This week’s episode of “Who really is 5A’s best team?” didn’t provide much clarity.

Under the lights in a showdown between the top two teams in Colorado’s Class 5A last Friday in Parker, Regis Jesuit blasted Legacy, ending what had been a short stay at No. 1 for the Lightning.

The Raiders (10-3) went on to beat No. 27 Mountain Vista and No. 23 Legend but remain at No. 2 in CHSAA’s latest rankings.

Arvada West (11-3) is currently on top after winning nine straight. Over the past week, the Wildcats swept both No. 13 Ralston Valley and No. 34 Bear Creek in two-game sets.

Rounding out 5A’s top five, Erie (14-2) is third after it spent time at No. 1 following an 11-game winning streak to open the season.

Broomfield (11-3) beat Erie last week and has won seven straight, moving into fourth.

Legacy (10-2) rebounded from its 16-6 loss to Regis with comfortable wins over No. 37 Monarch and 4A No. 35 Centaurus, sitting fifth.

Let’s take a deeper look into the top of the 5A and 4A rankings.

Class 5A

Top 10: Arvada West, Regis Jesuit, Erie, Broomfield, Legacy, Cherry Creek, Pine Creek, Rocky Mountain, Chaparral and Northfield.

Games of the week

No. 1 Arvada West at No. 10 Northfield, Thursday at 4 p.m.

Arvada West (11-3) opened the season with a win over defending champ Cherry Creek and hasn’t lost in-state this season.

Next Thursday, the Wildcats and junior ace Cooper Vais (5-0, 0.28 ERA) will travel to Northfield. The Nighthawks (10-4) had a tough week, losing to 5A No. 11 Fairview and 4A No. 11 Lutheran before beating 5A No. 12 Vista PEAK Prep on Tuesday.

In the two teams’ last three meetings, Arvada West is 3-0 with a scoring margin of 36-1.

No. 5 Legacy at No. 3 Erie, Thursday at 4 p.m.

Legacy (10-2) will have its hands full for the next couple of weeks, with games against 5A No. 8 Rocky Mountain, No. 11 Fairview, No. 3 Erie and No. 4 Broomfield.

And for the time being, it’ll be without star shortstop Chase Hoelting. The senior was hitting .632 before going out injured earlier in the month.

Erie (14-2) lost two of three before bouncing back with wins over 4A No. 13 Holy Family and No. 48 Frederick this week.

Against Holy Family, Dayton commit Boston Coslett hit his sixth homer of the season to break up a scoreless game in the ninth inning of Erie’s 4-3 win. Maddox Burnett, committed to BYU, tossed a one-hitter over eight innings, fanning 15.

Class 4A

Top 10: Roosevelt, Falcon, Golden, Palisade, Canon City, Grand Junction, Durango, Windsor, Ponderosa and Fort Morgan.

Games of the week

No. 2 Falcon at No. 5 Canon City, Saturday at 10 a.m.

The Falcons (13-1) followed their first loss of the season — against No. 9 Ponderosa on April 4 — with a two-game sweep of 3A No. 11 Elizabeth and a 23-4 pounding of No. 35 Manitou Springs.

Leading the way, Aaron Jaquez is third in the state with 29 RBIs and third in classification with a .630 batting average.

Canon City (12-2), meanwhile, got another deep ball from senior Trey Schumacher this past week. He’s tied for Colorado’s home run lead after belting his sixth of the season in Canon City’s win over No. 54 Mesa Ridge on Tuesday.

5A No. 9 Chaparral at 4A No. 9 Ponderosa, Monday at 4:15 p.m.

Ponderosa (11-4) started the season 0-4, which included losses to No. 4 Palisade and No. 6 Grand Junction. But the Mustangs haven’t lost since the middle of March.

Leading the way, Jackson Phillips leads 4A with a .652 batting average. He went 9 for 12 at the plate in three games this past week and drove in nine runs.

Chaparral (10-5) suffered its worst loss of the season on Wednesday, falling 18-3 at No. 18 Heritage, then bounced back with an 11-5 win over Rock Canyon on Thursday. In the win, Colton Pamenter finished with a career-best three RBIs.

5A No. 8 Rocky Mountain at 4A No. 8 Windsor, Tuesday at 4 p.m.

Nobody of late has been able to hit senior pitcher Bradley Mallette, who hasn’t allowed a run in his past two outings for Rocky Mountain (10-4). In a 2-0 win over No. 25 Fossil Ridge on Thursday, he threw a four-hitter, striking out eight.

Windsor (11-3) won three in a row after splitting with 5A No. 46 Loveland last week. Easton Gattis has the second-best on-base percentage (.724) among freshmen in the state and the third-highest batting average (.579).
