Kendrick (hamstring) joined the Nationals' taxi squad during the team's recently completed road trip and continues to make progress in his rehab, Mark Zuckerman of MASNSports.com reports. "We're going to be careful with him," Martinez said of Kendrick. "He's had these hamstring issues before. We've talked about this: We don't want him to blow out now. But we told him as soon as [he's] ready and we deem that [he] can play, we'll activate him and see if we can get him back this week."

The Nationals placed Kendrick on the 10-day injured list Wednesday with a left hamstring strain, Jesse Dougherty of The Washington Post reports.

Kendrick will sit Tuesday against Tampa Bay.

Kendrick isn't in Monday's lineup against the Rays.
