CHICAGO — The Los Angeles Dodgers’ trade for Tarik Skubal did little to dispel the notion that the back-to-back World Series champions are baseball’s premier villain. That sentiment was clear on Tuesday at Wrigley Field, where a plane circled above displaying a banner that read: “THE DODGERS RUINED BASEBALL.”The message, which carried the logo of a sports betting company, was displayed upside down. It wasn’t immediately clear whether that was part of the bit or a simple case of human error. No matter why it was displayed incorrectly, the words amplified a popular post-trade deadline talking point. The banner fluttered in the sky ahead of Tuesday’s Dodgers-Cubs game, Skubal’s first start for Los Angeles.The Skubal trade reignited a familiar conversation — that the Dodgers will be the root cause of MLB’s anticipated lockout this winter.Skubal, who was booed in Chicago as he walked to the bullpen to warm up, had established his rebuttal a day earlier.“I don’t really sympathize with people that blame the Dodgers for anything they’ve done,” the two-time Cy Young Award winner said Monday. “They’ve developed a really good organization.”The Dodgers have the top payroll in baseball, with an estimated luxury tax figure of $430.9 million, according to Cot’s Contracts. Skubal is simply the latest in a string of superstars to join the club. In the offseason, after beating the Toronto Blue Jays in the World Series, the Dodgers splurged on outfielder Kyle Tucker (four years, $240 million) and closer Edwin Díaz (three years, $69 million).They are heavy favorites to win again, with the highest odds of winning the World Series, according to FanGraphs projections (26.9 percent).Do they feel they’re ruining the sport?
