Texas Rangers right-hander Yu Darvish said he may throw an extra bullpen session after getting two extra days off this week to prepare for his next start. Darvish showed off the finger that had been bothering him, and it appeared there was a tiny callous there where the torn skin had been.

Darvish’s bigger issue is his command. He allowed Seattle three runs in the first inning Friday. It appeared Darvish lost the feel for his cutter while dealing with the finger issue. He threw 50 cutters in his season debut when he came within an out of a perfect game. Five days later, it dropped to 23. He threw just 13 against Seattle. Darvish said he needed to make an adjustment but declined to elaborate.

Asked over the weekend if the issue was with his cutter, Darvish, through an interpreter, said: “Leave it mystical. I don’t want to say.”

Briefly: Triple-A Round Rock LHP Brad Mills was named the Pacific Coast League Pitcher of the Week after allowing just one earned run in 13 innings while winning his first two starts. Mills was claimed off waivers from the Los Angeles Angels at the end of spring, then cleared waivers with the Rangers. If the Rangers were to need more rotation depth, he might be a top option. … The Rangers have not received an RBI from either Craig Gentry or Leonys Martin. Texas began the week as the only team in the majors not to have an RBI from the center field position. The duo is a combined 0-for-9 with runners in scoring position. The duo, however, has scored 10 runs, tied for the fifth most from that position in the majors. … LHP Joe Ortiz has not allowed a left-handed hitter to reach in 11 plate appearances this season, the most by any major league lefty.
