This may come as a surprise to many on the list as pitching is considered to be the weakest aspect of the Jays' game, but under the expertise of manager John Farrell, many Jays pitchers have taking large strides in 2011.
For the starters, Ricky Romero made his first All-Star appearance, has a 12-9 record and 2.78 ERA, good enough for fourth place among pitchers in the AL. As the fifth starter in the rotation, Jesse Litsch has completely turned around this season going 5-3 with 52 strikeouts in comparison to a dismal 2010 record of 1-5 with just 16 strikeouts. Farrell's influence can be seen right through the pitching staff.
Casey Janssen has become the clear-cut set-up man in the eighth for the manager to go to. In 42 innings pitched this season, he has a whopping 43 strikeouts and an ERA of 2.14. The Jays are still searching for a permanent closer, but there is an ongoing battle between Jon Rauch and Frank Francisco for the role.
In addition to the pitchers already up in the bigs, there are pitchers in the system who could also make the jump to the big leagues next year who have the potential to develop into strong pitchers.
If Farrell's expertise in pitching has made such major changes to the performance of many of the Jays' staff this season, it can only improve in 2012.
