Veteran right-hander Scott Baker signed a one-year, $5.5-million contract with the Cubs in November of 2012. However, Baker underwent Tommy John surgery in April of 2012, which explains why he's just now ready to start pitching again.
And speaking of "pitching again," the Cubs have announced that Baker will make his 2013 debut on Sunday when he starts against the Brewers in Wrigley.
Baker, 31, has pitched to a 4.15 ERA (102 ERA+), 1.26 WHIP and 3.44 K/BB ratio across parts of seven major-league seasons, all with the Twins. On his just-completed minor-league rehab assignment, Baker logged a 5.46 ERA in eight starts across two levels. As ESPN Chicago notes, Baker's velocity has been down substantially from his normal levels while pitching in the minors.
