The Wisconsin Timber Rattlers roster includes four players ranked by Baseball America among the Milwaukee Brewers’ top 30 prospects.

Two of those players — outfielder Monte Harrison (No. 14) and infielder Jake Gatewood (No. 16) — started the 2015 season with the Timber Rattlers as the result of aggressive promotions. Both of them struggled at the plate, sustained significant injuries, and ended their seasons in the rookie-level Pioneer League. They recovered well with the Helena Brewers, and now get a second crack at the Midwest League.

Baseball America said this about Harrison:

When healthy, Harrison is an exciting, athletic player to watch. He can be dynamic on the basepaths, using plus speed and daring to steal bases and go from first to third base in a flash. Harrison has plus bat speed with an advanced approach and plate discipline. His athleticism and speed also plays well in center field, where he chases down flies with ease. But he also has enough arm strength to play right field if his power develops.

BA calls Gatewood “a high-risk/high-reward player” who needs to improve his all-or-nothing approach. He is fine defensively at shortstop, but there is talk of him moving to third base due to organizational needs, so it will be interesting to see how much time he splits between those two positions this year.

Another player to watch on the left side of the diamond is Isan Diaz, who is primarily a shortstop (though he also has played some second base). Last year he batted .360 with 13 HR, 51 RBI and 12 SB in 68 games with the rookie-level Missoula Osprey. Baseball America had him ranked No. 9 among Arizona Diamondbacks prospects before the Brewers acquired him.

Two right-handed pitchers — Marcos Diplan (No. 18) and Miguel Diaz (No. 25) — appear on BA’s Brewers prospects list. Diplan went 2-2 with a 3.75 ERA, 54 strikeouts and 21 walks in 50 IP (13 games/7 starts) for Helena last year. The Brewers are developing him as a starter, though some believe he will be better suited as a reliever in the long run. Diaz posted a 2.21 ERA with 23 strikeouts and five walks in 20 IP (7 games/5 starts) for Milwaukee’s Arizona League team last year. His 2015 season didn’t start until late July after undergoing surgery in March, so it will be interesting to see what he does over the course of a full season.

RHP David Lucroy, younger brother of Brewers catcher Jonathan Lucroy, will make his full-season debut with the Timber Rattlers.
