Prospect numbers of note: May edition

The second month of the Minor League season brought the continuation of some interesting story lines from April -- like Alex Bregman's power surge -- as well as some new narratives, such as Padres No. 22 prospect Alex Dickerson emerging as perhaps the hottest hitter in the Minor Leagues. Here's a look at some of the most interesting statistics from the month of May in the Minors. (Note: all stats are through Monday's games, unless otherwise noted.)

0.00: Julio Urias, Triple-A Oklahoma City (LAD), ERA: This is why there was so much hype around Urias' Major League debut last Friday. The 19-year-old southpaw is the only qualified Minor League pitcher (i.e., hurlers with 0.8 innings pitched per team game played) to not give up an earned run in May. He last gave up a run for Oklahoma City on April 22 and has followed that up with 27 straight scoreless innings at the Triple-A level. Obviously, that didn't hold up when he made the jump to the Majors as he gave up three earned runs in 2 2/3 innings against the Mets, but he'll get another chance to start a Major League scoreless streak after being recalled again with the news that Alex Wood is on the disabled list with elbow soreness.

0.75: Jameson Taillon/Chad Kuhl, Triple-A Indianapolis (PIT), WHIP: As if the Indianapolis staff couldn't look any better, both Taillon and Kuhl posted the best WHIPs in the International League from May 1-30. (Note: Kuhl was slated to pitch for the Indians Tuesday.) What's more, this is an exact tie as each has allowed 24 combined walks and hits over 32 innings. Most have pegged Taillon and Glasnow as the two Pirates pitching prospects most likely to help the big club before the All-Star break, but the groundball-dependent Kuhl, who had the best May ERA at 0.84 entering Tuesday, has worked his way into the conversation as well.

.329: Alex Bregman, Double-A Corpus Christi (HOU), ISO: If you thought Bregman's impressive introduction to Double-A in April was going to be a mirage, it wasn't. The Astros' top prospect showed perhaps even more power in May as 16 of his 29 hits went for extra bases (seven homers, nine doubles). His .648 slugging percentage in the month was fourth-best among all Double-A batters, while his .326 isolated slugging percentage (ISO) on the season is tops among the same group. Bregman has hit three times the homers (12 vs. four) in 131 fewer at-bats this season as compared to last. He discussed what's gone into the power surge in last week's MiLB.com podcast.

.467, Alex Dickerson, Triple-A El Paso, average: If May belonged to any one player, it might be Dickerson. The Padres' No. 22 prospect was 28-for-60 (.467) on the month with five homers, five doubles and 21 RBIs in 16 games for El Paso, entering Tuesday's play. His 28-game hitting streak is the longest in the Pacific Coast League this season by 11 contests. The 26-year-old has been particularly effective at home with an even .500 average (25-for-50) in 15 games. Dickerson spent May 3-12 with the Padres but only received one start there. As arguably the Minors' hottest hitter, he's earned the right to a longer look as the summer progresses.

11: Jarrett Parker, Triple-A Sacramento (SF), home runs: The Giants' No. 18 prospect was tied for the Minor League lead in May homers with 11, entering Tuesday's play. But here's the thing: Parker needed only 72 plate appearances to do it, 43 fewer than Memphis' David Washington with whom he shared the MiLB lead. The 27-year-old outfielder was called up to the Majors twice in May -- from May 9-12 and again on May 24 to present when Angel Pagan was put on the disabled list. Parker has gotten more regular playing time with the Giants this second time around, and having a .281/.366/.615 line with 13 homers in 36 games with the River Cats on the resume has forced the issue there.

12.2: Blake Snell, Triple-A Durham (TB), K/9: The Rays' top prospect hasn't performed entirely up to standard in May as he's posted a 4.05 ERA and 1.28 WHIP in five starts for Durham, all while pitching at least six frames only once in that span. But he has continued to miss plenty of bats. Snell has struck out 36 batters in 26 2/3 innings in May -- not counting his start Tuesday night -- and now leads all Triple-A hurlers with a 12.2 K/9 on the season. (Yes, his K/9 for both April and May in the Minors was 12.2) That's higher than Glasnow (11.1), Archie Bradley (10.4) and Urias (9.7). The Rays will want MLB.com's No. 12 overall prospect to become a little more efficient so that he can make it deeper into outings before they give him his second Major League start, but it's pretty clear his stuff can be untouchable at times against Triple-A bats.

26: Bobby Bradley, Class A Advanced Lynchburg (CLE), walks: The Indians' No. 3 prospect is known for his power, but his patience at the plate was also on display in May. Bradley led the Minors with his 26 free passes for the month, meaning he walked in 22.2 percent of his plate appearances. This doesn't mean the 20-year-old first baseman had a great nose for the strike zone, however, as he struck out in 23.9 percent of his plate appearances and hit just .180 for the month. All the walks allowed him to post a .376 OBP for May. Still, his 11 homers (five of which came in May) on the season are tops in the Carolina League, while his 63 strikeouts and 35 walks both rank second. If you're looking for a Class A Advanced version of a three-true-outcomes player, look no further.
