some spring training stats:
Jensen: 6 ip, 7.50 era, 5 er, 7 h, 0 bb, 3 k
Ainsworth: 5 ip, 3.60 era, 2 er, 6 h, 0 bb, 4 k
Foppert: 5 ip, 1.80 era, 1 er, 1 h, 4 bb, 6 k
Small sample size but it falls in line with what I think of the three. Jensen is awful but pacbell saves his stats. Ainsworth's control isnt as good as 0 bb in 5 ip but if he is given the 5th starter role, he probably ends up with a 3.8-4.2 era with good k. Jensen should be traded, Ainsworth should be the 5th starter, and Foppert should start the season in AAA and be called up if someone in the rotation goes down for an extended amount of time.
... doubt this happens though.
