NEW YORK — Jazz Chisholm Jr. quietly stood at his locker, packing his duffel bag with equipment for the New York Yankees’ six-game trip to Toronto and Baltimore. He looked quizzically at the bats he’d pack, hoping one of them might deliver the results he’s been searching for since the season began.Chisholm is usually a man of many words. Few in the Yankees’ clubhouse have as bright a personality as the second baseman, but there was nothing to say Thursday afternoon after another dismal performance. He finished 0-for-4 with three strikeouts in a 1-0 loss to the Seattle Mariners. He swung at seven pitches and whiffed on four. The other three swings resulted in two foul balls and a weak groundball to Mariners first baseman Josh Naylor.It’s been a season from hell for Chisholm at the plate, and he is at a loss for answers to address his lack of success.“If I knew, I would already have fixed the problem,” Chisholm told The Athletic. “Even when I think I’m getting going hitting, it’s still an out. I’m still hitting it right at someone. I can hit it 107 (mph) and still hit it right at someone.”His 92 wRC+ makes Chisholm one of the 20 worst qualified hitters across MLB. He picked the wrong year to have a career-worst season at the plate. He’ll be a free agent after this season, and his performance might cost him millions of guaranteed dollars.Do trade deadline deals lead to World Series rings?Joe CrisalliChisholm came into the season with the highest of expectations, proclaiming he would become the second player in MLB history, joining Los Angeles Dodgers superstar Shohei Ohtani, to finish with at least 50 home runs and 50 stolen bases. Although he won’t reach those numbers, he has an opportunity to post a 20-40 season, which would still be eye-popping. The raw numbers do not tell the story of Chisholm’s season, though. Outside of the home runs (17) and stolen bases (31), he’s mostly been inefficient.His on-base percentage has dipped below .300. His strikeout percentage ranks in the bottom 10 among all hitters. He has the fifth-worst percentage in making contact on pitches thrown inside the strike zone. No qualified hitter has provided less value against curveballs than Chisholm, according to FanGraphs. Alarmingly, he has swung and missed at nearly 40 percent of all breaking pitches this season.And yet, he thinks he’s been worse than what the numbers say.“I feel like I have a 40 percent whiff rate on every pitch right now,” Chisholm said. “I don’t know why. I swing up. I swing down. I’ve tried to fix it a couple of different ways. When I fix it, it’s still unlucky.”
