Royce Lewis Has Arrived in Grand Fashion

We haven’t seen much of Royce Lewis at the major league level yet, thanks in large part to a twice-torn anterior cruciate ligament. But what we have seen of the first pick of the 2017 draft has been impressive and, lately, otherworldly. On Monday against the Guardians, the Twins’ third baseman clubbed his third grand slam in an eight-game span, part of a longer hot streak that includes seven homers in his past 14 games.

Lewis’ latest slam came at the expense of Lucas Giolito, who was making his debut for the Guardians after being claimed off waivers from the Angels on September 1. Already down 2–0 in the second inning, Giolito was one strike away from a 1-2-3 inning when he lost the plot, issuing three walks, throwing a wild pitch, and allowing a single. That left the bases loaded for Lewis, who had already singled in the first inning. Giolito fell behind 2–0, then left Lewis a 92-mph belt-high fastball on the inner third of the plate. He hit a towering shot to left field; its 107.6-mph exit velocity was garden variety, but that 41-degree launch angle was majestic:

The slam broke the game open. Lewis would later add a two-run single off David Fry — the Guardians’ utilityman threw four innings of thankless relief — in what turned out to be a 20–6 romp. Those six RBIs gave Lewis 10 in a two-game span, as he went 3-for-5 with a three-run homer (off Jon Gray) and four runs driven in in the Twins’ 6–5 loss to the Rangers on Sunday. Only one player, the Orioles’ Ryan Mountcastle, has collected more RBIs in a two-game span this season (11 on April 10–11).

Lewis’ previous grand slams came at the expense of the Rangers’ Chris Stratton on August 27 and the Guardians’ Xzavion Curry on August 28:

The trio of salamis ties Lewis for this year’s lead alongside the Dodgers’ Max Muncy, the Astros’ Alex Bregman, and the Rangers’ Adolis García. Via the Elias Bureau and MLB.com’s Sarah Langs, he’s the first rookie with three grand slams in a span of eight games or fewer, and just the fourth player to bunch three such hits so closely, joining the Yankees’ Lou Gehrig (five games in 1931), the Tigers’ Jim Northrup (four games in 1968), and the Rangers’ Larry Parrish (eight games in 1982).

Including homers on August 23 (off the Brewers’ Corbin Burnes), August 24 (also off Stratton), and August 29 (off the Guardians’ Hunter Gaddis), Lewis is hitting .321/.400/.736 with seven homers and 22 RBI in 60 plate appearances over his last 14 games, all against the Brewers, Guardians, and Rangers. It’s a remarkable surge even from a player who has wielded a potent bat when available… but has unfortunately been rather scarce in recent years.

Recall that after reaching Double-A in 2019 and spending the following season at the Twins’ alternate training site, Lewis first tore his right ACL in February ’21 and missed the entire season. He was ready to go for the start of 2022 and bounced up and down between Triple-A St. Paul and the majors for the season’s first two months, making his major league debut on May 6 but playing just 11 games before returning to Triple-A. After another 10 games down on the farm, he returned to the majors on May 29, but three innings into what was his first major league appearance in center field, he re-tore his ACL — partially this time, not fully as in the first time — making a leaping catch at the wall and missed the rest of the season. For his time with the Twins, he hit a tantalizing .300/.317/.550 in 41 PA.

Lewis made his 2023 debut with Double-A Wichita on May 11 and, after two games, returned to St. Paul. After homering four times in eight games, he was back in Minnesota. Exactly one year after his last ACL tear, and one week before his 24th birthday, he homered off the Astros’ J.P. France in his second plate appearance, then added a game-tying single in the ninth. He played regularly at third base throughout June but strained an oblique on July 1, which sidelined him until August 15. He was hitting well before the injury, and he’s hit even better since coming back:

As you can see from those improved strikeout and walk rates, Lewis has taken a more disciplined approach since returning. He’s lowered his chase rate from 38.6% to 32.2% and his swing rate from 50.8% to 46.2%; meanwhile, his swinging-strike rate has dropped from 13.3% to 9.7%. He’s done a much better job upon reaching two strikes than before, improving from .220/.264/.280 (51 wRC+) with a 52.8% strikeout rate to .231/.333/.333 (91 wRC+) with a 33.3% strikeout rate. In late June, he spoke of adjusting his two-strike approach to a more aggressive, contact-oriented one. Via The Athletic’s Dan Hayes:

“It’s who I am,” Lewis said. “It’s just me being able to put the bat on the ball and make contact and make people do things. You’ve just got to play the game and when you strike out, no one is doing anything except for the pitcher. Honestly, I get frustrated after a while and I just go back to being like — what I said to (hitting coach David Popkins) is, ‘I’m going to turn into (Luis) Arraez today, just touch the ball. There’s a lot of grass out there.’”

…“It’s a mindset,” Lewis said. “Not waiting for a pitch you can drive because these guys are going to execute. If they dot one up on the outer third, that’s 0-1. Then they do it again, 0-2. ‘OK, great, now you’re 0-2.’ Now you’re battling and you’re looking for a pitch to drive at the same time, that doesn’t work. I looked at where some of our plans were going and how the pitchers were pitching us and they weren’t attacking us with our plan of getting a mistake. I was like, ‘Why don’t I just start being aggressive, putting the ball in play? I know I can at least touch it and go to right field.’”

Since returning, Lewis is hitting the ball in the air far more often, and harder in general:

Note that Lewis is also pulling the ball more frequently and, as that last column illustrates, has more than doubled the frequency with which he hits fly balls in the air. Five of his 11 homers have come via pulled flies, one before the injury and four since returning.

For all of that, it’s worth noting that Lewis is riding a .368 BABIP, which is higher than any batting title qualifier save for Freddie Freeman (.375). That said, 15 other players with between 150–425 PA (around enough to qualify) have higher marks, including three of Lewis’ teammates and another former number one pick whom I checked in on about six weeks ago:

When I wrote about Moniak, who’s in the midst of a breakout year with the Angels (despite a 2.8% walk rate and 34.8% strikeout rate), he had a .427 BABIP through 165 PA. Since then, through his next 151 PA, he’s produced a .365 BABIP — still incredibly high, just a bit behind Lewis, yet 72 points lower than that first stretch. That said, Julien, Solano, and Jeffers all have higher BABIPs than Lewis in at least 96 more PA, with Solano having more than twice as many PA.

It’s rare but not unheard of for so many teammates to sustain such numbers. Four other expansion-era teams have had four players with at least a .360 BABIP in 150 PA; in fact, the Twins entry in that group sustained those BABIPs through at least 350 PA for all four:

Moving beyond BABIP, Lewis is actually further ahead of his Statcast expected numbers than just about any player at the 150 PA cutoff:

Lewis has the highest wOBA-xwOBA differential by a seven-point margin, the third-largest differential in batting average, and the fourth-largest in slugging percentage. Note that the top six players in that table are all short of qualifying for the batting title; those gaps tend to shrink as the sample sizes increase.

While it’s tempting to chalk up some of the differentials to Lewis’ 76th-percentile speed, his eight hits on grounders and line drives that have stayed in the infield don’t move the needle that much, and none of his five doubles are the result of hustling to stretch singles. On the contrary, a 398-footer that he hit off the Rangers’ Andrew Heaney at Target Field on August 24 would have been a home run in 24 of the other 29 ballparks.

Even if his production is a bit beyond the bounds of sustainability, Lewis’ return has helped to shore up the Twins’ third base situation. The team made the Replacement Level Killers list ahead of the trade deadline, with Jose Miranda, Kyle Farmer, Willi Castro, and Solano combining with Lewis’ first stint to hit a meek .247/.317/.353 for a 90 wRC+ and 0.5 WAR. With Lewis making 14 of the team’s last 18 starts at third (plus four more at DH) and Jorge Polanco, Castro, and Farmer seeing time in the period between that article’s publication and Lewis’ return, the group is up to .260/.333/.388 (101 wRC+) with 1.8 WAR. The Twins have widened their AL Central lead from three games to seven since that list ran and from 4.5 games to seven since Lewis’ return. He’s just been part of the parade, as the Twins as a team have hit .275/.362/.489 since August 15, good for a 134 wRC+ (fourth in the majors) and 6.42 runs per game (third).

On a team whose biggest stars, namely Carlos Correa and Byron Buxton, have disappointed, Lewis has helped pick up the slack, and if what he’s done isn’t as sustainable as it is flashy, his in-season evolution is certainly encouraging. After three mostly lost seasons, the Twins can’t ask for much more than that.
