The D-Backs announced a handful of moves on Thursday’s off day. Arizona activated Ryne Nelson from the 15-day injured list and recalled outfielder Alek Thomas from Triple-A Reno. The Snakes optioned Yilber Diaz and Blake Walston to open spots on the active roster.
Nelson’s return is the biggest development. The right-hander has had a strong second half, working to a 3.39 ERA while striking out more than 27 percent of opponents since the All-Star Break. Nelson outpitched Jordan Montgomery to solidify his rotation spot. He held that job until the middle of September when a bout of shoulder inflammation sent him to the injured list.
That temporarily drew Montgomery back into the starting five. Arizona could use both Nelson and Montgomery out of the bullpen this weekend. The D-Backs will start Merrill Kelly on Friday to kick off their weekend series with the Padres. They haven’t announced starters for their final two games. Eduardo Rodriguez and Brandon Pfaadt would be on schedule. They’re the third and fourth starters on paper, although Nelson had been handily outperforming both in the weeks leading to his IL placement. Zac Gallen tossed 97 pitches over six innings against the Giants on Wednesday. He’s potentially an option for Sunday on three days rest if the D-Backs are playing a must-win game…
