Five thoughts from the second week of the baseball season:

1. Watch your words

It’s simple, really.

Major League Baseball needs to suspend Diamondbacks manager Torey Lovullo and send a message that his punkish behavior is not acceptable.

Lovullo apologized for calling Cardinals catcher Yadier Molina an unprintable name during an argument with umpire Tim Timmons on Sunday afternoon, but you have to wonder if he would’ve admitted it had it not been caught on camera.

The words enraged Molina, and rightfully so, causing him to go at Lovullo before being separated.

“I have the utmost respect for Molina,” Lovullo said afterward. “I used a poor choice of words and he took offense to it. I wish I could take back what I said.”

Lovullo maintained he was not saying anything “to” Molina but admitted he was “referencing him in a wrong way.”

Whatever he meant, Lovullo needs to be disciplined immediately.

Managers are allowed to get overheated and put on crazy displays on the field. It’s a part of the game I miss since replay challenges came into existence and drastically reduced the number of confrontations between managers and umpires.

But a manager can’t call an opposing player an obscene name without expecting a punch in the mouth, a fine and a suspension.

“He called me (expletive) twice,” Molina told the St. Louis Post-Dispatch. “If you’re going to call (that) to a guy, you have got to be ready to fight. And he pointed at me too. That’s unprofessional. Hopefully we can meet face to face and see if he has some (fortitude) and can tell me (why) right to my face.”

Lovullo was lucky Molina didn’t get to him. The brawl could have gotten ugly and players could have been injured.

A fine isn’t enough. Give Lovullo a short suspension along with the fine, and assure fans baseball won’t tolerate that kind of disrespect.

2. Me TV

Speaking of profane outbursts, Cubs catcher Willson Contreras also was caught on camera Sunday mouthing a profanity a few times while shouting to an unnamed Brewers player from third base.

It would be wise for one of the many Cubs executives to inform Contreras that he’s always on camera and that his behavior was inappropriate. He is one of the best young catchers in the game, but if Contreras continues at this pace, he’ll be the most disliked catcher in baseball since A.J. Pierzynski in his heyday.

Who knows? Maybe that’s the image he’s going for.

If so, good luck.

3. Sho Time

Shohei Ohtani may be the most refreshing thing to hit baseball since Mark Fidrych’s rookie season in Detroit.

In the last week, the Angels rookie hit three home runs as a designated hitter, got two wins and struck out 18 in his first two starts and took a perfect game into the seventh inning Sunday against the A’s.

He’s hitting .389 with a 2.08 ERA and could be the American League starter in the All-Star Game, if he’s not voted in as DH. Ohtani became the first player with three homers and two wins in the first 10 games since the Washington Senators’ Jim Shaw in 1919.

More importantly, the Angels drew a crowd of 44,742 on Sunday, most of whom came out to see Ohtani.

“I’m happy I was able to respond to their expectations, however little,” Ohtani said in Japanese. “Every time I’d like to perform in a way that won’t betray their expectations.”

“Sho Time” has become an official cultural phenomenon in La-La Land, and the Angels are threatening to overtake the underachieving Dodgers in media coverage in the early going.

It seems like eons ago, during his spring training struggles in Tempe, Ariz., that people were wondering if he was being overhyped.

4. World War III (cont.)

Warning: The Red Sox and Yankees resume their rivalry Tuesday in Boston. Bring a comfy pillow.

“I used to get calls from Commissioner (Bud) Selig, ‘Why do the Yankees and Red Sox play such long games?’ ” Chief Baseball Officer Joe Torre said. “It was all strategy. I said, ‘Commissioner, nobody left the ballpark.’ ”

Selig was right.

“We did play some long ballgames,” Torre said. “It was like World War III all the time.”

The continuation of World War III will likely begin with the traditional highlights of Pedro Martinez throwing down Don Zimmer and Bucky Dent’s home run followed by the sight of Giancarlo Stanton in Fenway Park wearing the classic Yankees road uniform.

Familiar skippers Joe Girardi and John Farrell are gone, replaced by Aaron Boone and Alex Cora. Chris Sale is now in the Martinez role as the most dominant starter in the AL. Stanton is the new-age Reggie Jackson and already has two five-strikeout games. The Green Monster is still the Green Monster.

The names and faces may have changed, but the media overload remains. Rest assured the series will be overhyped and the games will last longer than a day at the DMV. ESPN will carry Tuesday’s opener pitting Sale against Luis Severino. MLB Network will carry the next two games, including David Price versus Masahiro Tanaka on Wednesday.
