Prospects of the Week for Chicago Cubs Affiliates of the Week 5/15-5/21

Taking a look at the Chicago Cubs prospects that have stood out over the past week of games for the team's minor-league affiliates.

AAA Hitter of the week

OF Yonathan Perlaza (24 Years Old)

.357/.400/.571 1 BB, 3 2B, 3 R, 1-1 SB

This could easily have gone to Nelson Velazquez this week. Velazquez had more games played, more plate appearances, more hits and more runs scored. However, Perlaza hit the ball harder, and when you can say that when comparing someone with Velazquez (whose calling card is his power) that’s saying something. 

Perlaza strikes out too much. He has a career K% around 25% which isn’t going to hack it at the major league level. That being said, he’s had a WRC+ over 100 every year since 2019, and outside of the COVID season, he’s moved up a level every year since then as well, never letting his K rates nor BB rates change much. The problem this year (compared to the previous two seasons) is that Perlaza’s ISO which had been as high as .236 last year for AA Tennessee, is down closer to his career expectations at .183. 

This week that wasn’t the case though. Perlaza had a .234 ISO as he hit three doubles and stole a base on his only attempt. He’s a switch hitter with a fair amount of pop (23 homers in AA last season) and enough speed to be dangerous (on pace for more than 30 SBs this year). If he continues to have weeks like this one, he could be a name we hear at Wrigley sooner rather than later.

AAA Pitcher of the week

RHP Hayden Wesneski (25 Years Old)

1 G, 5 IP, 0.00 ERA, 0 H, 4 BB, 5 K

It’s hard to pick a pitcher of the week when so many guys only go one time, but this week it was easy. Could it have gone to Kyle Hendricks and his stellar outing just a few hours earlier that our own Maddie Hartley wrote about recently? Sure. But at this point in his career Cubs fans know who Kyle Hendricks is. That hasn’t been the case with Wesneski.

I won’t lie, when the Cubs traded five years of team control of Scott Effross and his funky delivery for a mid-tier prospect (even one in the Yankees system), I was a little frustrated. In my opinion at the time, the best-case scenario for such a prospect was for him to be what Effross already was. 

Then came Spring Training and Wesneski had all of us wondering if he could instantly become a part of the rotation. 

Then came the up-and-down start to the regular season in which he looked like a legitimate major league starter against the lowly Oakland A’s, but looked completely overmatched by the likes of Seattle (couldn’t get out of the second inning) and most recently Minnesota (served up four home runs). 

Hopefully, this week is a sign of the next chapter beginning because he was literally unhittable on Saturday night. The walks are concerning, sure, but the Cubs have a 25-year-old mid-rotation starter sitting in Iowa, hungry for his next chance at the Bigs and I can’t remember that being the case in the last decade (if not longer).

AA Hitter of the week

3B BJ Murray (23 Years Old)

.476/.522/.952 2 BB, 5 2B, 1 3B, 1 HR, 4 RBI, 6 R

Hopefully, there is a performance like this every week that makes the decision easy as to who gets player of the week honors. BJ Murray was simply spectacular. He had seven extra-base hits in five games. While he doesn’t appear on any top prospect lists (yet), he did get a shout-out in a recent article by Jim Bowden for the Athletic in which he looked at “27 Prospects You Don’t Know Yet, But Should.”

There’s a lot to like when you look at Murray, and whatever you don’t like can usually be offset by what you do. Does he strike out a lot? Yes. He has 38 strikeouts on the year at AA. Does he offset that by walking at a high rate as well? Yes. He’s walked 28 times this season. 

He’s competitive and plays a competent 3B, even on the biggest stage this summer as he played for Great Britain in the World Baseball Classic. 

His bat was always going to be what got him to the majors, and he’s never had a WRC+ under 113, but this year he’s blowing the doors off of all of his previous numbers. His BABIP may seem high at .341 but it’s actually below his career average, which implies that his early results aren’t lucky, they’re just good. He’s got a .433 wOBA and a 167 WRC+ and he doesn’t appear to be slowing down anytime soon. 

If this week is a sign of things to come, then expect to see BJ Murray not only climbing prospect lists, but also climbing the Cubs Minor League ladder to Iowa before the end of the year.

AA Pitcher of the week

LHP Jordan Wicks (23 Years Old)

1 G, 5 IP, 1.80 ERA, 2 H, 0 BB, 5 K

Jordan Wicks had a great start this week and that’s what landed him on the list. So far, he’s 3-0 across 35.1 IP with a 2.55 ERA, so this week’s start isn’t out of the norm for the way that he’s pitched this year, but that doesn’t mean it’s not worth celebrating. 

Since they drafted him out of Kansas State, the Cubs knew what they were getting out of Wicks and the word high comes up often: high K, high BB, high ceiling, high floor as a high leverage reliever. 

He hasn’t disappointed this season, and I’d argue he didn’t disappoint last year either as much as he was just unlucky and the results weren’t as favorable as they should have been.

Wicks pitched 28 innings at AA to end last season with the following stat line

Wicks has pitched 35.1 innings at AA to start this season with the following stat line:

There is a lot there to suggest that Wicks was unlucky last year and that there’s even more room for improvement this season.

There are two obvious reasons that Wicks has seen an improvement in his ERA this season and that is that he’s limited the walks and he’s limited the home runs. Last season more than 21% of the balls hit in the air against him were home runs. That was completely insane. That being said, having a 77% strand rate to pair with a 47.8% ground ball rate and 28.9% strikeout rate made it pretty tough to score against him unless the opposition hit a home run, so it makes sense that this year it would regress to the mean a little bit.

If Wicks can continue to strikeout batters at this clip and limit the walks and homers against him then it’s within reason to think that he could get even better in his next couple of starts before a late-season call-up to Iowa where he’ll only be one call away from making his major league debut.

A Hitter of the week

2B Juan Mora (23 Years Old)

.467/.579/.667 2 BB, 3 2B, 3 RBI, 5 R, 2-3 SB

Mora started the season at High-A South Bend and appeared overmatched. He went on the Developmental List and was reinstated to Myrtle Beach a couple of weeks ago and hasn’t looked back since. 

In eight games at High-A Mora had a .115/.233/.154 slash line. In the nine games at Low-A Mora has had a .481/.548/.630 slash line. Whatever the Cubs are doing on the Developmental List it seems like it’s working.

Even compared to the player he was at Low-A last year Mora looks like a completely different player the last couple of weeks. Could this be due to his incredibly bloated .565 BABIP? Yeah, probably. But could it also be due to the fact that he’s figured something out and is striking out at a more manageable 12.9% rate? Sure, let’s hope so!

A Pitcher of the week

RHP Michael Arias (21 Years Old)

1 G, 4 IP, 2.25 ERA, 3 H, 2 BB, 8 K

I feel like I’ve said this a lot lately, but this may be one of my favorite stories in the Cubs minor league system. If you go to Arias’s milb.com page, you’ll find a SS. Not a RHP. The Cubs signed Arias after the Blue Jays gave up on him as a shortstop and have been developing him as a pitcher ever since.

The fastball is good, but it’s the secondary stuff that’s really impressive, specifically the movement on those secondary pitches. That being said, with the nastiness in movement like that his problem has been, and will likely continue to be, the walks. He didn’t escape them this week as he had two walks in four innings, but if he can limit them he can really be a difference-maker. 

According to fangraphs, he threw 192 pitches in 2021, 247 in 2022 and 387 so far in 2023. While he’s improved from a rate of 61% strike throwing in 2021 to 63% so far this year, that’s still nowhere near good enough to find himself climbing the minor league ladder, but if he can figure out how to get closer to 70% and can be effectively wild rather than just wild, he can become an extremely usable high-leverage bullpen piece given the stuff that he has.
