Reynaldo López: Everything you need to know

Lopez will be utilized as a reliever going forward while working on some mechanical issues, Mark Bowman of MLB.com reports. The right-hander's 3.74 ERA through five starts this year looks solid, but his 1.43 WHIP and 20:11 K:BB tell a different story. Atlanta will soon be getting back Spencer Strider (oblique) from the injured list, and Martin Perez will pick up a spot start Tuesday versus Detroit before Strider likely enters the rotation next weekend.

Lopez (1-1) took the loss Tuesday against the Nationals, allowing four runs on five hits and three walks with one strikeout across one inning. Lopez allowed three runs on three hits and three walks in a 46-pitch first inning, as the Nationals batted around. James Wood then led off the second inning with a solo shot ahead of a Luis Garcia single, and Lopez's night was done after 58 pitches. It was Lopez's shortest start since going 0.2 innings in July of 2020. The right-hander now owns a 3.74 ERA and 20:11 K:BB across 21.2 innings to begin the 2026 campaign. Lopez is tentatively scheduled to next take the mound Sunday at home against the Phillies.

Lopez did not factor into Tuesday's decision against the Marlins, allowing four runs (three earned) on five hits and three walks while striking out six across five innings. Lopez was back in the rotation for Atlanta after serving his five-game suspension. He got off to a rough start by allowing four runs through the first two innings, but he settled in to keep the Marlins off the board for the rest of his outing. Lopez generated only five whiffs on 96 pitches (53 strikes) but struck out five of the last 10 batters he faced. Through four starts, Lopez has a 2.18 ERA, 1.11 WHIP and 19:8 K:BB over 20.2 innings. His next start is tentatively slated for this weekend on the road against the Phillies.
