I’m happy with our kids in Lansing. Kirk has demonstrated a solid hit tool and plays a fair defensive catcher. There are some concerns though if you wanna compare him to Groshans as who is a better hitting prospect.
First I would point out Groshans is going through his first full year as a pro ball player, literally still in high school 12 months ago. Kirk was signed internationally out of Mexico in 2016, got into a car accident, broke his hand when hit by a pitch and lost a full season. But despite that he’s had more time to marinate under Blue Jays coaches/trainers whereas this is Groshans first rodeo drafted in 2018.
Groshans has an ideal body type for an infield prospect, 6-3 205lbs. Most likely third baseman but potential at SS/2B.
Where Kirk has a lot of question marks being 5-9 250lbs. Weight issues aside, he does not have the towering power like Rowdy Tellez standing 6-4 220lbs (prob closer to 250). Though Kirk has demonstrated HR potential and good SLG% in Lansing, when I watch his swing I don’t see an elite power hitter at the plate—he’s got some bat speed but it’s more tuned towards contact. Standing only 5-9, He obvious can’t generate the same type of loft compared to Tellez, or the consistent 110mph+ exit velos. But his bat speed also doesn’t scream power hitter, like his teammate Groshans.
“Why is this an issue? Kirk can hit. Who cares if he doesn’t hit for power.”
The problem is, as of right now, Kirk is a dead pull hitter. Once he goes up the system with better pitchers and fielders preventing base hits, if he can’t start using all fields or generate exit velocities he will have a hard time getting the same success at the plate. Let’s see what happens when he gets shifted every AB.
However his walk numbers and lack of strikeouts are very encouraging and indicative of good plate discipline. But it’s also A ball, where many pitchers have no command or even a premium breaking ball that is thrown for strikes.
Groshans on the other hand, his bat speed is ELITE for his age. It’s difficult to project a 19 year old but he doesn’t look overmatched playing against older kids in the Midwest league. He has a good approach, and his power tool has been well documented since his draft scouting reports. But his above average hit tool has been a pleasant surprise. For a power hitter, his 19% K rate is very reasonably supported by a 13% walk rate. And unlike Kirk, he uses all fields having pulled 40% and oppo 40%. Groshans has also demonstrated a really good arm and athleticism to possibly stick at short, though most draft scouting reports project him at third.
You also look at his swing, the way he strides and generates power you really can see a young Josh Donaldson there. He has middle-of-the-order bat written and stamped on his forehead. The talent there is obvious. You bundle that whole package together, with those tools, that frame, at that age. You have a legit top 100 prospect no questions.
