Texas Rangers catcher Luis Martinez marveled at his lucky break on Tuesday. Just as Japanese pitching star Yu Darvish had completed his warm-up tosses, Martinez was ready to catch another bullpen session. So the 26-year-old Martinez, who was traded to the Rangers in January from San Diego for a minor league reliever, caught 30 pitches thrown from Darvish's right arm. It was the first workout for Darvish in a Rangers uniform at spring training.
