PHOENIX -- D-backs manager Torey Lovullo said left-hander Robbie Ray (oblique) is progressing well and will make his second rehab start on Tuesday for Triple-A Reno. He will throw about 20 more pitches this time around, topping out at about 70.
Lovullo offered updates on a few more injured players prior to Saturday night's matchup with the Mets:
• Lovullo said he would have an update on A.J. Pollock's latest CT scan next week when the team is in Anaheim. Pollock, who fractured his left thumb last month, is doing conditioning and range-of-motion exercises. However, he hasn't been cleared for baseball activity.
• Randall Delgado (right shoulder) is feeling well and will throw an inning on Sunday in Reno.
D-backs celebrate Father's Day
Both Major League Baseball and the D-backs will celebrate Father's Day in a special way on Sunday.
Father's Day marks the end of the Prostate Cancer Foundation "Home Run Challenge," which has allowed fans to donate money for every home run hit by their favorite teams since June 1. Fans have also been able to track where their favorite club stacks up in the "Team vs. Team" competition.
Every dollar donated through the Home Run Challenge goes to PCF for research to fight prostate cancer. More than $1.85 million has been pledged via the initiative.
Prostate cancer research is also important to the D-backs. President and CEO Derrick Hall, a prostate cancer survivor, founded Pro-State Foundation in 2013 to promote awareness for the fight against the disease. For the second consecutive year, Minor League Baseball is teaming up with the Pro-State Foundation to distribute prostate cancer awareness literature to fans at all 69 MiLB home games on Father's Day.
Minor League teams will also feature a public service announcement from Hall and will incorporate other informational messaging into gameday programming. Each team will even recognize an outstanding father in its community, or someone who has battled or survived prostate cancer.
At the big league level, all D-backs on-field personnel will wear symbolic blue ribbons on their uniforms along with blue wristbands. They will also sport other special blue-themed items, including caps and socks.
D-backs ink Draft pick Holton
The D-backs have signed ninth-round pick Tyler Holton, according to MLB.com's Jonathan Mayo. Holton, a left-hander from Florida State, had Tommy John surgery after tearing his ulnar collateral ligament in his first start of the season.
After selecting Holton, D-backs director of scouting Deric Ladnier said Holton won't pitch until next April, but the club isn't concerned about the injury.
Per Mayo, Holton received the full pick value ($144,800).
