Nelson came away with a no-decision in Friday's 6-5 loss to the Angels, coughing up four runs on seven hits and four walks over four innings. He struck out one.

EDGE Analysis

He tossed 52 of 87 pitches for strikes before getting the hook, and he was lucky to last that long after Zach Neto and Yoan Moncada both took him deep in the first inning. It was the first time all season that Nelson has served up multiple homers in the same outing, and Friday's ragged performance ended a strong stretch for the 27-year-old right-hander in which he'd allowed two runs or fewer in five straight starts. Nelson will look to regroup over the All-Star break as he takes a 3.68 ERA, 1.07 WHIP and 65:25 K:BB through 78.1 innings into the second half.

Nelson (5-2) earned the win Saturday against the Royals, allowing one run on four hits and no walks over seven innings. He struck out five.

EDGE Analysis

Since surrendering seven runs over three innings June 3 in Cincinnati, Nelson has been lights out, giving up just five earned runs with a 0.78 WHIP and 36:6 K:BB across his past five starts. The right-hander opened the campaign as a reliever, but he's taken advantage of the absence of Corbin Burnes (elbow) and has pretty well cemented his spot at the back end of Arizona's rotation. Nelson has a 3.39 ERA, 0.98 WHIP and 64:21 K:BB over 74.1 innings, and he lines up to face the Angels on the road next weekend.

Nelson allowed two runs on five hits and struck out seven without walking a batter over 6.2 innings in a no-decision versus the Giants on Monday.

EDGE Analysis

Nelson was cruising until he put two runners aboard in the seventh inning, both of which came around to score when Juan Morillo allowed a two-run double to Tyler Fitzgerald. That cost Nelson a chance at the win, but this was still another impressive start. He has allowed just five runs (four earned) over 22.1 innings while adding a 21:6 K:BB across his last four starts, so it's a bit unlucky he's come away with just two wins in that span. On the year, Nelson has a 3.61 ERA, 1.02 WHIP and 59:21 K:BB through 67.1 innings over 18 appearances (eight starts). His next start is projected to be at home versus the Royals this weekend.

Nelson allowed one run on one hit and three walks while striking out seven in five innings Tuesday against the White Sox. He did not factor into the decision.

EDGE Analysis

Nelson recorded six of the first seven outs via strikeout. He relied heavily on his four-seamer, throwing it nearly 80 percent of the time, and racked up six of his seven punchouts with the pitch. Nelson has allowed just two hits over his last two starts and has allowed two earned runs over his last 15.2 innings. He lines up for a home start versus the Giants to begin next week.

Nelson (4-2) earned the win against the Blue Jays on Thursday, allowing one run on one hit and two walks while striking out four across 5.2 innings.

EDGE Analysis

Nelson faced the minimum number of batters in four of the six innings he pitched, with his lone blemish coming in the second inning when he yielded a solo home run to Alejandro Kirk. Nelson has allowed one earned run or less in five of six starts this season and has seemingly earned the spot in the Diamondbacks' rotation that opened up following Corbin Burnes' season-ending elbow injury that will require Tommy John surgery. Nelson is lined up to face the White Sox on the road next week.

Nelson (3-2) allowed one unearned run on six hits and a walk while striking out three over five innings to earn the win over the Padres on Friday.

EDGE Analysis

Nelson gave up seven runs over just three innings in Cincinnati in his last start, but a return home served him well. He's allowed just one unearned run over 15.2 innings across his last three home appearances. The right-hander appears to have done enough for now to hold onto a spot in the rotation, which opened up when Corbin Burnes (elbow) suffered a season-ending injury and subsequently elected for Tommy John surgery. Nelson has maintained a serviceable 4.14 ERA, 1.14 WHIP and 41:16 K:BB across 50 innings over 15 appearances (five starts) this season. His next start is projected to be at Toronto.

Nelson (2-2) took the loss against the Reds on Saturday, allowing seven runs on four hits and four walks while striking out three across three innings.

EDGE Analysis

Nelson put the Diamondbacks in the hole right out of the gate after yielding five runs in the first inning, three of which came a Christian Encarnacion-Strand three-run homer. Nelson settled in to keep the Reds off the board over the next two frames, but he was pulled in the fourth and tagged for two more runs. It was a rough outing for the 27-year-old right-hander, who is looking to keep a permanent spot in the Diamondbacks' rotation with Corbin Burnes (elbow) scheduled to undergo Tommy John surgery. Nelson will look to bounce back in his next start, tentatively slated for next weekend at home against the Padres.

Nelson is slated to start Saturday's game against the Reds at Great American Ball Park.

EDGE Analysis

Nelson will pick up his fourth start of the season Saturday and could have an opportunity to stick around in the rotation for the remainder of 2025 with Corbin Burnes (elbow) set to undergo Tommy John surgery next week. Since being lit up by the Cubs for five earned runs while recording just two outs in an April 18 game, Nelson has pitched to a 1.72 ERA, 0.86 WHIP and 23:9 K:BB in 31.1 innings.

Nelson will move into the Diamondbacks' rotation following the injury to Corbin Burnes (elbow), John Gambadoro of Arizona Sports 98.7 FM reports.

EDGE Analysis

Nelson has yielded just three runs over 16 innings in three starts this season, although that's come with an underwhelming 8:6 K:BB. It's not known when he will make his next start for the Diamondbacks, but his last appearance came on Saturday when he tossed four scoreless relief innings against the Nationals.

Nelson could rejoin the starting rotation if Corbin Burnes (elbow) misses starts, Alex Weiner of Arizona Sports reports.

EDGE Analysis

Burnes was removed from Sunday's start with elbow discomfort and will undergo an MRI on Monday. If Burnes needs to miss time, the Diamondbacks are set up to deal with it. Eduardo Rodriguez (shoulder) is set to return and reclaim his spot in the rotation during an upcoming road trip. For potential replacements for Burnes, Ryne Nelson, who had filled in for Rodriguez and was recently moved back to the bullpen, is one option. Another is Cristian Mena, a minor league starter who was called up Sunday and pitched two innings in a 3-1 win over Washington.
