Worth noting

• Lefty Drew Pomeranz, acquired by the A's from the Rockies for Brett Anderson, made his spring debut on Saturday against the Rangers and allowed one hit and struck out two in an inning of work.

"Big arm, no question about it," said Melvin. "There's a lot of upside there."

• The A's continue to be encouraged by reliever Fernando Rodriguez's progress. The right-hander, who underwent Tommy John surgery a year ago, threw 40 pitches to hitters on Saturday and "looked real good," said Melvin.

It's still not clear whether Rodriguez will be ready in time to pitch in games this spring.

John Jaso, hit by a pitch above his right elbow in Wednesday's Cactus League opener, returned to play on Saturday in the sixth inning, getting an at-bat at designated hitter. He will start at catcher in Sunday's game against the Angels.
