CHICAGO -- Zack Collins had himself quite the month of May.
The White Sox No. 9 prospect, as ranked by MLBPipeline, erased all memory of his slow April start by hitting .322/.508/.540 last month. Collins continues to show an impressive knack for getting on base, drawing 33 walks while striking out 29 times. For the season, Collins has 52 walks and 54 strikeouts in 206 plate appearances.
Collins also demonstrated his power during May, clubbing five of his seven home runs and slugging four of his six doubles. He improved his season-long OPS to .926, trailing only top prospect Eloy Jimenez at Double-A Birmingham. Collins' .461 on-base percentage leads the Southern League.
Here is a rundown of other White Sox top prospects:
Michael Kopech, RHP, Triple-A Charlotte
Kopech hit a speed bump on May 11, allowing eight runs -- all earned -- in 3 1/3 innings. Since that outing, however, he has returned to form. In his three starts since, the White Sox No. 2 prospect has a 2.00 ERA in 18 innings, walking eight and striking out 24. Opposing hitters hit .148/.239/.230 during that time.
In Kopech's most recent start, on May 28, the 22-year-old went six innings, giving up two runs on three hits against Pirates-affiliated Indianapolis. He struck out seven hitters and walked two.
Kopech's season-long ERA sits at 3.86 in 10 starts, and his 68 strikeouts are good for second in the International League.
Eloy Jimenez, OF, Double-A Birmingham
After seeing his 15-game hitting streak snapped earlier this season, Eloy Jimenez has simply started a new one.
Jimenez entered Friday night with a 10-game hit streak, his second such streak of at least double-digit games. The No. 3 overall prospect in baseball collected multiple hits in five of those 10 games, including a 4-for-4 performance on May 19 to start the new streak.
Over the course of those 10 games, Jimenez hit .425/.489/.800 with three home runs, 11 RBIs, four doubles and five walks. Jimenez's 10 home runs this season are tied for first in the Southern League with three others, including fellow White Sox prospect Seby Zavala. Jimenez's season-long .996 OPS also leads the league.
Dylan Cease, RHP, Class A Advanced Winston-Salem
The other prime prospect acquired in last season's Jose Quintana trade, Cease, much like Jimenez, continues to find success early this season.
Chicago's No. 5 prospect owns a 2.96 ERA through 10 starts, striking out 64 batters and walking 24 in 51 2/3 innings. He made his most impressive start of the season last week, giving up one run on four hits in 7 1/3 frames. He walked two and fanned nine in that May 24 outing vs. Astros-affiliated Buies Creek.
Cease has completed six innings in five of his 10 starts this year and is on pace to surpass the 93 1/3 innings he threw last season, his previous professional high.
