YearComment
2019  Due to publishing agreements, the 2019 player comments and team essays are only available in the Baseball Prospectus 2019 book (available in hardcopy, and soon e-book and Kindle).
2018 Now this is what a no. 3 starter looks like. Gonsalves has marched steadily through the minors and polished off Double-A last summer before dipping his toe in the International League. Along the way he’s flashed solid command of a low-90s fastball along with a plus changeup that proofs him against huge platoon splits and a curveball that’s more than just a show-me pitch. Gonsalves has an ideal starter’s frame and an easy three-quarters delivery that he repeats well, allowing him to command his offerings to both sides of the plate. If he keeps his normal schedule and makes strides with his control he should solve Triple-A by Independence Day and could be a boost to the rotation down the stretch.
2017 From the moment the Twins drafted Gonsalves out of a California high school in 2013 his numbers have been excellent, but his fastball command has been singled out as a long-term worry. Last season he held opponents to a .179 batting average and just three homers in 549 plate appearances, while reaching Double-A as a 21-year-old. All of that, along with struggling to keep a walk rate under 4.0 at every level, usually comes attached to a fire-baller’s profile, but Gonsalves’ fastball resides in the low-90s. He’s a good prospect—arguably the best the Twins have remaining in the high minors—but an uncommon stuff/stats mix makes him tough to project with confidence.
2016 Midseason promotions are important, especially for pitching prospects. Developmental momentum is real, and progression doesn't always line up with the progress of the earth around the sun. When Gonsalves proved his long levers and advanced changeup were too much for Midwest League hitters, the Twins made the right call by promoting him to their High-A affiliate. Alas, even correct decisions are often fraught with risk, and pitching prospects are always, always fraught with risk. Gonsalves hit a serious speed bump in Fort Myers. His stuff didn't back up, and he didn't lose his command; he just found himself a weapon short. Until he finds consistency with a breaking ball, it will stay that way. The good news is that by the end of the season, a sharp curveball was starting to take shape, and he had a few very strong outings.
2015 He doesn't get as much press as the more high-profile arms in the Minnesota system, but don't sleep on Gonsalves. The Twins nabbed the California prep product when he slipped to the fourth round of the 2013 draft and have been rewarded with steady progress and the promise of better things to come. Long and lean, Gonsalves is growing into his frame and posted a 4:1 strikeout-to-walk ratio last year as a teenager in the Midwest League. His breaking ball is still on back order, but his fastball can reach the low-90s and his changeup flashes plus, which helped him hold righty batters to a .220/.284/.292 line. The Twins will stretch him out in the low minors this year, and if Gonsalves continues to progress he'll take a big leap up the prospect charts.
2014 Minnesota looked past his marijuana-related high school suspension and inconsistent production and took Stephen Gonsalves in the fourth round of last summer’s draft; the young lefty rewarded their faith with a dominant debut in rookie ball, and, with good lefty velocity and a starter’s frame, he could become a mid-rotation workhorse if his secondary stuff and command develop.

DateQuestionAnswer
2018-05-17 13:00:00 (link to chat)once adrian beltre shows he is healthy for a few weeks would he be able to top 101 type prospect like Stephen Gonsalves?
(a.j. from las vegas)		So, the way I'm reading this is that you're asking if Beltre could return a Top 101-type player in a pre-deadline trade once the Rangers decide to start stripping the team down? Honestly, I kind of doubt it. Most of the teams that I'd guess will be in contention for playoff spots will be well-positioned at the hot corner, not to mention the fact that Manny Machado is likely to be on the trade market as well. Combine that with Beltre's injury woes recently and the fact that he's a really important part of Texas' clubhouse, and I'm not certain he'd pull back enough value to make Texas willing to deal him. (And that's even without Joey Gallo's reticence to return to third base.)

The one team where *maybe* I could see a fit would be Cleveland, and I'm not sure they'd give up a player of Shane Bieber's caliber in that rental dea. (Bryan Grosnick)
2017-08-16 13:00:00 (link to chat)Stephen Gonsalves and Jack Flaherty continue to tear it up in the minors. Do you see either receiving a September call up and making an impact at the major league level?
(Tap Dancer from There)		Gonsalves just got to Rochester, so I wouldn't expect his call up to be imminent unless he continues to dominate. It looks like he's well below his innings output from last season, so if they keep hanging around the WC race, he could be an interesting option.

I'd be more surprised if Flaherty gets a call this year, with their rotation looking a little more crowded and Luke Weaver likely being the next in line at the Triple-A level. (Mark Barry)
2016-08-18 13:00:00 (link to chat)What do you see as the floor/ceiling for Stephen Gonsalves. The numbers seem to just keep getting better.
(RDBL2014 from Concord, CA)		I think he can be a third starter, and I think the floor is backend guy. He was a guy I liked in high school that slipped for various reasons, and some of those reasons had nothing to do with pitching. I think both the fastball and change end up plus, and there are two other usable pitches here. (Christopher Crawford)
2016-05-12 13:00:00 (link to chat)Hey Chris. Was hoping to get your thoughts on some Low Minor Pitchers off to strong starts: Stephen Gonsalves & Mitch Keller? Should there strong start adjust our perspectives on them or too early?
(Jerry from Earth)		Both are people you should be paying attention to, in particular Keller. He showed filthy stuff as a prep in Iowa, and flashes of brilliance (and a lot of not so brilliant) as a pro. It really seems to be coming together, and it gives the Pirates ANOTHER potential stud in their rotation. They're getting good at this. (Christopher Crawford)
2016-04-28 13:00:00 (link to chat)Completely different players, but what do you see as the likely outcome/ceiling for Trey Mancini and Stephen Gonsalves?
(Jeremy from NYC)		I appreciate the attempt here to abjure what is likely a fantasy baseball question, because, yes, they are close to as different a prospect couplet as you could pen. Gonsalves feels pretty close to "peak Twins pitcher" as a prospect, but I am not a big fan of that type of profile. Sure, he could turn into a strikethrowing 4 if the curve gets a bit better, but he's a long way away and feels more like a generic swingman type. Mancini is closer to the majors, and, you know, a first baseman, but he also probably has a role 5 type OFP. It is easier to wring major league value out of the 6'5 lefty arm than the first baseman though if both don't quite get there. (Jeffrey Paternostro)
2016-03-04 13:00:00 (link to chat)Mr. Karaman. Any chance you can shed some light on Michael Kopech, Triston McKenzie & Stephen Gonsalves. Or are these pitching prospects not worth the time.
(David from Atlantis)		Yep. Kopech's got the nastiest front to his arsenal:

McKenzie: http://www.baseballprospectus.com/article.php?articleid=28224
Gonsalves didn't make our Twins list (that system is deeeep), but he's a guy that could emerge quickly if he can develop a breaking ball. (Wilson Karaman)
2016-03-03 13:00:00 (link to chat)Mr. Crawford. Any chance you can hit us with some knowledge on Michael Kopech, Triston McKenzie & Michael Gonsalves. Or was it stupid to even bother you with.
(David from Atlantis)		It's only stupid to bother me if I haven't eaten and/or am sleepy. I'm only one of the two right now so that's okay.

Kopech is fun; plus-plus fastball, plus slider, feel for missing bats. If the change can be more than a third pitch/he can throw enough strikes, he could be a No. 2. Nonzero chance he ends up in the bullpen, however.

McKenzie is almost entirely projection, but projection is fun. A chance for three above-average pitches, learning to repeat the delivery. I just don't know if he'll be durable enough to pitch in a rotation.

I assume you mean Stephen Gonsalves here, and he's also fun. Gets downhill with the fastball, plus change. Just needs to show more consistency with the breaking ball and he's a mid-rotation guy, too. (Christopher Crawford)
2015-06-18 13:00:00 (link to chat)What's the word on Stephen Gonsalves? Seems to be having a breakout year...ceiling of a 2nd or 3rd starter?
(Mike from Detroit)		Haven't seen him, haven't asked around about him. That does appear to be his ceiling though. (R.J. Anderson)
2015-05-27 14:00:00 (link to chat)What do you know about Stephen Gonsalves? Stuff to match the numbers?
(SG from Phila)		He is just outside their top 10 for me. I think he could be a little something but not what the numbers indicate. Kind of like a Ben Lively situation last year. (CJ Wittmann)
2015-06-02 18:00:00 (link to chat)Who do you think has the bigger upside between Casey Meisner and Stephen Gonsalves?
(RDBL2014 from Concord, CA)		I think Meisner has more upside but I would still rather have Gonsalves. Meisner's done good work on his command early and if he can get his body under control he's going to jump up lists. That said I think Gonsalves has shown a lot in his own right so far in 2015 and he has three pitches that can be major league quality. (Mauricio Rubio)
2015-02-25 14:00:00 (link to chat)Stephen Gonsalves...prospect or suspect? Why?
(myonkosk from Norfolk)		Our internal discussions were pretty interesting along those lines! I haven't seen him, so not a whole lot to add, but plenty of people seem to think he's turned a corner/figured something out. (Al Skorupa)
2013-07-12 19:30:00 (link to chat)Thanks for the chat, Nick. Do you think Stephen Gonsalves will be a nice steal pick for Twins?
(Byron from Taiwan)		I think he got more money than his profile deserved, so I wouldn't label his signing a steal. That said, he's an arm that looked like a potential Day 1 talent during the summer scouting circuit, so even with the uneven spring it's nice to bring in the talent as a 4th rounder. I will say that, at least with respect to the evaluators I spoke with about Gonsalves, he's a highly divisive profile. More my money, I would have let him go to school. But the Twins weren't alone in thinking he was work some jingle -- especially in this class. (Nick Faleris on Draft Signing Day)
