The last time the Musgrave and Shively brothers all pitched together was when they won the Flint Hills League championship.

But that was a decade ago when two of the four boys were 8-year-old pitchers, and their two younger brothers were heaving baseballs beside them at the age of 6 for Carbondale’s Little League team.

This season, the brothers are back together, and once again a baseball team’s success stemmed from the two sets of siblings on the mound.

“They’re pretty much our whole staff,” said Santa Fe Trail coach Brent Mumford, whose 20-3 team has ridden the foursome — Rob and Curtis Musgrave, and Brian and Jay Shively — into this weekend’s Class 4A state tournament in Salina.

“It’s a pretty unique situation to have four with this much talent,” added Mumford, who actually has six sets of brothers playing at SFT.

The second-seeded Chargers will take on seventh-seeded Larned (17-6) today at 11 a.m. at Dean Evans Stadium. Wamego is the top seed at 18-1, but SFT has the most victories in the eight-team field.

While the four brothers have earned all but one win and one loss for SFT’s pitching staff this season, the Musgrave and Shively brothers need only three more wins to recapture the title form from their youth.

“That would be awesome to do it all again,” SFT ace Rob Musgrave said.

The senior left-hander — who holds Kansas’ all-time strikeout record and has signed to pitch for Wichita State next year — leads the team with an 8-1 mark and 0.25 earned-run average with 112 strikeouts in 55 innings.

“Rob is a real special athlete,” Mumford said. “I don’t think too many coaches have many like him come through their programs.”

But SFT’s success isn’t solely based on Rob.

Curtis, Rob’s younger brother, has been equally effective, entering this weekend with a 5-0 record, 1.63 ERA and 63 strikeouts in 382/3 innings.

Then there are the Shivelys.

Mumford said Brian, a sophomore, was the team’s “toss-up No. 2-3 starter alongside Curtis.” His stats seem to prove that. Brian is 6-1 with a 1.75 ERA and has 55 strikeouts in 40 innings.

Jay, a senior who played a big role in SFT’s third-place finish at the state tournament two years ago, hasn’t factored in as much the last two seasons.

He won only four games in two years, but has been solid in relief roles, Mumford said.

A big part of the Chargers’ chemistry has been the brother’s competitiveness, according to Brian Shively.

“We’re real close, but real competitive,” he said. “I think that has helped us challenge not only ourselves but each other.”

SFT’s slingers also can slug. Curtis, Jay and Rob are batting over .400 — Rob leads the team with a .506 average — and have at least 24 RBIs.

But that kind of productivity at the plate or on the mound isn’t surprising to the players’ pops, Bill Musgrave and Jim Shively, who first got the foursome together on the same field in the Shively’s backyard.

“Even when they were 6-year-olds, I had a feeling that all of them would make excellent pitchers,” Jim Shively said. “I can’t really explain how it’s worked out, but it’s been pretty special.

“Around here, people say you better watch out for the Musgrave and Shively brothers.”
