Cubs' Kyle Tucker secretly played through concerning injury during slump

Cubs star Kyle Tucker suffered a hairline fracture in his right hand back in June, reports Jesse Rogers of ESPN. Tucker jammed his right hand diving into second base on a stolen base attempt in a game against the Reds on June 1. Cubs skipper Craig Counsell publicly confirmed the June fracture but says Tucker is now healthy, via Rogers.

Initial X-rays came back negative. However, Rogers writes that follow-up testing revealed a small fracture at the top of his hand between his ring finger and pinky. The Cubs did not announce the diagnosis at the time, and Tucker has not spent any time on the injured list. The four-time All-Star preferred to play through the injury.

In retrospect, it’s fair to question whether that was prudent. Tucker had been one of the best hitters in MLB for the season’s first two months. He owned a .284/.395/.524 slash with 12 homers across 269 plate appearances through June 1. Since then, he’s batting .236/.352/.368 in almost the exact same amount of playing time. Tucker has connected on six longballs over the past two-and-a-half months.

While the injury certainly seems to be having an impact, it’s worth noting that Tucker actually continued to play well in the immediate aftermath. He hit .311 with five homers in June. It wasn’t until July that things went completely off the rails. He’s batting .189/.325/.235 with one homer in his past 38 games.

Tucker’s plate discipline remains strong — he has actually walked more often than he has struck out during that stretch — but his power has completely evaporated. His rate of hard contact (batted balls with an exit velocity of at least 95 mph) was between 44-50% in each of the first two months. It remained solid at 42.9% in June but has plummeted below 30% in each of the past two months.

That kind of play from a hitter of Tucker’s caliber has naturally led to speculation about his health. Pat Murphy, manager of the Milwaukee team that is playing the Cubs this week, opined that the outfielder was playing through an injury. “I think Tucker’s hurt. I don’t have any information, but Tucker’s not the same,” Murphy said on 670 The Score.

Tucker himself has maintained that he’s physically OK. However, president of baseball operations Jed Hoyer conceded to Rogers “that when you look at his numbers, it’s had an impact on him, for sure. That’s the nature sometimes of these small injuries. They can do that.” Counsell has kept Tucker out of the lineup for the past three games — two days, including a doubleheader on Tuesday. Chicago won all three games over the MLB-best Brewers with Owen Caissie playing right field. Counsell hasn’t committed to Tucker’s status for Thursday's series finale.

The Cubs remain six games back of Milwaukee in the NL Central. They’re comfortably in wild-card position, which gives them the flexibility to mix in more off days for Tucker if necessary. They’ll need to find a way to get him back to being productive if they hope to make a deep playoff run. The injury and slump obviously come at an inopportune time for Tucker personally, as he’s a couple of months from free agency. He’s the clear No. 1 player in the class and generally expected to command $400M+ as he enters his age-29 season.
