Rookie outfielder J.P. Martínez, who was called up to the major leagues less than a week ago, is already making a strong impression on the Texas Rangers. Despite the team’s loss to Los Angeles on Wednesday, Martínez managed one of only three hits for the Rangers that night. Manager Bruce Bochy praised Martínez’s confidence and competitiveness, leading to speculation that he could potentially take playing time away from starting center fielder Leody Taveras. Since his callup, Martínez has gone 8 for 19 (.421) with two walks and has shown smart aggressiveness on basepaths.
