VerHagen allowed three hits over six innings, Wade Gaynor homered early and Tyler Collins went deep for the second straight game as Lakeland blanked Dunedin, 3-0, to sweep its best-of-3 Florida State League semifinal series.
Selected in the fourth round of this year's Draft, VerHagen (1-0) struck out two and walked a pair in the Flying Tigers' second straight shutout. They will play Jupiter or St. Lucie in the best-of-5 Championship Series.
"I was just trying to keep my two-seamer down in the zone and get those ground-ball outs," VerHagen told The (Lakeland) Ledger. "I let my defense do the work and they were great all night."
Gaynor homered leading off the second inning against Dunedin starter Sean Nolin and Collins greeted reliever Frank Gailey with his second homer in as many days to start the ninth for a 3-0 edge.
"It was nice to get an early lead," Gaynor told the newspaper. "Our staff the past few games has been the reason we've won. Back-to-back shutouts in the playoffs is almost unheard of. They've been lights out. If we can score one or three runs with them pitching like that, we have a great chance to win."
James Robbins drove in Lakeland's other run with a single in the seventh.
Dan Bennett struck out five and yielded one hit over two dominant innings before Melvin Mercedes fanned two in the ninth for his first postseason save. The bullpen effort came a night after Matt Crouse recorded the final six outs in the series opener.
VerHagen isn't new to postseason situations. Before transferring to Oklahoma and, eventually, Vanderbilt, the 21-year-old right-hander won the 2011 Junior College World Series with Navarro (Texas) College.
The Flying Tigers' trio did well in shutting down a pair of rehabbing Major Leaguers in J.P. Arencibia and Brett Lawrie, who combined to go 1-for-7 with a walk.
Arencibia, sidelined with a fractured right hand, is due to return to Toronto by the end of the week, while there is no timetable on Lawrie, out since Aug. 3 with an oblique injury.
