May will open the season at Double-A Tulsa, J.P. Hoornstra of the Los Angeles Daily News reports.
May's strong showing in six Double-A starts in 2018 along with an excellent spring fueled speculation he might make the jump to Triple-A Oklahoma City to begin the campaign. Instead, he'll be booked for a return trip to Tulsa, but he shouldn't remain there for long if he's able to avoid the control issues that occasionally cropped up in his brief stint with the affiliate a season ago.
