Texas Rangers right-hander Max Scherzer struck out five while retiring 12 of the 14 batters he faced Sunday in his long-delayed second rehab start for Triple-A Round Rock since offseason surgery for a herniated disk in his lower back. Scherzer threw four scoreless innings, then exited the game after an eight-pitch walk that opened the fifth against Oklahoma City, an affiliate of the Los Angeles Dodgers. Scherzer's first rehab start was 52 pitches for Round Rock on April 24, but the second start was pushed back because of right thumb soreness that team doctors later identified as a nerve issue that extended to his right triceps.
