Walker lands on DL with finger blister

SAN DIEGO -- The D-backs placed right-hander Taijuan Walker on the 10-day disabled list Sunday with a blister on his right index finger.

"I don't think it's going to be that long," D-backs GM Mike Hazen said. "This is something he's been dealing with for a few weeks now, and while it was making some progress start to start, it's still something that he's been managing through."

Hazen added that Walker has had to adjust his repertoire in his last few starts to work around the blister. By putting him on the DL now, the team is hopeful that the blister will heal.

"It varied between changeup, slider and even fastball, at times, where he feels it," Hazen said.

Walker tossed six shutout innings Friday night against the Padres and was scheduled to start again Wednesday afternoon against the White Sox at Chase Field. The D-backs have not said who will start in his place.

"That's all still TBD," Hazen said. "We haven't had a chance to really sit down and walk through that yet. We'll obviously have until Wednesday to figure out what we want to sort of do."

The D-backs could call up a starter from the Minor Leagues, but it's also possible they could use a handful of relievers to get through Wednesday's game. Randall Delgado, Archie Bradley, T.J. McFarland and Tom Wilhelmsen are all capable of throwing multiple innings.

Walker is 4-3 with a 3.46 ERA in nine starts this season. He was acquired by the D-backs along with Ketel Marte in December from the Mariners in a trade that sent Jean Segura and Mitch Haniger to Seattle.

McFarland, who had been on the 10-day DL with a left ankle contusion, was activated Sunday.
