Surgery changes Arroyo's retirement plans

PHOENIX -- Bronson Arroyo will undergo Tommy John surgery on his right elbow on Thursday, making him the fifth D-backs pitcher to have the surgery in the past two seasons, and third this year. Daniel Hudson has had it twice.

Any thought of Arroyo retiring early went by the boards with the decision to undergo the surgery, the veteran said.

"I was thinking I might retire at 39 when this [two-year] contract is up, but not anymore," said the veteran right-hander, who is 37. "If I'm going to spend a year rehabbing, I'm going to pitch until I'm 45 if I can. Let's see how it goes."

Arroyo will join Hudson, Matt Reynolds, Patrick Corbin and David Hernandez on the Tommy John rehab treadmill. The D-backs have the righty under contract next season at $9.5 million, with an $11 million option and a $4.5 million buyout for 2016. So it's possible he could pitch again for Arizona.

Corbin and Hernandez had the surgery earlier this year. Considering the usual 12-18-month recovery period, they are not expected back until mid-to-late next season.

Hudson and Reynolds are in different stages of their recoveries. Both are throwing to a certain extent, but neither should be back in the Majors until September, if at all this season, D-backs manager Kirk Gibson said on Wednesday before his club closed a three-game set against the Marlins at Chase Field.

"Well, basically Daniel is just starting to throw again," Gibson said. "He just went through a period where they shut him down again. He'll start throwing aggressively this time through the cycle. Reynolds just got off that cycle and he threw a bullpen yesterday. We're probably optimistically looking at September. Hopefully they can throw some in September, just enough to know they'll be good. We'll shut them down again after the season."

Hudson and Reynolds said on Wednesday that they felt fine and were progressing well in their rehab phases. Neither has been advised of any timetable for a possible return. Corbin, who had the surgery at the end of March, said he's at least three months away from even picking up a baseball.

Gibson: D-backs sticking with Reed as closer

PHOENIX -- Despite having blown his fifth save on his ninth homer allowed in 36 2/3 innings of relief on Tuesday night in a 2-1 loss to the Marlins, Addison Reed is still the D-backs' closer, manager Kirk Gibson said prior to the finale of a three-game series between the two teams.

"No, we're staying with Addison," Gibson said during his morning media session on Wednesday. "He struggled last night. But we had a lot of opportunities last night. At the end, it comes down to him, but it shouldn't have."

Be that as it may, Reed was brought in for the ninth inning holding a 1-0 lead, and the first thing he did was run leadoff hitter Ed Lucas to a 3-1 count before walking him. That set the tone for the inning. After recording the next two outs, Reed was one pitch away from victory with a 2-2 count on Marcell Ozuna when he served a 92-mph fastball right over the plate. Ozuna drilled it above the yellow line on the dark, green hitting eye in dead-center for the game-winning two-run homer.

"You don't want to walk the leadoff hitter with a 1-0 lead. No closer wants to do that," Gibson said. "He gave up the homer, but the walk he puts on beats you. That's tough."

On the home run pitch, Gibson reiterated something he said after the game on Tuesday night: "If you look at it, [catcher] Tuffy [Gosewisch] was set up down and away. He just missed the spot by 18, 20 inches. You ask yourself, why? How can he be more consistent, focus and hit the spots on his pitches? Still, he's our closer. You can't give him four or five things to work on when he's out there in a mental lockdown trying to execute all of his pitches."

That might be even more of a reason to let Reed work on his kinks and his decreasing velocity in another role, but Gibson isn't ready to do that. The right-hander does have 20 saves.

"I haven't even considered it," Gibson said about the possibility of moving the 25-year-old Reed. "He's our closer. He's capable of doing it and he's going to learn some lessons along the way. He's really not that old. It's not like he has years and years of experience. It's all part of it and it should make him better."
