Two weeks' worth of results aren't likely to move the needle much on a pitcher's prospect stock. Plus, one needs a little more information than strikeouts and earned run average to determine that a pitcher has legitimately lifted either his floor or his ceiling.

Which brings us to Alex Reyes: The Cardinals' prospect is ranked third in St. Louis' system according to MLB.com and checks in at No. 100 on the site's Top 100 prospects list. Those rankings are from before the season. Since Opening Day, Reyes has already done enough to likely warrant a spike up both lists, mostly on the strength of a fastball that now touches triple digits.

Reyes has hit 100-plus mph at least a half-dozen times this year through two starts. He's in the upper 90s consistently, too, averaging 98 mph on his heater on Opening Day, according to Palm Beach pitching coach Randy Niemann.

That's a notable jump for Reyes, who has flashed triple digits before but mostly sat 93-to-95 mph in 2014. He's stretched that band to where almost all of his fastballs are coming in at 95-plus mph. That makes him one of the hardest-throwing starting pitchers in the world right now -- Yordano Ventura's 96.2 mph average velocity is the highest among qualified starters in the Majors right now.

Unlike last week's Stock Watch focus, the Orioles' Branden Kline, Reyes' velocity jump is merely a matter of a 20-year-old adding strength. In fact, many observers expected Reyes to add heat with age, although one can't predict that anybody will sit in the upper 90s.

Reyes is more than a live arm at this point, though. While with Class A Peoria in 2014, he and pitching coach Jason Simontacchi targeted two specific areas for Reyes to improve: The first was that Reyes lacked a veteran's routine; then there was his lackluster changeup, which needed dramatic sharpening.

The routine was an easy enough fix, and the 20-year-old now has the habits needed to maintain and improve his repertoire and command throughout a season.

His improved changeup demonstrates Reyes' ability to adapt to coaching and apply lessons. Prior to 2014, the change was clearly Reyes' worst pitch and showed less potential than his blazing fastball or rotation-heavy curve.

With Simontacchi's help, the offspeed offering came a long way last season. In just a few months, it went from a below-average pitch to a consistently average one that sometimes comes in above average.

Niemann, who is coaching Reyes at Class A Advanced Palm Beach this year, didn't see much of Reyes before this spring but had heard within the organization about Reyes' work with Simontacchi. Before he even saw Reyes throw the pitch, he had faith that the changeup could be a weapon for the New Jersey native.

"One question I asked him in Spring Training, because I knew he'd been working on it, was 'Do you throw your changeup to right-handed hitters?'" Niemann said. "His response was exactly what you want to hear from any pitcher, let alone from a young 20-year-old. 'I love throwing it to right-handed hitters.'

"That tells me right there that the maturity and the confidence he has in that pitch is going to make it, to me, not just an average pitch but an above-average changeup. He has an above-average change."

So, we're looking at a triple-digit fastball and an above-average changeup. How about the breaking ball?

Reyes' changeup is more consistent than the curve right now, but his curveball probably has greater potential. He gets plenty of spin on the offering -- what's lacking is consistent location.

This year, learning to command the breaking ball is Reyes' chief goal, and he and Niemann are already hard at work to make it a consistently above-average pitch. Palm Beach manager Oliver Marmol said after Reyes' second start that the curve has improved notably just since Opening Day.

"We talk all the time about how Major League hitters -- they see 95 and above on a nightly basis," Niemann said. "That's not going to bother them a whole lot. What will bother them is if you can change speeds and locate the fastball and throw secondary pitches for strikes behind in the count. Those are the things he's striding toward.

"If we can talk about somebody who has three above-average pitches, you're talking about a wonderful prospect. At 20 years old, to make that statement is fantastic."

Just for reference, MLB.com only had five right-handed pitchers who graded out with plus fastballs and two above-average secondary pitches heading into 2015 -- Lucas Giolito, Noah Syndergaard, Jon Gray, Mark Appel and Eddie Butler, all of whom rate among the game's top 35 prospects. If Reyes' maintains his early improvements, that's the range where fans might expect to find him on prospect lists by year's end.

Two hot…

Mets OF Michael Conforto, Class A Advanced St. Lucie: The Florida State League is supposed to be a tough place to hit, but Conforto is chewing FSL pitching up and spitting it back out -- often over the fence. The Oregon State product hit .435 with a 1.430 OPS from April 14-21. He's hitting .366 with four homers, which is tied for second in the Minors and tops in the FSL this year. The 22-year-old is an advanced hitter, collecting more walks than strikeouts through 11 games. MLB.com puts a 55 on his hit tool and a 60 on his power, though his .338 Minor League average may bump that hit grade up if it continues through 2015.

Brewers LHP Kodi Medeiros, Class A Wisconsin: The southpaw is capable of bringing mid-90s heat with a ton of sink from a low 3/4s delivery. All that movement has given Midwest League hitters fits through two starts. He's recorded 12 strikeouts over 10 1/3 innings, and of the 23 times opponents have put a ball in play against him, 22 went for ground balls. Overall, the Hawaiian has a 0.87 ERA through two outings.

…And one not

Brewers OF Monte Harrison, Class A Wisconsin: Milwaukee's second-round pick from the 2014 Draft is your typical five-tool talent. A two-sport athlete in high school -- he was going to play wide receiver and outfield at Nebraska if he didn't sign -- Harrison has sky-high upside and a sub-basement floor because of his loud-but-raw tools. There's still a lot of time for the 19-year-old to develop, but it's been a slow crawl out of the gate. Through 10 games, the Missouri native has a .118 average with 19 strikeouts in 34 at-bats. His 46.3 strikeout percentage is the sixth highest in all of Minor League Baseball through Monday, and he entered Tuesday mired in a 1-for-16 slump.
