Ponce de Leon signed a minor-league contract with the Nationals on Friday, Jesse Dougherty of The Washington Post reports.
Ponce de Leon has spent time on minor-league deals with the Angels and Mariners this year, and he'll have a chance to carve out a role in the Nationals' system now that the All-Star break is over. The right-hander made 16 starts at Triple-A Tacoma earlier in the year and posted a 7.95 ERA and 1.67 WHIP in 71.1 innings.
