Kicking off this season's (usually) weekly rundown of top performers from the minor leagues, we'll also take a look at some names that aren't off to a hot start in the developmental ranks.
Class A Lakewood-

In three starts, right-hander Mark Leiter Jr. has a 2-1 record and a 3.00 ERA while striking out 15 and walking two in 18 innings of work. Leiter was drafted in the 22nd round last year out of the New Jersey Institute of Technology.
Third baseman Zach Green is having a slow start at the plate, batting .186 with two doubles, four RBI and three steals in 15 games. The 20-year-old righty hitter was selected in the third round of the 2012 draft.

Outfielder Justin Parr is struggling to start his first full year in the pro's. The lefty batting 23-year-old has posted a .082 average with a double and two RBI in 13 games for the Threshers. Parr, an eighth round draft choice last year, posted a .247/.332/.353 line in 56 games with short-season Class A Williamsport in 2013.

While adapting to the new position, the youngster, who was an All-Star second baseman in the minors, has three errors.

Fightins closer Ken Giles looks great thus far this season. In six appearances, the 23-year-old righty has notched five saves and has yet to allow a run. In seven innings of work, the Phils' seventh round pick from 2011 has recorded 16 strike outs and has walked three batters. With just one hit, opponents are batting .043 against Giles.
