Houston Astros shortstop Carlos Correa says he is in pain: Every swing and miss hurts his aching back, and on the bad days it can even be uncomfortable to walk.

Correa often puts on a brave face but he tells The Associated Press he is hurting as the Astros prepare to leave for Boston and the best-of-seven AL Championship Series that begins on Saturday.

Correa returned from a six-week stint on the disabled list on Aug. 10 and declared that he was better. But he has struggled to regain his top form. He hit just .180 in the second half of the season and managed a single hit in an ALDS, looking nothing like the player who made the All-Star team last season and was the 2015 rookie of the year.

He says it’s been difficult to feel comfortable at the plate and he is not swinging as hard or as quick as he wants to.
