Jacob Wallace Brings a Power Arsenal and Command Issues to Kansas City

The Royals may have gotten a steal when they acquired Jacob Wallace from the Red Sox last week in exchange for Wyatt Mills. The “may have” comes with a sizable caveat, as the 24-year-old right-hander has big-time stuff, but also command issues. Pitching for the Double-A Portland Sea Dogs this year, he walked 49 batters in 56.2 innings.
Wallace is overpowering when he’s in the strike zone, though. The 100th overall pick in 2019 — he was drafted by the Rockies out of the University of Connecticut, then swapped to Boston a year later in exchange for Kevin Pillar — fanned 76 batters and allowed just 35 hits. As Tess Taruskin and Kevin Goldstein wrote last spring, “It’s not too complicated: If he can throw more strikes, he has a path to the big leagues.”
Wallace, who prior to the trade was No. 23 in our Red Sox prospect rankings with a 40 FV, discussed his overpowering arsenal and his mother-influenced interest in pitching analytics late in the season.

David Laurila: Before we talk about your repertoire, you told me that your mother is big into analytics?
Jacob Wallace: “She reads and absorbs everything. She would tell me, ‘Oh, your FIP is this’ — all these numbers — and I’d be like, ‘Well, I have no idea what you’re talking about, I’m just out there playing.’ I’d know my ERA and the other basic stuff, but not the more advanced-stats. This was back in high school. Once I got to college and started learning more… I mean, it was really cool to realize how much she had already learned.”
Laurila: I’m guessing that your mother reads FanGraphs?
Wallace: “Yeah, I would say she does. She is a director of plant operations for [Proctor & Gamble], so numbers and learning are definitely things she definitely loves.” Read the rest of this entry »
