Even though Diamondbacks pitcher Daniel Hudson’s day-to-day routine hasn’t changed that much as he works back from Tommy John surgery, he’s at least happy the regular season has started.

“Spring training is a little rough,” Hudson said. “For everybody, spring is seven weeks long. Up at the park every morning at 6 o’clock. It’s nice to get out and not be in spring training and come out here and get regular-season games that really count and watch those.”

Of course, Hudson would prefer to be more than just a bystander, but that’s at least three months away. On Tuesday, Hudson was exactly nine months removed from surgery. The club hopes to have him back around the All-Star break in mid-July.

Hudson feels like he’s on track to make his 2013 debut around that time and hasn’t suffered any setbacks other than general soreness.

Tuesday he threw all of his pitches in a bullpen session and will follow that up with another on Friday before facing live batters next Tuesday, barring a setback.

“He’s throwing the ball very well,” Diamondbacks manager Kirk Gibson said.

Hudson was 3-2 with a 7.35 ERA in nine starts in 2012, but won 16 games with a 3.49 ERA in 2011.
