... for lefty Javier Lopez once a Rule V pickup by Boston in 2002, later traded to Colorado). He should be with the team in Minnesota tonight.
With the AAA Charlotte Knights (International League) this year, he posted a puny 0.55 ERA in 33 innings (28 hits, 6 walks, 26 strikeouts). And he's had decent WHIPs in the minors for three years (1.06, 1.33, 1.19).
In 115.1 career major league innings, however, he has a 6.09 ERA (79 ERA+) and a ton of walks.
Riske threw only nine innings for the Sox and he certainly wasn't going to get into any high-leverage situations, so I don't hate this or like this move. It just is. Tito wanted a LOOGY with Foulke out, so Theo got him one.
