ST. LOUIS (AP) The St. Louis Cardinals promoted a fresh arm from the minors for the second straight day, recalling rookie right-hander Michael Blazek from Triple-A Memphis and demoting rookie right-hander Carlos Martinez.
The 24-year-old Blazek has appeared in 10 games with St. Louis with an 8.31 ERA in 8 23 innings before Wednesday night's game against the Reds. He's 1-2 with a 2.77 ERA and two saves in 19 games at Memphis.
The 21-year-old Martinez is one of the franchise's top pitching prospects and earned his first career victory Monday, working two innings of relief.
The Cardinals sent rookie Tyler Lyons to Memphis on Tuesday, a day after the lefty started against Cincinnati, and promoted right-handed reliever Fernando Salas.
