Sometimes you worry about a guy's timing when he comes back from a nagging injury. Don't worry about Sweeney. He has 12 hits in 30 at-bats to go with eight RBIs since returning to the lineup. The 18-year-old from Maryland leads the Arizona Summer League with a .467 on-base percentage and .617 slugging percentage.
2) Sean O'Sullivan, RHP, Orem (3)
He has not allowed an earned run in four of his six starts, sports a 1.67 ERA overall and has more strikeouts in each game than walks allowed so far this year. The righty from San Diego sports a 23-2 strikeout-to-walk ratio and is just starting to stretch out his appearances, going six innings to get his first victory on Sunday.
3) Esmerlin Jimenez, RHP, AZL (NR)
The righty has rebounded from a rough debut to give up just five earned runs over his last 29 innings of work. Jimenez showed improved command in his second year of the Dominican Summer League in 2005, but his two walks – against 20 strikeouts – in 24.1 innings of work this month are a pleasant surprise for everyone.
4) Trevor Bell, RHP, Orem (5)
The righty from Hollywood has given up just four runs in his last four starts, a span of 22 innings. Although he has just 22 strikeouts in 38 innings, last year's top Angels draft pick has walked only six and is holding opponents to a .239 average.
5) Chris Pettit, OF, Orem (NR)
The Loyola Marymount University product leads the Owlz with a .283 average, .436 on-base percentage, .525 slugging percentage and 19 RBIs, so it is no coincidence that he's the highest rated position player from Orem. The right-hander has also played solid defense at all three outfield positions and provides a patient, more developed approach at the plate.
6) Ryan Mount, 3B, Orem (NR)
One of only two Owlz with an OPS over .800, Mount is second in the Pioneer League with six home runs and has scored a club-high 20 runs in 28 games. The left-handed hitter is hitting .327 against righties and has a .303 mark with runners in scoring position.
7) Felipe Arredondo, RHP, Orem (2)
Though he has struggled of late, giving up five earned runs in his last 4.2 innings of work, the righty still sports a 2.89 ERA and has 29 strikeouts in 18.2 innings of work. Opponents continue to hit just .185 against him, but three of the last four hits he has allowed have left the ballpark.
8) Willie Ortiz, SS, AZL (NR)
Long Island's Dowling College isn't exactly a regular stop for most scouts, but the 20-year-old from Brooklyn is doing his best to make the school proud. The 33rd round pick is hitting .353 in 14 games since signing and had reached base in every start before Sunday.
9) Tim Schoeninger, RHP, AZL (9)
Despite giving up three runs in back-to-back games, Schoeninger still has a 2.76 ERA to rank eighth in the Arizona League. The righty has walked just two batters in 29.1 innings and has given up only three extra-base hits.
10) Seth Loman, 1B, AZL (NR)
Getting a spot on this list even though his average remains under .200 for the year, Loman has nine RBIs over his last seven games thanks to a pair of homers and three doubles in that stretch. The big switch-hitter has got to start doing something from the right side if he wants to avoid having the team limit him to hitting only from the left side, but his power is enough to warrant continued attention.
Moved off the list:
Hank Conger, C (4) Who really wants a hook of hamate anyway?
Alex Fonseca, SS (6) Just 4-for-17 since missing 10 games, we'd be shocked if he's not back in the top 10 next time.
Amalio Diaz, RHP (7) Moved up to Cedar Rapids, but he's now on the DL
Angel Castillo, OF (8) Just two hits in his last 20 at-bats
Peter Bourjos, OF (10)Hitting .203 this month to prove that all those strikeouts catch up with you
Editor's Note: In our first short-season rankings, we mistakenly reported that Angel Castillo led the Dominican Summer League in homers and RBIs last season. In fact, Castillo is making his professional debut this year. His teammate in Arizona, Norberto Ortiz led the DSL. We apologize for the error.
