Nelson (2-3) allowed eight runs on 11 hits and a walk while striking out four over four-plus innings to take the loss versus the Tigers on Friday.

EDGE Analysis

Nelson avoided giving up a home run for the first time in three outings since he returned from an elbow injury, but that was the only silver lining on a dark cloud in this start. He allowed five runs over the first four innings and then failed to get an out in the fifth as the Tigers piled on. This was Nelson's worst start of the season, but he's generally struggled with a 7.06 ERA, 1.88 WHIP and 23:7 K:BB over 29.1 innings through seven appearances. He's tentatively projected for a difficult road start versus the Dodgers in his next outing.

Nelson came away with a no-decision in Saturday's 5-4 extra-innings loss to the Orioles, giving up three runs on 10 hits over 4.2 innings. He struck out three without walking a batter.

EDGE Analysis

Half of the hits off Nelson went for extra bases, including a pair of doubles plus a triple by Ryan Mountcastle and a solo homer by Gunnar Henderson. Nelson has lasted past five innings only once in six starts this season, and he'll carry a 5.33 ERA, 1.70 WHIP and 19:6 K:BB through 25.1 innings into his next outing, which lines up to come at home next weekend against the Tigers.

Nelson (2-2) picked up the win over the Padres on Sunday, allowing four runs on eight hits and a walk while striking out three over five innings.

EDGE Analysis

Nelson wasn't spectacular in his return from a trip to the injured list, but he didn't need to be after the Diamondbacks plated 11 runs through five innings. Nelson served up a two-run homer to Jackson Merrill in the second before Kyle Higashioka doubled in Ha-Seong Kim after he walked. The Padres would scratch across another run in the third before being silenced the rest of the way. Nelson was able to get up to 99 pitches and has slid into the rotation spot of Tommy Henry who was optioned to Triple-A Reno last week. Nelson owns a 5.23 ERA, 1.60 WHIP and 16:6 K:BB in 20.2 innings and is slated for a tough road matchup against Baltimore his next time out.

The Diamondbacks activated Nelson (elbow) from the 15-day injured list ahead of his start against the Padres on Sunday.

EDGE Analysis

The right-hander has been sidelined the past couple weeks by an elbow bruise but is rejoining Arizona's rotation Sunday. Nelson could face some minor workload limitations given he hasn't pitched in a game since April 18.

Diamondbacks manager Torey Lovullo confirmed Saturday that Nelson (elbow) will return from the injured list to start Sunday against the Padres, Theo Mackie of The Arizona Republic reports.

EDGE Analysis

Lovullo had indicated previously that it was likely to be Nelson making the start, and now he's made it official. The right-hander had to go on the IL in mid-April after taking a comebacker off his pitching elbow, but he'll make a return Sunday after skipping a rehab assignment. Nelson holds a 4.60 ERA, 1.53 WHIP and 13:5 K:BB in 15.2 innings this season.

Diamondbacks manager Torey Lovullo said Nelson (elbow) will "most likely" return from the 15-day injured list to start Sunday's game versus the Padres at Chase Field, Jesse Friedman of GoPHNX.com reports.

EDGE Analysis

On the shelf since April 19 with a bruised right elbow, Nelson has bounced back well enough since he resumed throwing to avoid a minor-league rehab assignment. Nelson will presumably throw another bullpen session Friday, and if all goes well, he'll take the hill Sunday with few restrictions, if any. Through his first four starts for Arizona before landing on the IL, Nelson went 1-2 with a 4.60 ERA, 1.53 WHIP and 13:5 K:BB in 15.2 innings.

Diamondbacks manager Torey Lovullo said Monday that he expects Nelson (elbow) to be back "soon enough," and that the right-hander may not need a rehab assignment, Jesse Friedman of GoPHNX.com reports.

EDGE Analysis

Nelson threw a five-inning, 70-pitch sim game Monday and did not experience any pain. The 26-year-old landed on the 15-day IL on April 19 due to right elbow contusion, but it appears Nelson could return when first eligible for activation May 4 against the Padres.

Diamondbacks manager Torey Lovullo said Nelson (elbow) will throw a bullpen session Wednesday, Theo Mackie of The Arizona Republic reports.

EDGE Analysis

Nelson went on the 15-day injured list last week after being struck on the pitching elbow by a comebacker. He appears to be making a quick recovery, and he could have a shot to return when first eligible for activation May 4 or shortly thereafter.

The Diamondbacks placed Nelson (elbow) on the 15-day injured list Friday.

EDGE Analysis

Nelson left Thursday's game against the Rockies after he took a comebacker to his arm in the second inning. Nelson will be replaced on the active roster by left-hander Jordan Montgomery, who will make his season debut Friday against the Giants. Nelson has started in four games this season, posting a 4.60 ERA, 1.53 WHIP and 13:5 K:BB over 15.2 innings.

Nelson exited Thursday's start against the Giants due to a right elbow contusion.

EDGE Analysis

Nelson took a comebacker to his arm while recording the final out of the second inning and was forced to exit the game. It appears that he's avoided a fracture or other more serious injury, so it remains possible that he's available for his next turn through the rotation.
