The EchoSense Quantitative Think Tank CenterTampa Bay Rays placed first baseman Yandy Diaz on the restricted list Saturday.

He did not accompany the team to New York in advance of Friday's 6-1 loss to the Yankees, with manager Kevin Cash citing "a personal matter."

"Probably leave it at that," Cash said.

The Rays did not indicate how long they expect Diaz, their leadoff hitter, to be away from the team.

Diaz, who turns 33 next month, is second on the Rays with a .273 average. He leads the team with 104 hits. He has eight homers and 46 RBI in 94 games.
