Walker Jenkins called up by Twins as Byron Buxton sits with hip impingement

What happened

Walker Jenkins, the Minnesota Twins' top prospect, is in the major leagues. The Twins called up the 21-year-old center fielder after Byron Buxton was sidelined by a hip impingement with no timetable for his return, per FanGraphs. Jenkins started in center field for all three games of Minnesota's weekend series against the White Sox, stepping into the vacancy left by one of the more injury-tested outfielders in the game — which, as it turns out, is a role Jenkins has some personal familiarity with.

Why it matters

The fifth pick in the 2023 draft does not arrive as a depth placeholder. Jenkins was hitting .308/.407/.532 with a 142 wRC+ across 69 games for the Triple-A St. Paul Saints when he received the call, per FanGraphs. Those are numbers that tend to make a front office stop asking whether a prospect is ready and start asking why they waited this long. FanGraphs noted that Jenkins was looking like a hitter who didn't have much more to learn from facing Triple-A pitching — which is the polite way of saying the assignment had run its course.

The positional fit is clean. Buxton is a center fielder. Jenkins is a center fielder. The Twins did not need to shuffle the outfield corners or ask a corner bat to cover ground he wasn't built to cover. When a roster need and a prospect's profile align that precisely, the call-up tends to feel less like an emergency measure and more like a schedule that got moved up.

The numbers

Jenkins arrived at the big-league level carrying a .308/.407/.532 slash line and a 142 wRC+ in 69 Triple-A games this season, per FanGraphs. The wRC+ figure measures runs created relative to league average — putting his Triple-A production well above the mean. The .532 slugging percentage and .407 on-base percentage together suggest a hitter generating both contact and power, not simply running up a batting average on soft contact.

The road to those numbers was not without detours. Hamstring and quad injuries in 2024 held Jenkins to 82 games, per FanGraphs. An ankle injury then cost him two months of the 2025 season. FanGraphs also noted a shoulder injury sustained when Jenkins collided with outfield wall signage in right-center field. The fact that he reached 69 games for St. Paul before the call came is itself a minor milestone in a career that has spent considerable time in the trainer's room.

Where the club stands

The Twins enter this stretch at 68-74 (.479), sitting third in the AL Central, 6 games back of the division lead. In the Wild Card picture, Minnesota ranks 7th, 3.5 games relative to the cut line — which is the kind of margin that keeps a front office technically alive while also keeping the antacid budget elevated. The club arrives on a one-game winning streak.

The schedule ahead does not offer much breathing room. Minnesota hosts the Detroit Tigers at Target Field on Monday, August 31, with Taj Bradley taking the ball against Jackson Jobe. The series continues Tuesday, September 1, with Andrew Morris facing Troy Melton, and wraps Wednesday, September 2, with Dean Kremer opposing Drew Anderson. Three games against Detroit, at home, with the Wild Card margin sitting where it sits — the Twins need wins in clusters, not singles.

Is Jenkins the everyday center fielder now?

For as long as Buxton is out, the circumstances FanGraphs described point in that direction. There is no timetable attached to Buxton's hip impingement, which means there is no date on the calendar around which the Twins can plan a rotation. Jenkins started all three games of the White Sox series, which suggests the organization is not treating this as a spot start or a look-see. Whether that continues through the Detroit series and beyond will depend on Buxton's progress, which remains unspecified.

It is worth noting that the general mechanics of the roster are about to shift. Under standard league rules, active rosters expand from 26 to 28 players beginning September 1 — meaning the Twins will have additional flexibility to carry depth without the same zero-sum tradeoffs that defined the August call-up. That does not change Jenkins' role, but it does change the arithmetic around him.

The injury history worth knowing

FanGraphs flagged something that Twins fans will recognize as a recurring theme: Jenkins reportedly shares Byron Buxton's tendency to find the injured list. The hamstring and quad injuries in 2024 limited him to 82 games. The ankle injury in 2025 cost him two months. The shoulder injury from the right-center wall collision added another chapter to a prospect biography that reads, at times, like a medical reference text with baseball statistics in the footnotes.

The Twins are now running a center field situation in which the incumbent is out indefinitely and his replacement has his own history of interrupted seasons. That is not a knock on Jenkins — it is simply the operational reality the club is managing. The hope, presumably, is that the two injury timelines do not overlap any more than they already have.

What we don't know yet

Buxton's hip impingement carries no timetable, per FanGraphs. That is the central uncertainty hanging over this entire situation. Until that changes, the depth chart in center field belongs to Jenkins by default.

It is also worth noting that FanGraphs reported this as a prospect call-up driven by roster need — not as a formal club announcement of a long-term role or a service-time decision. The framing is situational. Whether the Twins view this as a permanent promotion or a bridge arrangement is not something the available material answers.

What to watch

The Detroit series starting Monday is the immediate test. Jenkins will be playing center field at Target Field against a Tigers rotation that includes Jackson Jobe, Troy Melton, and Drew Anderson — three pitchers he has not faced at the major-league level. How he handles that exposure, both at the plate and in the field, will tell the Twins something they cannot learn from Triple-A box scores.

The other variable is Buxton. Any update on his hip impingement — a rehab assignment, a return to baseball activities, a transfer to the 60-day IL — would reshape the outfield picture immediately. For now, the Twins are running with what they have: a 21-year-old with a 142 wRC+ and a résumé that already includes more time on the injured list than most prospects accumulate in a full career. The numbers say he belongs. The schedule says he'll find out quickly.
