Jack Flaherty, 19-0 on the mound for Harvard-Westlake the last two seasons, faces another strong challenge on Tuesday from Mission Hills Alemany in a game for first place in the Mission League.
Flaherty is 6-0 with an 0.70 ERA this season and has 85 strikeouts in 50 innings while surrendering just 24 hits.
Alemany Coach Randy Thompson isn't backing down one bit. He's going to send out his junior ace, Brandon Ponticelli, who's 7-0 with an 0.63 ERA.
Alemany has a history of not being intimidated by the Wolverines and their standout pitchers. In 2012, Cody Thompson and Alemany knocked off the Wolverines and Lucas Giolito, 2-1.
Alemany (16-4-2, 5-1), Harvard-Westlake (16-4-1, 4-1-1) and Loyola (16-4-1, 6-1-1) are battling for the league title. Loyola still has to face Alemany in a two-game series next month.
Another big series this week involves Kennedy and Sylmar in the Valley Mission League. They play Tuesday at Sylmar and Thursday at Kennedy. If either team sweeps, then the league race is pretty much over.
In the Western League, first-place Hamilton (6-0) plays at Palisades on Tuesday and at home on Thursday.
In the Trinity League, first-place JSerra (15-5, 7-2) has a two-game series with Servite (13-8, 5-3), which has been getting terrific pitching of late.
