ARLINGTON -- Outfielder Hunter Pence is in position to be activated off the injured list on Tuesday when the Rangers play the D-backs at Globe Life Park.

The Rangers have not made a final decision yet. Pence will be evaluated by their medical staff on Tuesday afternoon to make sure he is ready. But unless something unexpected comes up, Pence is expected to be activated for Tuesday’s game.

He was 2-for-4 in his fourth medical rehab game with Double-A Frisco on Sunday night and is off on Monday. The Rangers could use his right-handed bat since the D-backs are scheduled to start left-handers Alex Young and Robbie Ray during the two-game series.

Other injury updates
• Left-hander Taylor Hearn threw a 20-pitch bullpen session on Saturday at the Rangers complex in Surprise, Ariz., and he has two more scheduled for this week. After that, he could start pitching in games again. He has been sidelined with a sprained ligament in his left elbow since making his Major League debut on April 25 against the Mariners.

• Left-hander Yohander Mendez, who has been sidelined since Spring Training with a strained left elbow, has been throwing in the bullpen in Arizona. He's scheduled to start throwing live batting practice this week.
