Before the D-backs' series finale against the Yankees on Wednesday, Webb -- who underwent right shoulder surgery last August -- played long toss and threw off flat ground in the bullpen before toeing the rubber in the 'pen. He said his arm speed there was the fastest it has been during his recent progress. Webb has been throwing off a mound regularly since June 12.
"Anything that I do feels better," Webb said.
Webb added that he's also becoming more consistent at repeating his arm slot, though D-backs pitching coach Mel Stottlemyre Jr. will still stop the righty mid-motion if the angle isn't just right.
Webb, who threw during the D-backs' visits to Boston and Detroit last week, will throw this weekend during Arizona's three-game set in St. Petersburg against the Tampa Bay Rays. Pitching out of the full windup is Webb's next step.
Webb last threw a pitch in a Major League game on Opening Day 2009. He was placed on the 15-day disabled list on April 4 and transferred to the 60-day DL on April 17.
