The Atlanta Braves have decided to move right-hander Reynaldo Lopez to the bullpen as part of a rotation shuffle ahead of their series against the Detroit Tigers. Lopez, who began the season as the team's No. 2 starter, has a record of 1-1 with a 3.74 ERA. Braves manager Walt Weiss indicated that Lopez is addressing mechanical issues in his delivery and is expected to return to the rotation once he resolves these problems. Meanwhile, Spencer Strider is anticipated to make his season debut this weekend against Colorado after recovering from a strained oblique. The Braves' rotation will also feature Martin Perez (1-1, 2.70 ERA) starting Tuesday, rookie JR Ritchie, who impressed in his debut, on Wednesday, and Bryce Elder (3-1, 1.95) on Thursday. Weiss acknowledged that more changes to the rotation may be necessary as the season progresses, especially with other pitchers like Spencer Schwellenbach and Hurston Waldrep expected to return from injuries later this season.
