According to MLB.com’s Steve Gilbert, new Diamondbacks pitcher Taijuan Walker said he was dealing with 10 bone spurs in his right foot, which impacted his ability to push off and use his lower body. The biggest bone spur was three-fourths of an inch in size, Gilbert adds.

Moving from the more pitcher-friendly Safeco Field in Seattle to the more hitter-friendly Chase Field in Arizona, Walker said he plans to add a two-seam fastball in an attempt to keep the ball on the ground. The 24-year-old last season allowed 27 home runs in 134 1/3 innings. As a percentage of fly balls, his 17.6 percent home run rate was eighth-highest among pitchers who logged at least 130 innings. Despite the home run issues, Walker did manage to keep his ERA at 4.22 while averaging better than three strikeouts for every one walk. If he’s able to tamp down the homers, it will be interesting to see if he can live up to his potential with the Diamondbacks.
