With the All-Star Game in the rearview, MLB's second half has officially begun, Axios' Jeff Tracy writes.

Let's take a quick tour through each division, five-words-or-fewer style...

AL East: My "bold prediction" in the preseason was simply that Boston would be in the mix down the stretch — not that they'd end the first half with the best record in the AL!

• Red Sox: Chris Sale return imminent.
• Rays: Can Champa Bay keep rolling?
• Blue Jays: Vladito Triple Crown watch.
• Yankees: They'll heat up eventually, right?
• Orioles: Mancini's story is still awesome.

AL Central: The Twins' downfall is frankly flabbergasting. If the Indians get their injured pitchers back before the White Sox get their injured sluggers back, this could be a tight race.

• White Sox: Mercedes gone, legend lives on.
• Indians: Missing Bieber more than Lindor.
• Tigers: Yikes — Miggy's OPS is .648.
• Twins: Nothing gold can stay.
• Royals: Whit and Salvy deserve better.

AL West: Until that division lead reaches double digits, hope remains that Trout's return, Rendon's return-to-form and Ohtani's continued brilliance can yield a playoff berth.

• Astros: No trash cans, still raking.
• A's: Unheralded stars keep delivering.
• Mariners: Avoid playoff drought turning 20?
• Angels: Ohtani — greatest season ever?
• Rangers: Gallo gone by trade deadline.

NL East: Welcome to the only division with fewer than 10 games separating first and last. In fact, the last-place Marlins have a better run differential (+17) than the first-place Mets (+9).

• Mets: Will deGrom become deGOAT?
• Phillies: That bullpen ... 22 blown saves!
• Braves: Losing Acuña was brutal.
• Nationals: Can Soto find power stroke?
• Marlins: Young arms are electric.

NL Central: If Christian Yelich can even remotely approximate his MVP form after a lackluster spring (.768 OPS, 5 HR), Milwaukee looks real dangerous. Cincy is mighty frisky too, though.

• Brewers: Three aces? Good strategy.
• Reds: Sellers rapidly became buyers.
• Cubs: Buyers rapidly became sellers.
• Cardinals: Still stuck in neutral.
• Pirates: Two All-Star starters!

NL West: How 'bout dem Giants?! San Francisco leading the division at the break is easily the biggest surprise of the first half.

• Giants: Brandon Crawford, 34, career year.
• Dodgers: Will Bauer saga become distraction?
• Padres: As good/exciting as promised.
• Rockies: Shipped Arenado; Story next?
• Diamondbacks: Six wins ... since June 2.

Vladimir Guerrero Jr.'s 468-foot bomb helped the American League beat the National League, 5-2, in Tuesday night's MLB All-Star Game.

• MVP: At 22 years, 119 days old, the Blue Jays slugger becomes the youngest MVP in All-Star Game history — 117 days younger than Ken Griffey Jr. was when he won the award in 1992.
• What he's saying: "Ever since I was a kid, I've been thinking about this moment. ... Dad, this is for you."

Like father, like son: The Guerreros are the third father-son combo to homer in the MLB All-Star Game.

• Bonds: Bobby (1973) and Barry (1998, 2002)
• Griffey: Ken Sr. (1980) and Ken Jr. (1992)
• Guerrero: Vlad Sr. (2006) and Vlad Jr. (2021)

The big picture: The AL has won the last eight All-Star Games, tying the second-longest win streak in history (NL won eight straight from 1963 to 1970). The longest win streak? 11 games, set by the NL from 1972 to 1982.

👀 Shohei Ohtani watch ... MLB's first two-way All-Star threw a perfect first inning (fastball topped out at 100.2 mph) and was rewarded with the win. He was 0-for-2 at the plate.

Infectious disease experts say the Tokyo Olympics don't have strong enough protocols for testing or ventilation, either in competition venues or in the Olympic village, Axios' Tina Reed reports.

The state of play: The IOC's playbook calls for attendees to physically distance themselves from others, wear masks, and get tested daily. They're also required to use a contact tracing app on their smartphones.

• But it'll be too easy for cases to slip through the cracks and then spread, said Annie Sparrow, a professor at the Icahn School of Medicine at Mount Sinai Hospital.
• Some IOC suggestions — athletes should open windows in the Olympic Village every 30 minutes — aren't supported by science, said Michael Osterholm, infectious disease expert at the University of Minnesota.

The backdrop: Other sports organizations have navigated this successfully, but experts said the IOC's precautions simply aren't as strong as those employed last year by the NFL or the NBA.

• "I think [the NFL] understood the concept of airborne transmission and what it meant and they planned accordingly," said Osterholm, who helped advise the NFL's safety precautions.
• "What about the workers, the volunteers ... exposed for 14 to 16 hours a day who are going into the [Olympic] village and then going back home to their families?" said Sparrow, who helped advise the WNBA through the pandemic.

Tonight's WNBA All-Star Game (7pm ET, ESPN) pits Team USA against Team WNBA in a star-studded matchup that doubles as an Olympic tune-up, Jeff writes.

"This game is gonna be more than just the regular All-Star Game ... We're out there with a mission. We're going to use this game to get ready."

Team USA: South Carolina's Dawn Staley, who played for the 1996 team that won the first of six straight gold medals, is Team USA's coach.

• Returning Olympians: Sue Bird (5x), Diana Taurasi (5x), Sylvia Fowles (4x), Tina Charles (3x), Brittney Griner (2x), Breanna Stewart (2x)
• First-time Olympians: A'ja Wilson, Ariel Atkins, Napheesa Collier, Skylar Diggins-Smith, Chelsea Gray, Jewell Loyd

Team WNBA: Lisa Leslie and Tina Thompson — Hall of Famers with a combined 17 All-Star Game appearances, six WNBA titles and six Olympic gold medals — are co-coaching Team WNBA.

• Returning All-Stars: Candace Parker (6x), Liz Cambage (4x), DeWanna Bonner (4x), Jonquel Jones (3x), Courtney Vandersloot (3x)
• First-time All-Stars: Brionna Jones, Kahleah Copper, Dearica Hamby, Arike Ogunbowale, Betnijah Laney, Courtney Williams, Satou Sabally

Sungjae Im and Si Woo Kim of South Korea have withdrawn from The Open Championship this week to focus on the Olympics.

Why it matters: South Korean athletes who win an Olympic medal are able to forgo an 18-month military stint, which is mandatory for males between ages 18–28. Talk about stakes.

• Sangmoon Bae, who was ranked 26th in the world in 2015 when he returned to South Korea to complete his military service, hasn't been the same player since.
• K.J. Choi, once the only South Korean playing full time on the PGA Tour, completed his military requirements before turning pro.

The big picture: Military strength has long been a priority in South Korea, where the threat from North Korea is always looming.

• Yes, but: The country's pool of eligible enlistees is shrinking fast due to South Korea having the developed world's lowest birthrate, per WSJ (subscription).

Lachlan Morton, an Australian adventure racer, completed his solo Tour de France on Tuesday morning — rolling into the Champs-Élysées five days before the Tour peloton is set to arrive.

To complete his solo trip, Morton spent 220 hours in the saddle over 18 days, covering 3,424 miles (60% longer than the regular Tour de France) and climbing nearly 215,000 feet.

He slept outdoors in a damp sleeping bag and ate only what he could buy along the way at gas stations and cafes. Guy's a legend.

70 years ago today, CBS televised the first ever sporting event in color — a horse race in Oceanport, New Jersey, called the Molly Pitcher Handicap.

The backdrop: The color TV war reached a head in 1950, when the FCC approved CBS' technology but not RCA's. Incensed, RCA filed an injunction, effectively hamstringing CBS.

• But in the spring of 1951, the U.S. Supreme Court ruled in favor of the FCC and CBS, paving the way for television's technicolor future.

The aftermath: CBS' victory was short-lived. They were first to market, but had the inferior product — not only was the picture fuzzy, but the system worked only with new color TV sets, which few people had.

• By 1953, RCA's superior product was approved, but widespread adoption was still a long way off due to high expenses for consumers (purchasing a set) and broadcasters (converting to color transmission).
• By 1965, the color revolution came at last after a study showed it would significantly increase ratings. By the end of the decade, networks broadcast everything in color.
