Ryne Nelson: Everything you need to know

Nelson took a no-decision Monday against the Orioles, allowing two runs (one earned) on three hits and two walks in 5.1 innings. He struck out seven. Though Nelson held Baltimore to just three knocks Monday, two of which went for extra bases. The right-hander fanned a season-high seven, and Nelson has now kept the ball in the yard in back-to-back starts after serving up a pair of long balls in each of his prior two outings. Nelson, who owns a strong 3.54 ERA, 1.03 WHIP and 19:8 K:BB over 20.1 innings, has given up three hits or fewer three times this year but is set for a tough test this weekend against Toronto.

Nelson (1-1) allowed one run on five hits while striking out five over 5.2 innings, earning the win in Wednesday's 7-2 victory over the Mets. Nelson's first two starts of the season were marred by six walks and four home runs, uncharacteristic of the right-hander. There were no such issues the third time out. Nelson scattered two hits over five scoreless innings, before New York batters touched him for three singles and their lone run in the sixth. The bounce-back outing came at a good time for Nelson, as the Diamondbacks consider how best to incorporate Merrill Kelly (back) into the rotation. Kelly is scheduled for one more rehab start before being activated, meaning someone in the existing rotation will need to go. Based on the results thus far, the decision seemingly comes down to Nelson (4.20 ERA) and Brandon Pfaadt (6.75).

Nelson (0-1) took the loss against Atlanta on Thursday, allowing seven runs (two earned) on three hits and three walks while striking out three batters over 4.2 innings. Nelson fell behind quickly by allowing a solo home run to Matt Olson with two outs in the first inning. Another solo shot -- this time by Dominic Smith -- put Atlanta up 2-0 in the third, but it wasn't until the fifth frame that things really unraveled for Nelson. An error behind him on a potential inning-ending double play opened the floodgates, as Atlanta went on to score eight runs following the miscue. Fantasy managers who deployed Nelson at least didn't have their ERAs wrecked since all of the runs in the fateful fifth were unearned, but this was nonetheless an uninspiring performance by the right-hander, who also battled his control with three walks. Through two starts, Nelson has allowed 11 runs (six earned) with a poor 7:6 K:BB over 9.1 innings.
