Kevin Whelan opened this season as a rather forgettable part of a potentially memorable Triple-A pitching staff. Legitimate prospects filled the rotation, and the bullpen was dotted with returned Rule 5 picks and veterans with big league experience.
Then there was Whelan, the last remaining piece of the 2006 Gary Sheffield trade. He was a fallen prospect, a guy who always walked too many batters and finally reached a new low with a 6.02 ERA between Double-A and Triple-A last season.
Whelan’s been a completely different pitcher this year. As Scranton/Wilkes-Barre’s closer, he’s cut down on the walks significantly. He has a 1.73 ERA, 17 saves, and he’s allowed just 17 hits and six walks through 26 innings. He’s struck out 28, and his 0.88 WHIP is the lowest on the team.
“It is the command, which translates to confidence,” pitching coordinator Nardi Contreras said in an email.
Contraras was the second person I talked to who mentioned confidence when explaining Whelan’s sudden improvement. He’s always had a good fastball and a big splitfinger — and he’s had some real success from time to time — but it seems that things are just now coming together. If the Yankees find an opening for a one-inning guy, Whelan would surely be the front-runner for the job. It’s worth noting that he’s been especially good against left-handers, holding them to a .178 batting average with 19 strikeouts and only two walks.
It’s also worth noting that Whelan’s not on the 40-man, and the Yankees have found more openings for multi-inning relievers than short relievers this season. Jonathan Albaladejo had even better numbers as Scranton/Wilkes-Barre’s closer last season — and he actually was on the 40-man — but Albaladejo barely got a look at the Major League level. So Whelan might not be looking for apartments in the city, but he’s surely put himself on the map. It’s impossible to ignore a guy who’s always had the potential and is just now finding the consistent results.
 • Gary Sanchez is back on the Charleston active roster. He returned Saturday after being sent to extended spring training for what appears to be some combination of a bad back and a bad attitude,  probably more of one than the other. He had a hit and drew a walk in his first game back.
• Greg Golson has been activated from the Triple-A disabled list, a move came one day after Scranton/Wilkes-Barre’s most productive outfielder, Justin Maxwell, went on the disabled list with a jammed shoulder. Maxwell actually has a higher slugging percentage than Jorge Vazquez and homered in three games in a row just before the injury. For the season he’s hitting .260/.358/.588 and might have hit his way into a big league role had Andruw Jones not started hitting lately.
• Speaking of banged-up Triple-A players who might or might not be playing their way into a call-up: Carlos Silva was scratched from a start on Sunday  because of tightness in his shoulder. Doesn’t seem too serious. Manager Dave Miley told Donnie Collins, “We’re just pushing him back.”
• If there’s no spot for Whelan as a short reliever in New York, the Yankees certainly have options for long relief out of Triple-A. George Kontos and Buddy Carlyle are still pitching well in long relief for Scranton/Wilkes-Barre. Kontos is holding right-handers to a .143 average with 24 strikeouts and four walks. Out of the rotation, tonight’s starter D.J. Mitchell has a 2.78 ERA and pitched seven scoreless in his most recent outing.
• After hitting .218/.292/.287 in April, Kevin Russo hit .316/.384/.408 in May. Brandon Laird made a similar turnaround, from .184/.213/.289 in April to .307/.343/.406 in May. Jesus Montero went the other way, from .365/.360/.473 to .269/.333/.413.
• Strange stuff in Double-A Trenton  where hitting coach Julius Matos was ejected last week, then got into some sort of argument with manager Tony Franklin and has since been removed from his role. Popular roving hitting instructor James Rowson has taken over the job for now. It’s unclear whether Matos will return in any capacity.
 • Austin Romine is the only Trenton regular hitting better than .277, and he’s missed a few games with a stiff neck and back after a home plate collision.  Romine has certainly been the high point of the Double-A lineup. Melky Mesa is back to being an all-or-nothing hitter, Bradley Suttle is hitting for good power but a .233 average and Corban Joseph has been good but not great.
• I talked about him a little bit in today’s chat: Trenton reliever Tim Norton is starting to get some attention. Injuries have always been the biggest knock on the guy. This year he’s healthy and putting up incredible numbers (44 strikeouts in 29 innings, for example). One scout told Bill Madden that Norton is, “better than (Joba) Chamberlain right now.” 
• Manny Banuelos has a 2.12 ERA and Dellin Betances has a 1.99, so those two are doing just fine despite higher-than-you’d-like walk totals. Craig Heyer, a guy the Yankees sent to the Fall League this offseason, has been awfully good since stepping into the rotation to fill in for some injuries.
• Tampa third baseman Rob Lyerly made the Florida State League all-star team, but as expected, the High-A roster is lowest of the four affiliates in terms of prospect buzz. Starters Brett Marshall and Jairo Heredia, though, are starting to do some things. In Heredia’s past three starts he’s allowed one earned run through 21 innings. He’s walked two and struck out 22. He’s another of those “if-things-go-right” prospects.
• J.R. Murphy remains the best all-around hitter in Low-A Charleston, but first baseman Kyle Roller leads the team with a .563 slugging percentage and corner outfielder Ramon Flores leads with a .407 on-base percentage.
• Slade Heathcott in April: .370/.453/.630. — Slade Heathcott in May: .216/.283/.289.
• The amateur draft begins tonight. The Yankees don’t have a pick until the supplemental first round — No. 51 overall — but they’ll almost certainly be part of the story with pick No. 1. The Pirates are reportedly planning to take Gerrit Cole,  the former Yankees first-round pick who ultimately signed with UCLA rather than join the Yankees minor league system.
