Colorado Rockies top prospect season review: The Depth

26) Willie MacIver, C, A+/AA/AAA: .220/.314/.390, 92 wRC+, 10.0 BB%, 27.3 K%, 15 HR, 20 SB

Willie MacIver had a rollercoaster of a year. He was incredible in Spokane, tailed off in Hartford, but in between, he appeared in the Futures Game. The backstop also made a late-season appearance in Triple-A.

The upper minors struggles for MacIver are concerning as Double-A pitching stands as a true test for offensive prospects.

Still, the former Washington catcher shows talent in every facet of the game, especially power and defense, with some sneaky speed mixed in.

It’s unclear if MacIver will begin in Double-A or Triple-A but he’s firmly on the Rockies’ radar and likely 4th on their depth chart behind Brian Serven (who just missed my top 50).

27) Mitchell Kilkenny, RHP, A/A+: 3.27 ERA, 4.08 FIP, 1.12 WHIP, 23.2 K%, 4.8 BB%

A 2018 2nd-round pick, Kilkenny finally established himself after fully recovering from Tommy John surgery in the fall of 2019.

He came on with a bang, flashing his elite command which helped limit baserunners and overall damage, evidenced by his 1.12 WHIP and 3.27 ERA.

The former Texas A&M pitcher doesn’t bring the wow factor on the hill with his stuff, but his pitch ability might be the best in the system. Upper minors hitting will stand as a true test for Kilkenny, where he’ll likely start 2021.
