Darvish, Martin Perez, Sam Dyson and Alex Claudio threw Monday. They are the scheduled pitchers for the first Cactus League game Saturday against the Royals with Darvish getting the start. Darvish and Perez are down for approximately two innings and 30 pitches.
"I'm going to be with him every game during the regular season, so it's important to get a feel for him," Lucroy said. "The key with him is to find how he is feeling from day to day. One day he may feel one pitch is better than the other, four days later, he might feel better with the other. It's all about communicating with him."
The most important pitch right now seems to be the split-fingered fastball, which Darvish stopped throwing after Tommy John elbow reconstruction surgery, but he wants to bring it back into his repertoire. He got swing-and-miss and ground balls on it Monday.
"I feel comfortable with the split-finger," Darvish said.
