ST. PETERSBURG -- Rays manager Kevin Cash confirmed lefty Ryan Yarbrough will start Wednesday against the Braves, but wouldn't commit to Yarbrough as the the club's No. 4 starter beyond that outing.
"With the lineup that they're featuring, if we're being completely honest, they throw a lot of lefties at the top," Cash said. "With [Yarbrough] being left-handed, I think he can give us some length." 
The Rays are down a starter with right-hander Yonny Chirinos landing on the disabled list with a right forearm strain last week. He's expected to be out for about a month.
Yarbrough is coming off a dominant relief appearance against the Blue Jays on Friday. The lefty allowed one hit over five scoreless innings, retiring the final 15 batters he faced. He has given up just two runs over his last nine innings pitched.

Worth noting
• This week's two-game set will be the first time the Rays get to see the Braves' young duo of Ronald Acuna Jr. and Ozzie Albies up close. Heading into the season, the Braves came in with the No. 2-ranked farm system, according to MLB Pipeline's Jonathan Mayo, while the Rays were ranked No. 4.
"It certainly seems like they have a core of young players that are very talented," Cash said before Tuesday's game against the Braves. "We feel pretty strongly about our core and hopefully, when our guys get up, they can have some success just like these guys are having."
• With Saturday's doubleheader scheduled vs. the Orioles, Cash says that righty Chris Archer will start one of the two games, while the other game will probably be a bullpen day.
"We don't know who that would be, but we'll probably find out as we get closer to that day."
