The Philadelphia Phillies have been rolling recently. However, they have hit a brick wall tonight in the form of Texas Rangers starting pitcher Martin Perez. At the time of writing, Perez has shut out the Phillies over five innings. He's struck out five batters and allowed only four hits.This comes as a surprise for a couple of reasons. Firstly, many MLB fans and analysts don't believe that Perez is a "legitimate ace" this season. He's strung together some excellent starts, but many dismissed them as simply being fleeting flashes of skill that wouldn't last.Secondly, Perez is facing the Philadelphia Phillies tonight. This is a team that has charged back from being 10 games under .500 to a 36-32 record. They've won five straight games and seven of their last 10. Even without Bryce Harper in the lineup due to blistering issues, the Phillies are still an offensive workhorse tonight.Perez has put a stop to that so far. Granted, he's issued three walks — all to the same hitter, Rhys Hoskins. However, Perez can't be blamed for that, as Hoskins has been on a tear recently. He's batting .385 over his last 21 plate appearances.Rob Friedman@PitchingNinjaMartín Pérez, Painted 93mph Back Door Two Seamer. 🖌️14611Martín Pérez, Painted 93mph Back Door Two Seamer. 🖌️🎨 https://t.co/f2OALCPXI7Most Twitter users are simply in shock at Perez's performance tonight.

Contenders are hungry for starting pitchers like him.Patrick@bankboy24@senorfern Martin Perez. He’ll be in a different uniform by August 1 though. Kole Calhoun has been good. He will be traded too I imagine. Young talent you ask? That’s the head scratcher lol1@senorfern Martin Perez. He’ll be in a different uniform by August 1 though. Kole Calhoun has been good.
