43 Adam Warren RP

Warren (back) will throw off the mound in Tampa on Monday, Bryan Hoch of MLB.com reports.

This will mark the first time Warren gets back on the mound since going down with a right back strain following an outing against Toronto on April 20. He recently tossed the ball around off flat ground earlier this week and remains on track for a return to the majors when the Yankees get back from their three-city road trip May 25.

Yankees general manager Brian Cashman said that Warren (back) has resumed throwing off flat ground, Mike Mazzeo of the New York Daily News reports.

While the fact that Warren is throwing again amounts to progress in his recovery from a back strain, Cashman noted that the right-hander is at least 10 days away from returning from the disabled list. Before an activation is considered, Warren will need to resume throwing bullpen sessions, then face hitters in live batting practice or a simulated game before beginning what would likely be a brief minor-league rehab assignment. Don't expect Warren to be ready to rejoin the Yankees bullpen until the second half of May at the earliest.

Warren (back) will spend more than the minimum 10 days on the disabled list, Coley Harvey of ESPN.com reports.

Warren was placed on the 10-day DL on Saturday with a right back strain and is expected to be shut down for at least those 10 days. It's still considered to be a mild strain, but the Yankees are expressing caution in the season's early going. The 30-year-old's status should be updated as the start of May approaches.

Warren was put on the 10-day DL due to a right back strain prior to Saturday's game against Toronto.

In a corresponding move, the club recalled Jonathan Holder from Triple-A Scranton/Wilkes-Barre. Warren pitched against the Blue Jays on Friday, going 2.2 innings and allowing one earned run off two hits and one walk while striking out three. He appears to have suffered the injury during that outing, which will cause him to spend some time on the shelf. The 30-year-old will be eligible to return against the Astros on May 1.

Warren (ankle) is available out of the bullpen for Wednesday's game against Tampa Bay, Bryan Hoch of MLB.com reports.

Though he wasn't inserted into the contest, manager Aaron Boone added that Warren was available during Tuesday's game as well. The 30-year-old reliever shouldn't face any limitations after getting struck in the ankle by a comebacker on Opening Day.
