched so well that he's become Greenville's closer.

More than stats, whether good or bad, I really like how smooth his motion is. On paper, if you see that a pitcher hits 100 mph, is a bit older than usual for his lack of experience and is a reliever, it wouldn't be a bad guess to assume that he's stiff in some ways and/or his delivery is violent. That is not the case with Diaz. He has the big fastball and a slider that looks good to me but just as importantly, I think he has the delivery and coordination to throw enough good strikes to be a potential major leaguer.

Dubon in 2016:

Salem: .306/.387/.390, 14 XBH, 0 home runs in 279 PA
Portland: .339/.371/.538, 32 XBH, 6 home runs in 270 PA

Can't wait to see how he does in 2017. Here's hoping he'll pull a Mookie and continue hitting for some power. Either way, he could become a nice trade chip.
