Trey Gregory-Alford’s triple-digits fastball has him in rarified air inside the history of Colorado’s preps baseball, and his Cougars in position to reach the regional tournament for the first time in seven years.

The senior has been clocked at 101.4 mph on the mound this spring for Coronado, which is currently Class 4A’s “last team in” according to the CHSAA Selection and Seeding Index.

He’s 2-0 with a 2.22 ERA and a class-most 79 strikeouts in 34 2/3 innings.

And while batters try to find a way to catch up to him — as he’s tossed double-digit Ks in each of his last four appearances — he’s sizzling from the plate as well, batting .520 with 31 RBIs and six home runs on the year.

With 11 days left in the regular season, the questions are — Can he sustain his astronomical performance from the mound and plate? And will it be enough to extend Coronado’s season? And for how long?

In this week’s look-in on 5A and 4A baseball, let’s look at the teams currently flirting with the postseason bubble.

Class 5A

Last four in: No. 29 Pueblo West (10-9), No. 30 Centaurus (10-8), No. 31 Loveland (8-10), No. 32 Fairview (9-9).

First four out: No. 33 Air Academy (8-11), No. 34 Dakota Ridge (8-11), No. 35 Eaglecrest (9-9), No. 36 Monarch (7-11).

A baseball season is known for its ebbs and flows, and No. 30 Centaurus (10-8) has been a shiny example of it up to this point.

The Warriors are back inside the playoff picture after they won three straight following a five-game losing streak.

Zak White has been key for them all season, and especially this past week, where he continued to dominate with a 0.27 ERA over 25 2/3 frames.

Last week, with the losses starting to close the door on Centaurus’ postseason hopes, he threw four no-hit innings and drove in three runs in a 10-3 win over No. 16 Silver Creek.

White’s hitting .453 with 24 RBIs on the year.

Meanwhile, No. 29 Pueblo West is one spot ahead thanks to its strong 5-2 start inside the 5A/4A South Central League. Freshman Cameron Mares — who is 4-1 with a 1.77 ERA in 27 2/3 innings this season — threw six innings of one-earned run ball in a 6-2 win over 4A No. 21 Pueblo Central on Tuesday, the Cyclones’ third win in four games.

Back of both of them, and currently on the wrong side of the bubble, No. 36 Monarch (8-11) has won two of three following a four-game slide.

The Coyotes beat No. 51 Boulder 9-1 behind Clay Hafner’s three RBIs on Thursday. Monarch is at No. 32 Fairview (9-9) on Saturday.

Class 4A

Last four in: No. 29 Evergreen (11-8), No. 30 D’Evelyn (11-9), No. 31 Mesa Ridge (11-9), No. 32 Coronado (12-9).

First four out: No. 33 Standley Lake (10-8), No. 34 Longmont (9-10), No. 35 Niwot (8-10), No. 36 Conifer (7-11).

No. 32 Coronado (12-9) and No. 27 Canon City (11-8) head into their two-game season series next week tied atop the 4A Colorado Springs Metro League.

If either of them can win twice, no tiebreakers will come into play and the winner will earn an automatic bid into the regional field.

Elsewhere on the bubble is offensive-juggernaut Mesa Ridge (11-9) at No. 31. The Grizzlies are averaging almost 10 runs per game and are 7-0 when they score at least 13.

They split with the Cougars this past week, winning the first game Tuesday, 14-8, behind Mykah Clark’s home run and five RBIs.

No. 29 Evergreen (11-8), meanwhile, has been streaking at the right time with six wins over its last seven games.

Tied with No. 2 Golden atop the 4A Jefferson County standings, the Cougars host No. 59 Alameda on Saturday. The last time out against the Pirates — on April 2 — freshman James Mauro had a home run and seven RBIs in a 22-0, three-inning win.
