Ricky Tiedemann Debuts, Vladdy Hits the IL

Yeah, I know, I'm a little late to the party on this. But we couldn't just not have anything on the site about all the news from before today's game. Here's the rundown:

• Ricky Tiedemann was promoted for his MLB debut.
• Chase Lee was optioned back to Buffalo. That's option number five for Lee this season. 
• Vladimir Guerrero Jr. is in concussion protocol. He's out for at least a week.
• Daz Cameron had his contract selected from Triple-A Buffalo. He's on the roster now.
• Lazaro Estrada was designated for assignment. Similar to Lee, he had been optioned the maximum number of times, which limited his flexibility. A player can't be optioned more than five times in a season.

Tiedemann made his debut this afternoon, tossing 1.2 innings. He gave up one run on two hits and struck out two.
