It seemed like only a matter of time.

Seneca Valley’s baseball program has been so good for so long — producing numerous prospects over a number of years — that a few of these guys might reach the big leagues.

A couple of them already have, of course.

Outfielder Jason Conti spent parts of five seasons in the majors, primarily with the Arizona Diamondbacks.

Left-hander Zach Jackson pitched for a few teams — mainly Cleveland and Milwaukee — as a starter and reliever.

Now two other Seneca Valley graduates are knocking on the door.

Kevan Smith, 26, a catcher in the Chicago White Sox system, is hitting .300 in 30 at bats for Class AAA Charlotte. He stands 6-foot-4, 230 pounds, and may be an injury away from a call-up to the big club.

Right-handed pitcher Cory Mazzoni, 25, a second-round draft choice by the New York Mets in 2011, was traded to the San Diego Padres before this season began. Previously a starting pitcher, Mazzoni has been working as a reliver and shining for Class AAA El Paso early this spring.

In 8.1 innings with the Chihuahuas, Mazzoni has allowed only one run while striking out 13 and walking just one.

Both Smith and Mazzoni have been sidetracked in their bids to become major leaguers.

Considered a prospect as a catcher as a high school senior, Smith opted to go to the University of Pittsburgh as a quarterback. He started a handful of games as a freshman for the Panthers, but his football career faded.

He played for the Pitt baseball team, put together a couple of stellar seasons and was drafted by the White Sox in the seventh round of 2011. He also hit .347 with 30 RBI for the Butler BlueSox in the second summer of that franchise’s existence.

Mazzoni was picked by the Washington Nationals in the 26th round as a senior with the Raiders in 2008. He opted to pitch at North Carolina State and was selected by the Mets three years later.

While getting a spring training look with the Mets last spring, Mazzoni suffered a triceps injury that affected much of his 2014 season and his stature as a prospect.

Now both of these guys seem back on track in pursuit of an appearance in what professional baseball players affectionately call “The Show.”

A third SV graduate, pitcher Kyle Helisek, signed with the Frontier League’s Washington Wild Things last week. He spent three years in the St. Louis Cardinals’ farm system and earned a spot in the Florida State League All-Star Game only last year.

Now he’s trying to re-establish himself as a prospect through the Wild Things.

No wonder every player in baseball recalls with pride and excitement his respective major league debut.

It takes so much to get there. Most guys never do.

Here’s hoping Smith and Mazzoni realize that moment soon.
