Martín Pérez: Everything you need to know

Perez (2-2) took the loss Wednesday against the Mariners, allowing two runs on five hits and a walk over 5.2 innings. He struck out five. It was announced Wednesday morning that Perez would get the start instead of Grant Holmes, and the southpaw was solid, holding Seattle to one run through his first five innings before Julio Rodriguez added on with a solo shot in the sixth. However, Atlanta's offense couldn't muster anything against Bryan Woo in an eventual 3-1 defeat, leaving Perez with his second loss. Overall, Perez has been solid as a swingman for Atlanta this year. His ERA sits at 2.38 with a 1.00 WHIP and 24:11 K:BB across 34 innings.

Perez will start Wednesday's game against the Mariners in Seattle. Grant Holmes had initially been listed as Atlanta's starter for Wednesday, but the team will instead pivot to Perez after the veteran southpaw wasn't needed in relief in the first two games of the series. According to Mark Bowman of MLB.com, the change doesn't necessarily mean that Perez will be a regular in the rotation moving forward, or that Holmes will be headed to the bullpen on anything more than a short-term basis. Whether he's been used as a starter or reliever, Perez has been excellent this season; he'll take a 2.22 ERA and 0.99 WHIP over 28.1 innings into Wednesday's outing.

Atlanta manager Walt Weiss said that Perez wasn't available out of the bullpen for Monday's 5-4 loss to Seattle because the left-hander might be needed to start one of the final two games of the series in Seattle, Mark Bowman of MLB.com reports. Atlanta has already confirmed Bryce Elder and Grant Holmes as its starters for Tuesday and Wednesday, respectively, but Weiss's comments may indicate that one of the two is not necessarily locked into taking the hill that day. Though he had been expected to shift to the bullpen when Atlanta brought back Spencer Strider from the injured list over the weekend, Perez looks like he could still be a factor in the rotation. Whether he makes his next appearance as a starter or a reliever, Perez will be fresh after having not pitched since last Tuesday, when he tossed five scoreless innings against Detroit to bring his ERA down to 2.22 for the season.
