Left fielder David Murphy’s trying April continued Sunday as he went hitless in four at-bats during the Rangers’ 5-0 loss to Minnesota at Target Field. Murphy opened the seven-game trip with a two-hit game in a win at the Los Angeles Angels. He went 3-for-24 on the duration of the trip, dropping his average to .176, 10th-lowest among American League qualifiers. His average has been below .200 since the second day of the season. “I’ve had days when I felt good and days when I’ve felt terrible,” said Murphy, hitless in his last 10 at-bats. “Today, I felt great and had nothing to show for it. It’s been a frustrating time, but there’s a lot of season left. I’m going to keep battling.” Murphy is coming off a season in which he hit .304, his highest for a season in which he qualified for the batting title. Murphy has said that his pending free agency is not weighing on him. This is the first season in which Murphy has received extensive playing time against left-handed pitching. He is having more trouble with right-handers. Murphy has only four hits in his last 32 at-bats against right-handers. “We need to get Murph going,” manager Ron Washington said.
