Schultz, 28, will wear No. 58. He went 8-7 with a 5.75 ERA (75 ER in 117.1 IP) in 21 starts (8 quality) for Reno. At the time of his promotion, he led the Aces in wins, games started and innings pitched, and recently recorded his first career complete game on July 20 vs. Tacoma in a rain-shortened, 7.0-inning victory.
He made his first Opening Day roster for the Opening Series in Sydney, Australia and recorded a scoreless inning of work vs. Dodgers in his lone appearance with the D-backs this season. He was optioned to Reno on March 29. Over 7 Minor League seasons in the Oakland A's (2008-11) and D-backs' (2012-14) organizations, Schultz has gone 31-25 with 13 saves and a 4.22 ERA (210 ER in 448.0 IP) in 192 games (44 starts). He was signed by Arizona as a Minor League free agent on March 8, 2012.
Marte, 25, played in 16 games over 2 stints (May 2-27 & July 22-29) with Arizona this season and hit .258 (8-for-31) with 1 home run, 3 doubles and 7 RBI. He became the first D-back to hit a grand slam for his first Major League home run during a pinch-hit appearance on July 25 @ Phillies.
The D-backs' 40-man roster is remains at 37.
This may end up being a short-term move, largely to provide an extra arm in the bullpen for a couple of days, Between Josh Collmenter's short start on Sunday, and last night's 15-inning marathon, the Diamondbacks' relievers have thrown a total of 15.2 innings - scoreless ones at that - over the last three games, so have been heavily taxed. With Trevor Cahill starting tonight's game - not exactly what I'd call a banker bet to go deep - it makes sense to have someone like Schultz available, who can work as a long reliever. He started for the Aces on the 25th, but only lasted 3.2 innings.
