Seth McClung has been traded to the Brewers for Grant Balfour.
Balfour, 29, is originally from the Twins organization spent last season recovering from surgery. This year he's recently been with the Nashville Sound his stat line: 32 IP, 17 H, 6 ER, 2 HR, 47 K, 11 BB (no 'ball four' jokes), 4.8 H/9, 0.56 HR/9, 3 BB/9, 13 K/9 (!), a 1.69 ERA and a 0.88 WHIP.
Grant will join the Rays pen tomorrow, with Ryu likely headed to AAA.
Scouting report: (TSN.ca)
Balfour has some good heat, into the mid-90s, and he mixes it with a strong sinker/slider combo. He's a rare righty that's killer against left-handed hitters.
