Top hitter: Oregon State won't rely on the long ball to outpower opponents. Instead, it looks toward Steven Kwan and Nick Madrigal to get on the basepaths at the top of the order. Madrigal leads the Beavers with a .383 average, 85 hits and 52 runs scored. The Dustin Pedroia comparison is suitable for more than just the second baseman's 5-8 frame — he also shares the same hard-nosed approach to the game, all-conference defense and sneaky power (19 doubles this year). Madrigal's recorded at least one hit in five of Oregon State's six games this tournament.

Top starter: Righty Jake Thompson is one big piece in the nation's only pitching staff with a sub-2.00 ERA for the year. The 2017 Dick Howser Award finalist leads the country in victories (14-0) to go along with a 1.52 ERA (fifth) and 113 strikeouts. Thompson is 2-0 this postseason with five runs allowed in 15.1 innings. Vanderbilt touched him up for four of those runs in his Super Regionals appearance.

Top reliever: The Beavers have used freshman Jake Mulholland more than anyone else in their bullpen, and the southpaw has delivered in his first year. Mulholland has pitched 2.2 innings this tournament without an earned run, adding to a season where he's led Oregon State with six saves — to go along with six wins and a 1.31 ERA. Mulholland is comfortable eating up multiple innings, setting up or closing, which makes him a valuable asset out of the bullpen.
