Bonser was more of a head case due to weight. Being heavy killed his endurance. He was ok as a rookie. After losing weight he lost something. Liriano pitched well when the games didn't count this year. The Twins being so far out the games don't count for much, Liriano is pitching better. Bonser was a head-case because he couldn't control his fastball, much like Liriano. And excuses like what you've just stated for Liriano were exactly what was being said about Bonser. He has an ERA over 5 and it seems like he hits a batter in every outing. He's been pretty solid lately in terms of runs, but his control still isn't there and I wouldn't be surprised to see him slip in his next few outings. It's been five years after his Tommy John; it's time to start realizing that his current state is what he is - an inconsistent, hard-throwing pitcher. I do tend to agree that retaining him for a price of a Marquis or something is fine.
