Dbacks Notes

Jameson was optioned to Triple-A Reno on Monday, Aaron Hughes of SI.com reports.

Jameson appeared in three games during his stint with the big-league club, one of which resulted in his first save April 20 against the Cubs. This move will presumably clear a roster spot for the return of Kevin Ginkel (shoulder) from the 15-day injured list, though the club has yet to officially announce a corresponding move.

Pfaadt (5-1) allowed three runs (two earned) on nine hits and a walk over six-plus innings Sunday, striking out six and earning a win against Atlanta.

Pfaadt delivered four shutout frames before Atlanta finally broke through with a run in the fifth inning. They put two more runs on Pfaadt’s line in the seventh, including one after he was removed from the game. He tossed 65 of 100 pitches for strikes and forced 13 whiffs, including nine with the sweeper. Pfaadt has won five consecutive starts and dropped his season ERA to 2.78 to go along with a 29:6 K:BB.

Martinez allowed a run on one hit and two walks in one inning during Sunday’s win over Atlanta. He earned a save and did not record a strikeout.

Martinez entered a 6-3 game and was not very effective. On top of the two walks, he also hit a batter. A double play before Marcell Ozuna’s RBI double helped limit the damage to just one run. Martinez entered the game with a clean 0.00 ERA through nine innings. He didn’t walk a batter in his first seven appearances but has now issued four free passes over his last 3.1 innings. Martinez was recently dealing with some shoulder fatigue but is the current favorite for saves with A.J. Puk (elbow) on the IL, though Shelby Miller may also be in the mix.

Naylor went 3-for-4 with two doubles, two RBI and a run scored in Sunday’s 6-4 win over Atlanta.

Naylor knocked in two insurance runs with a seventh-inning double a half an inning after Atlanta trimmed the Diamondbacks‘ lead to 4-3. The three-hit effort followed a stretch during which Naylor went 1-for-15 in Arizona’s four-game losing streak.

Perdomo went 1-for-4 with a home run, two RBI, two steals and an additional run scored in Sunday’s 6-4 win over Atlanta.

Perdomo knocked in Corbin Carroll after the latter led off the bottom of the first with a triple. The shortstop then hit his fourth homer of the season in the fifth inning. It was a productive game for Perdomo, who endured a fallow stretch entering the game, going 2-for-27 with zero RBI over the last seven contests.
