Jordan Walden, looking very much like a young John Lackey, delivered two impressive innings in his Cactus League debut. The 6-foot-5 flamethrower from Texas ended both innings with strikeouts, leaving runners stranded, and finished with three K’s.

The Athletics collected a pair of hits — Eric Chavez’s single through the middle in the first, Chris Carter’s opposite-field double leading off the second — but Walden buckled down when he needed outs. He caught dangerous Jack Cust looking at a third strike to end the first and Rob Bowen went down swinging to finish the second.

With a pitcher as young as Walden, who turned 21 in November, his response to adversity often determines how swiftly he advances through the system. Walden’s stuff is premium: 95-96 mph heat that he holds into the sixth and seventh innings, complemented by developing off-speed stuff. With one out and Carter on third, Walden got Cliff Pennington to roll over on a grounder to Kendry Morales at first, and he shot down Carter at the plate. That was a location pitch, not a bullet, that got Walden out of trouble — a very good sign in his development.

Walden worked at two Class A levels last season, striking  out 141 hitters in 156 1/3 innings at Cedar Rapids and Rancho Cucamonga. This guy could be on the fast track to Anaheim if he continues his development this season.
