​After dropping a heartbreaker against the Chicago Cubs on Thursday afternoon, the Toronto Blue Jays enter Friday’s series opener against the Philadelphia Phillies on the wrong end of team history.As noted by @StatsCentre on social media, the Jays have a .376 slugging percentage as a team, which is on track to be the fifth-lowest slugging percentage in team history.Only the 1981, 1978, 1979 and 1977 teams have been worse. Each of those teams were in the first five years of the franchise’s existence, showing just how long it’s been since the Blue Jays were this anemic offensively.What has led to this? Well, injuries certainly haven’t helped. And while the injuries can’t be blamed for every single struggle of any team, the Jays have missed several players they were counting on to provide pop in the order this season:1) Addison Barger has missed almost the whole season because of ankle and elbow issues. He’s undergone elbow surgery and is expected to be ready for spring training. He was a breakout player for the 2025 Blue Jays, excelling in the playoffs as he hit nearly .400. He played only nine games this season.2) Anthony Santander, signed to a five-year deal before the 2025 season, has missed the entire season because of labrum surgery that he underwent in the offseason. He was signed to help lengthen the middle of the order, and he just hasn’t been able to do it.3) At various points of the year, Alejandro Kirk, George Springer, and Jesus Sanchez have all been on the injured list, sapping at the production.Toronto Blue Jays first baseman Vladimir Guerrero Jr. (27) bats during the third inning against the Houston Astros at Daikin Park. Troy Taormina-Imagn Images4) Vladimir Guerrero Jr., a perennial All-Star, is hitting just .259 with only six home runs. He has yet to hit a home run inside the Rogers Centre.5) The Blue Jays let Bo Bichette leave in free agency, as he signed a deal with the New York Mets. But in fairness, his replacement, Kazuma Okamoto, has played very well and is in contention for the American League Rookie of the Year Award. He was signed to a four-year deal worth $60 million in the offseason. Of noteThe Jays enter Friday’s series with the Philadelphia Phillies at 54-62 and in last place in the American League East. That said, they are still only 3.5 games back in the American League wild card chase.
