Jordan Walden (back) will return to Grapefruit League action on Wednesday. Walden was cleared after another pain-free live batting practice session on Monday. He's been limited to one spring appearance due to a bulging disc in his back, but he should be OK for Opening Day as long as he can avoid a setback. If Walden isn't ready for the opener, Anthony Varvaro is expected to take his spot in the bullpen.
