SCOTTSDALE, Ariz. -- D-backs center fielder A.J. Pollock left Sunday's 12-4 loss to the Giants as a precaution after he experienced left groin tightness in the first inning.
Pollock homered off Giants lefty Matt Moore to lead off the game and did not make a play in the field before he was pulled. D-backs manager Torey Lovullo relayed that Pollock said he felt something rounding the bases on the homer, as he twisted his body awkwardly trying to follow the flight of the ball and pick up the umpire for a signal as to whether the ball cleared the left-center-field fence.
"I don't think it's anything that's going to linger," Lovullo said. "We just want to be safe at this point. ... With everything he's been through to get to this point, we didn't want to risk anything."
Pollock missed most of last spring with an elbow injury that ultimately needed surgery and caused him to miss the season's first five months. He returned for 12 games before a groin injury, also on the left side, in September ended his season.
Worth noting
• Shelby Miller gave up three runs on four hits and struck out three in four innings in a Minor League intrasquad game Sunday morning. He did not walk a batter in his 60-pitch outing.
"It looked like he was commanding the ball real, real well," Lovullo said.
Miller is expected to next pitch Friday against the Mariners in a split-squad game.
• With the D-backs off Monday, staff ace Zack Greinke will pitch in a morning Minor League intrasquad game at Salt River Fields. Braden Shipley, Zack Godley and Keyvius Sampson also will pitch in that game.
• Jeff Mathis, known as a defensive catcher, had two hits in two at-bats Sunday and is hitting .500 (6-for-12) this spring.
• D-backs pitchers will begin to bat next time through the rotation, beginning Friday.
• Yasmany Tomas, 0-for-17 this spring and out with a sore back since March 6, is penciled into the lineup Tuesday, Lovullo said. "But we'll see how he feels when he gets to the park that morning," the manager added.
