LOS ANGELES -- D-backs pitcher Brandon Webb struck out a pair of batters in his second instructional league outing Saturday morning in Tucson, Ariz.

"It was good," Webb told MLB.com. "My curveball was better, my changeup was better, my fastball was 81-83 [mph] which was better than last time. It was another good step. I'm getting a lot more out of these games than I did throwing batting practice or simulated games."

Webb, who threw one inning and 20 pitches in his first instructional league game Wednesday, went two-thirds of an inning and threw 23 pitches this time around.

"I thought it was going to be an easy inning," Webb said.

Instead, the next batter legged out an infield single and he wound up hitting a batter and walking another before being removed.

Webb then went down to the bullpen and threw another 15 pitches.

"I realize that when I'm out there I'm still feeling for my mechanics a little bit," said Webb, who has not pitched in a Major League game since Opening Day of 2009. "So I think there's obviously more velocity in the tank once I get the mechanics down. It felt even better in the pen when I came out."

Webb will throw a side session Monday before wrapping up his instructional league time with another outing on Thursday in the Phoenix area.
