Mookie Who? Tyler O’Neill Is the Hottest Hitter in Baseball

Tyler O’Neill didn’t take lengthy to adapt to a brand new group. Traded to the Purple Sox in December after spending six years with the Cardinals, O’Neill claimed sole possession of a serious league file by homering on Opening Day for the fifth straight season. As we strategy the two-week mark of the season — sure, it’s early — he finds himself atop main leaderboards and has helped Boston get off to a 7-4 begin.

On Tuesday at Fenway Park, O’Neill launched a towering solo shot over the Inexperienced Monster off Orioles ace Corbin Burnes to place the Purple Sox up 1-0 within the first inning:

The Statcast-estimated distance of 413 toes made that O’Neill’s longest of this season to date. It was his sixth homer, momentarily shifting him out of a tie with Mookie Betts, Marcell Ozuna, and Mike Trout, although Trout countered together with his sixth afterward Tuesday night time. Nonetheless, O’Neill has matched Fred Lynn’s scorching 1979 begin for probably the most homers by a Purple Sox participant within the group’s first 11 video games of a season, doing so whereas making simply 9 begins and a pinch-hitting look. By comparability, final season O’Neill didn’t hit his sixth dwelling run till August 11, and completed with simply 9 in 72 video games.

O’Neill started the season by homering off Mariners reliever Cody Bolton on Opening Day in Seattle. In doing so, he broke a tie with Yogi Berra (1955–58), Gary Carter (1977–80) and Todd Hundley (1994–97) for probably the most consecutive Opening Day video games with a house run. (And also you thought you have been glad baseball was again!) He closed out the Seattle sequence with a homer off Bryce Miller on March 31, took the Angels’ Griffin Canning and José Soriano deep on April 5, then added a dinger in opposition to Chase Silseth on April 7.

Sadly for the Purple Sox, O’Neill’s blast on Tuesday was their solely run of the day; they misplaced 7-1. And oddly sufficient, the 28-year-old left fielder hasn’t pushed in anybody else regardless of his six dwelling runs, which is extra a commentary on his teammates than his personal failings; he’s 1-for-3 with a pair of walks with runners in scoring place. No matter his RBI complete, he’s swinging a very popular bat total, hitting .344/.488/.906. It’s not day-after-day you’re miles forward of two future Corridor of Famers for the foremost league lead in key classes, so we’ll notice that his slugging proportion is 126 factors forward of the second-ranked Trout, and his 276 wRC+ is 32 factors forward of the second-ranked Betts. In the meantime his on-base proportion merely leads the American League.

In fact, O’Neill has performed simply 10 video games, the primary 9 of them in opposition to the Mariners, A’s, and Angels — all on the highway — and there’s solely a lot we will take from that, however the primary factor is that he’s wholesome, and that’s a giant one, as a result of save for his monster 2021 season and his brawny physique (“listed at 5-foot-11 and 200 kilos, of which about 198 kilos is biceps and quads,” wrote Michael Baumann), accidents have largely outlined his profession.

Drafted by the Mariners out of a British Columbia highschool within the third spherical in 2013, O’Neill turned a Cardinal within the Marco Gonzales commerce 4 years later. He debuted within the majors on April 19, 2018, however spent a lot of that season and the subsequent one bouncing backwards and forwards between Triple-A and the majors, with 5 (!) journeys to the injured listing thrown in for good measure. After spending all of 2020 within the majors and on the lively roster — and even successful his first Gold Glove, however hitting a depressing .173/.261/.360 — he lastly bought one thing near a full-length season underneath his belt in 2021, hitting .286/.352/560 (143 wRC+) with 34 homers, 15 steals, and 5.3 WAR in simply 136 video games, however accompanying that with two extra journeys to the IL. He added a second Gold Glove that 12 months, and completed eighth within the NL MVP voting, however since then he hasn’t come near replicating that season, with accidents limiting him to simply 168 video games, 23 homers, a 98 wRC+ and a pair of.0 WAR throughout 2022–23, one other two-year span that included 5 journeys to the IL:

Thus the 28-year-old O’Neill entered this season having performed greater than 100 video games in a serious league season simply as soon as, and greater than 72 simply twice. Between his accidents, a crowded discipline of options, his rising price ticket, and a spat with supervisor Oliver Marmol — who publicly questioned O’Neill’s effort operating the bases throughout a heavy rain final April 4 in St. Louis, calling his effort “unacceptable” — O’Neill fell out of favor in St. Louis. On December 8, the Cardinals traded the pending free agent to the Purple Sox in change for a pair of righty relievers, Nick Robertson and Victor Santos.

Up to now, the change of surroundings appears to agree with him, although it’s value noting that Tuesday’s recreation was his first at Fenway with the Purple Sox. One recreation, one homer? That’s a reasonably good charge!

In mild of O’Neill’s lengthy historical past of leg woes, it’s value stating that as of now he’s hitting the ball more durable than prior to now two seasons. I current these stats whereas acknowledging that we don’t have sufficient knowledge to attract sturdy conclusions about what’s taking place but; that is as a lot about his decline from 2021 as it’s his torrid begin:

Keep in mind that, as Baseball Prospectus’ Russell Carlton has famous, exit velocity stabilizes round 40 batted ball occasions, and barrel charge at 50 BBE, whereas groundball, fly ball, and hard-hit charges achieve this at 80 BBE. Inside this small pattern, this 12 months’s exit velo and barrel charge at the very least look extra like 2021 than ’22 or ’23. On a rolling foundation of 25 plate appearances, each his xSLG and xwOBA present that his season-opening scorching streak resembles solely two or three stretches from the previous two seasons, whereas he had a handful of such stretches in 2021:

The opposite factor to notice about O’Neill is how a lot he’s tightened his strategy to date. He’s a man with a number of swing-and-miss in his recreation, a lot in order that whilst he ranked no. 61 on our Prime 100 Prospects listing in 2018, he had 30/40 grades (current/future) on his hit software, and from 2018–23, he struck out 30% of the time, seventh amongst hitters with at the very least 1,500 PA in that span. Manufacturing-wise, he’s close to the higher finish amongst guys with strikeout charges in that neighborhood; of the hitters with the 30 highest strikeout charges over at the very least 1,000 PA inside that span — everyone from 28.8% up — his 111 wRC+ ranks fourth, behind solely Luke Voit (123), Giancarlo Stanton (122), and Teoscar Hernández (117).

Coming into this season, O’Neill had swung at 72.5% of pitches throughout the strike zone, together with 71% final 12 months; to date this 12 months, he’s minimize that right down to 50.8%. Equally, his total swing charge of 48.1% getting into this 12 months (44.9% final 12 months) is right down to 36%. His swinging strike charge of 15.4% (11.2% final 12 months) is method down to six.4%, and his strikeout charge, which was 25.2% final 12 months, is at 19.5%. Thoughts you, none of those stats have stabilized — swing charge takes about 50 PA (he’s at 41) and strikeout charge requires roughly 60 PA — however these are at the very least promising traits.

We’re clearly nonetheless early sufficient within the season that any pattern may very well be a mirage, a two-week heater or skid that may not benefit nearer scrutiny if it have been situated in mid-June or the canine days of August. Nonetheless, when mixed together with his scorching streak, the well being and change-of-scenery points of O’Neill’s state of affairs are at the very least value keeping track of. He’s not going to proceed slugging .906, however for a group whose outfielders entered this season rating twenty second within the majors with a mixed 96 wRC+ since 2020 — i.e., the post-Betts period — this counts as a welcome growth.
