Patrick Wisdom’s stellar rookie campaign came to an end Wednesday, less than a week before the season ends, after being placed on the injured list without a designation.

David Ross and the Cubs didn’t reveal the injury, but he was not on placed the 10-day injured list nor on the 60-day IL. Because he was just placed on the injured list, the Cubs didn’t have to make room on the 40-man roster for the corresponding move of selecting the contract of Trent Giambrone.

“He just went on the injured list,” Ross said of the move. “With him, it’s the end of his season.”

Wisdom had been dealing with a wrist injury, but Ross specified that this move wasn’t related to that and that the issue arose Wednesday. Some Cubs players were wearing masks pregame at PNC Park.

“I think we’re following all MLB protocols and trying to do what we can to make sure everybody’s healthy and safe that steps foot on that field,” Ross said. “All we can do is continue to follow MLB protocols and try to set up everybody to be as safe as possible and play major league baseball.”

It ends his season on a bit of a sour note, after he crushed 28 home runs, a new franchise record for a Cubs rookie. He had an .823 OPS with 61 RBI and a 2.3 WAR in 106 games this season.

The ability to hit for power didn’t come without a high strikeout rate, as Wisdom struck out at a 40.8% clip, but Ross emphasized that if he were to try to cut that number down, it might cost Wisdom some of his aggressiveness at the plate that allowed him to slug 30 homers.

“I think that’s what I would say stood out to me,” Ross said. “He came here and stuck to who he was.”

That also meant working at his craft. When he came up, the consensus on him was that he was a plus-offensive player but wasn’t that as a defender at the hot corner. He worked on his defensive reps and showed he could play strong third base. Wisdom posted 6 outs above average at third base, fifth best in baseball behind Matt Chapman, Ke’Bryan Hayes, Ryan McMahon and Nolan Arenado.

He showed versatility, too, playing first base, left field and right field.

“Being able to move him around is a luxury for us as guys have kinda gone up and down or gotten hurt,” Ross said.

Wisdom will go into the offseason with a positive first season and knowing, for the first time in his career, that he’s likely to be on a big-league roster to start the season and that his skillset plays on a major league team.

“I think he’s made the most of his opportunity and he should be really proud going into his offseason,” Ross said. “I think there’s a space for that type of player.”
