Gymnastics is one of the most popular Olympic sports. But unlike swimming (finish first!) or basketball (score more points!), it can be complex and difficult to follow.

How it works: There are seven individual events for men and five for women.

• Men: Floor exercise, pommel horse, still rings, vault, parallel bars, horizontal bar, individual all-around.
• Women: Floor exercise, vault, uneven bars, balance beam, individual all-around.

Scoring: The "Perfect 10" is a relic of the past. Since 2006, gymnasts earn scores made up of two components — difficulty ("D") and execution ("E").

• Difficulty score: Routines are comprised of skills, and each skill has a pre-assigned value that reflects its difficulty. So the higher the "D" score, the harder the routine was.
• Execution score: This is the grade for how well skills are performed. All "E" scores start at 10.0 and judges take deductions for mistakes, such as wobbles or poor dismounts.

Between the lines: Simone Biles' routines are so difficult that she can afford missteps and still dominate thanks to her huge "D" score. Something to watch: whether Tokyo judges give her moves — which few, if any, gymnasts can do — their proper value.

Of note: While artistic gymnastics is the most well-known discipline, medals will also be awarded in rhythmic gymnastics and trampoline.

Tokyo notes:

• Men's schedule: The team final began early this morning (6am ET, Peacock) and will air on primetime tonight (8pm, NBC). The individual all-around final is on Wednesday.
• Women's schedule: The team final begins early tomorrow morning (6:30am, Peacock) and will air on primetime tomorrow night (8pm, NBC). The individual all-around final is on Thursday.
• Inside the venue: Ariake Gymnastics Centre is a temporary venue. That explains the unfinished wood seats that make it look like the world's biggest IKEA set, Axios' Ina Fried reports from Tokyo.
• Spotted: A jar of honey! Turns out, men use it as a gripping agent for parallel bars.

The 2021 NBA Finals averaged 9.9 million viewers per game, according to Nielsen, Axios' Jeff Tracy writes.

• Why it matters: While that's a 32% increase over last year's Lakers-Heat series in the bubble, it's also the fourth-lowest average this century, ahead of only 2020, 2007 and 2003.
• The backdrop: COVID-19 dramatically altered scheduling. While previous Finals took place in early June, this year's Bucks-Suns series was held in mid-July when networks typically have lower ratings. Last year's series was held in early October.

Of note ... Game 6, the Bucks' clincher, was the fifth-most watched non-football sporting event since the pandemic first arrived, trailing Baylor-Gonzaga (national championship), Gonzaga-UCLA (Final Four), the Kentucky Derby and Game 6 of the World Series.

The Cleveland Indians will change their name to the Guardians at the conclusion of their 2021 season, Jeff writes.

Driving the news: Just six months after announcing a name change was coming, the Indians whittled a list of over 1,000 names down to one, landing on the Guardians.

• The name comes from "the Guardians of Traffic" — the art deco statues carved into the pylons of Cleveland's Hope Memorial Bridge.
• The announcement was made in a video narrated by Tom Hanks, whose career began in Cleveland in the late-1970s, inspiring a lifelong love for the city and its teams.

What they're saying: "I'm sure there will be some pushback," Aaron Payment, vice president of the National Congress of American Indians, told NYT. "But they are on the right side of history and deserve credit for it. This new name closes the books forever on a derogatory name."

The big picture: The Indians and Washington Football Team both acted fast amid 2020's racial reckoning, but their high-profile changes belie the reality of how pervasive racially insensitive mascots remain.

• As of October, 1,232 U.S. high schools still had Native American nicknames, per FiveThirtyEight. But without financial incentives or national media attention, most lack the urgency to make changes.
• Yes, but: The tide may be turning. Four states (California, Maine, Oregon, Wisconsin) already have laws or Department of Education policies prohibiting such mascots, and at least four more have proposed or discussed similar legislation.

The Sabres selected Michigan defenseman Owen Power with the No. 1 pick in this weekend's NHL draft.

Why it matters: This marks the fourth time in NHL history that a college player has gone first overall. Power joins Joe Murphy (1986), Rick DiPietro (2000) and Erik Johnson (2006).

Go Blue: Michigan is the first school to ever have five players (current and committed) selected in the first round of a single draft.

• Current: Matthew Beniers (No. 2, Kraken) and Kent Johnson (No. 5, Blue Jackets) heard their names called shortly after Power.
• Committed: Luke Hughes (No. 4, Devils) and Mackie Samoskevich (No. 24, Panthers) will play for the Wolverines next season.

Draft notes:

• Family affair: Luke is the third Hughes brother to be a first-round pick, joining Jack (No. 1 pick in 2019) and Quinn (No. 7 pick in 2018).
• By country: 14 different countries produced a draft pick, led by Canada (82), the U.S. (50), Russia (29), Sweden (24) and Finland (14).
• Controversial pick: The Canadiens took Logan Mailloux at No. 31, despite the teenager asking teams not to pick him due to a criminal conviction while playing in Sweden.

MLB's latest experiment will see minor-league catchers electronically transmit signals to pitchers in lieu of using finger signs, Jeff writes.

• The new system, developed by a company called PitchCom, will be introduced next week in Low-A West, an eight-team division. Its use will be "optional but strongly encouraged," per ESPN.
• Why it matters: Doing away with complex finger signs — and the mound visits they can cause — should speed up the game, while also preventing future sign-stealing scandals.

The big picture: This is one of many experiments being conducted in the minors. Others include larger bases (more steals), banned shifts (more hits), and even home run swing-offs (to replace extra innings).

How it works: The pitcher and catcher will each wear receivers in the padding of their hat/helmet, and the catcher will also wear a transmitter on his wristband.

• The transmitter has nine buttons, which the catcher will use to signal pitch type and location.
• The receivers — using safety-tested, bone-conduction technology — will relay the pitch selection using a prerecorded voice.

Food for thought ... They're still just early-stage tests, but between electronic signals and robot umpires, technology is encroaching on America's (very traditional) pastime to a startling degree. Consider this:

• The pitcher throws a fastball — called electronically — toward home plate, where a computer is relaying balls and strikes to the umpire.
• The batter swings and gets called out at first on a bang-bang play ... that his manager immediately challenges via instant replay.

88 years ago today, Joe DiMaggio's other hitting streak came to an end after 61 games — the second-longest in minor league history.

Why it matters: Eight years later, DiMaggio compiled his famous 56-game hitting streak with the Yankees. But without his minor league streak, he may never have become the player that he did.

"Baseball didn't really get into my blood until I knocked off that hitting streak [in the minors]. Getting a daily hit became more important to me than eating, drinking or sleeping."

The backdrop: At 18, this was DiMaggio's first full professional season, playing with the Pacific Coast League's San Francisco Seals.

• He'd joined the team one year prior after his older brother Vince, a rookie outfielder on the Seals, said his brother Joe could fill in for their recently departed shortstop.
• His bat was spectacular, but a shortstop he was not, so he soon switched to outfield. There, his speed and arm were unmistakable assets, and a baseball legend was born.

The aftermath: In 1934, despite a worrisome knee injury, the Yankees purchased DiMaggio's contract.

• After one more stellar season with the Seals (.398 BA, 34 HR, MVP), he debuted in the Bronx in 1936 and proceeded to make the All-Star team in all 13 seasons, winning three MVPs and nine World Series.

This week, we're counting down the five best Olympics movies of all time.

Foxcatcher (2014) tells the true story of millionaire John du Pont recruiting two gold medal-winning brothers, Mark and David Schultz, to move to his estate and help form a wrestling team for the 1988 Olympics.

• Runtime: 2 hours, 14 minutes
• In one word: Chilling
• Watch: Trailer

What makes it great: While Olympics coverage focuses on feel-good stories and celebrates human achievement, "Foxcatcher" serves as a reminder of the darkness that can simmer beneath the surface.

• The three stars — Steve Carell (du Pont), Channing Tatum (Mark Schultz) and Mark Ruffalo (David Schultz) — deliver incredible performances. Especially Carell, who couldn't be creepier.
