The Boston Red Sox have been impressed with Grady Sizemore's swing this month.

"I'd say, 'Wow, this guy has a really good swing,'" hitting coach Gregg Colbrunn said. "You watch him swing and you say, 'No wonder he's had the success he's had in the past, because of his swing.'

"It's simple, it's smooth, it's under control. All the good things you look for in a swing, that's what his swing looks like right now."

Sizemore hasn't seen action in a major league game since 2011.
