And here's a twist to Wednesday's move: The Red Sox already have a pitcher on their staff by the name of Ramon Ramirez.
The newly acquired Ramirez was 0-0 with a 3.65 ERA in 11 games for Cincinnati last season. Tampa Bay claimed him on waivers from the Reds in November, then released him last week.
The Red Sox also signed lefty Fabio Castro. He played in the Toronto system last year, going a combined 9-6 in Triple-A and Double-A.
