A day after Johan Santana's disastrous return from the disabled list — just four outs, eight runs and countless concerns and questions about his health — the Mets said the left-hander is physically fine, and they have no plans to shut him down again, at least not at the moment.

"I'm planning on certainly in five days seeing him back out there,'' manager Terry Collins said of Santana, who is expected to make his next start Friday in Washington.

In his first start since returning from the disabled list, the 33-year-old lasted just 1 ¹/3 innings (tied for the shortest stint of his career), but both Collins and catcher Josh Thole insisted it was more about rust than health, and that with an extra day of rest (the Mets are off today) Santana will be fine against the Nationals.
