The Rangers have traded 37-year old lefty reliever Eddie Guardado to the Twins for 21-year old righty reliever Mark Hamburger. Guardado was working as the closer for the Rangers after he replace the injured C.J. Wilson in that role. Guardado pitched in 55 games (0 starts) for the Rangers this season and he was 3-3 with 4 saves, a 3.65 ERA and a 1.11 WHIP. The Rangers will likely replace Guardado at closer with flamethrowing righty Frank Francisco. Francisco has pitched in 47 games (0 starts) this season for the Rangers and he is 2-5 with a 3.78 ERA and a 1.24 WHIP. He has allowed only 43 hits in 52.1 innings this season for the Rangers while whiffing 65 batters. So, he definately has the stuff to succeed in this role so it will be interesting to see if he can handle it or not. 21-year old righty reliever Mark Hamburger pitched in 27 games (0 starts) in rookie ball for the Twins this season and he is 1-2 with 13 saves, a 4.17 ERA and a 1.31 WHIP. He has whiffed 40 batters in only 36.2 innings this season which shows that he has decent stuff.
