Twins outfielder Jordan Luplow recalls a game at Progressive Field in which he was approached by a fan in right field.

A man had fallen over the wall and, after picking himself off the warning track, started walking toward Luplow.

“It was a little scary for a second,” he said.

“You know when you see a real drunk guy and he’s just kinda staring through you? Like he’s looking at you but he’s looking through you?” Luplow said. “And he was big, probably like 6-6, 300 pounds. And I’m like, ‘Dude, this guy’s coming right at me.’ ”

Fortunately, the fan veered left and off the field, but for a few seconds, Luplow started thinking about how he would defend himself from a man he estimated to be about 6-foot-6 and 300 pounds.

He was reminded of the incident after a pair of fans approached Atlanta’s Ronald Acuña Jr., apparently looking for selfies with the outfielder, during the Braves’ 14-4 victory at Colorado on Monday.

“Unacceptable,” Luplow said.

Every once in a while, a fan runs onto the field during a major league baseball game and runs around before being tackled by mostly outmatched security. But you rarely see them get that close to a player, let alone knocked down.

“That shouldn’t happen,” Twins manager Rocco Baldelli said.

Acuña was tripped by one of the fans as security worked to subdue them and fell on his back.

“What if he rolls an ankle, or his knee gets caught? Then he’s out for the season or something,” Luplow said. “That’s not something we want, and it’s not something the fans should want.”

In light of the incident, and another involving a discharged handgun at Guaranteed Rate Field in Chicago, a spokesperson for the Major League Baseball Players Association told ESPN the union will review the safety and security protocols of all teams and stadiums. An email to MLB on Wednesday was not immediately answered.

“I’m sure Major League Baseball is going to take that very seriously, and I hope if there’s anything that can be done to ensure that doesn’t happen again any time soon, it happens,” Baldelli said.

Waiver Wire-Palooza

Thursday marks the final day big league teams can acquire a player and still add him to the postseason roster, and since the trade deadline passed on Aug. 1, that means a waiver wire pickup.

While the Twins have some of the best pitching in baseball, and are close to getting several players back from injury absences — among them Byron Buxton and Alex Kirilloff — they still will be looking hard for anyone who might be able to help them in the playoffs.

Big names available include such as Angels starter Lucas Giolito and White Sox starter Mike Clevinger are not likely targets. The Twins have a surfeit of starters, plus Giolito knocked out half of Kyle Farmer’s teeth in April, and Clevinger has a $12 million option on his contract for 2024 that includes a $4 million buyout. But the Twins would probably be interested in proven bullpen arm and possibly a right-handed bat.

The deadline to add a postseason-eligible player is officially midnight on Thursday. The order will be determined by record and, in the case of ties, a series of other factors such as last year’s record.

On Friday, active rosters expand from 26 to 28 players. Barring a waiver pickup, which requires the player to be placed on the active roster, the Twins will likely add a reliever from St. Paul and take utility man Willi Castro (oblique) off the injured list.
