Jay Bruce, who was placed on the 10-day DL earlier this week while dealing with a butt/back issue and plantar fasciitis in his left foot, said Friday that he has also been dealing with a hip issue since March -- and that it has probably negatively affected his play.
Bruce said there is no timetable for his return.
"The injury has not been apparent for that long," Mets GM Sandy Alderson said. "It really hasn't been about playing him through injury."
The 31-year-old Bruce, who signed a three-year deal worth $39 million during the offseason, has not hit a home run since May 7, and has just one extra-base hit in June.
Overall, Bruce is hitting .212/.292/.321 with three HR and 12 doubles in 62 games. He is on pace to finish the season with seven home runs -- a year after hitting 36. His .321 slugging percentage is one of the lowest in all of baseball.
Bruce's line drive percentage is 23.3 percent, which is the second-best of his career, so he has been hitting the ball hard. And his fly ball rate of 45.4 percent is around his career rate of 42.5. But when he does hit the ball in the air, it's usually not going far, which can be seen when looking at his home run to fly ball rate.
Bruce's career HR/FB rate is 16.4 percent. It was 19.4 percent in 2016 and 18.5 percent in 2017. This season, it's an almost impossibly low 4.1 percent. And now we likely know why.
