Dr. Jekyll and Mr. Hyde

Jose Contreras, RHP, White Sox (Triple-A Charlotte)
Monday's stats: 9 IP, 1 H, 0 R, 3 BB, 5 K
Two weeks ago, could you have imagined Contreras throwing a one-hitter at any level? But there he was Monday night, carrying a no-hitter into the eighth inning and needing just 100 pitches to cruise to the shutout victory. True progress, or another indication of how massive the difference is between even the highest level of the minors and the big leagues?

As if Toronto needs more good news

J.P. Arencibia, C, Blue Jays (Triple-A Las Vegas)
Monday's stats: 3-for-3, 2B, 2 HR (7), 2 R, 4 RBI, 2 BB
Like Baltimore uber-prospect Matt Wieters, Arencibia was a first-round pick in 2007, and like Wieters, he hit 27 home runs in his full-season debut while splitting time between high Class A and Double-A. A free-swinging approach led some to doubt his ceiling, as did the fear that he would be exposed by experienced Triple-A breaking-ball specialists. That seemed to be a legitimate concern when he hit .224 without a home run in April, but May has been a different story, as Arencibia is slugging .697 with seven bombs in 66 at-bats while also learning the value of a little patience with seven walks.
